Interesting idea.  Worthwhile if you need to access either Boot Camp or Mac.  Click here to learn.

Eu acreditava que poderia rodar tudo no Ubuntu usando o VirtualBox, ledo engado. Bom, o VirtualBox é um aplicativo fantástico que permite que você instale um novo Sistema Operacional dentro do seu próprio sistema. A ideia de maquinas virtuais não é nova e não necessariamente é inútil, só que não serve para tudo. Breve vamos aprender aqui a usar o VirtualBox e todas as suas configurações e funções.

Vamos ao que interessa, formatando a maquina e instalando os dois sistemas operacionais.

Fiz todo este processo em um Itautec W7645, Celeron 2gb, com 160 HDD e placa de vídeo integrada da Intel. Atualmente é minha maquina para tudo, o PC de casa morreu e também passo muito tempo na rua, trabalho, faculdade, casa de minha noiva. E acabo sempre com meu note no colo mesmo. Lembre-se que para este processo é aconselhável fazer um backup completo de seu computador, para o processo iremos re-fatiar todo o HD e para não correr o risco de perder alguma coisa, ou você grava tudo em dvd ou então passa para um pendrive ou HD Externo que foi a minha opção.

Os sistemas operacionais escolhidos foram o Windows 7 Home Premium e o Ubuntu Netbook Remix. O Win7 acho que se você está lendo este blog, você deve conhecer, se não conhece, vou  a uma rápida explicação sobre a escolha. Durante anos o Windows XP vem sendo o SO mais usado no Brasil e no mundo a fora, a grande maioria dos usuários se recusa a sair do XP simplesmente porque ele funciona, ele supre todas as necessidades de um usuário médio ou para os usuários de internet. Ele ainda recebe todos os programas atualizados, possui uma gama enorme de desenvolvedores, seja de programas ou até mesmo de temas para deixa-lo mais bonito, então para que sair? Ele é inseguro, instável, passivo de muitos erros e falhas de segurança.

O Windows 7 veio para abocanhar a fatia do mercado que o WinVista não conseguiu, o novo sistema da Microsoft além de bonito é mais seguro, possui diversas ferramentas de acessibilidade que ajudam no dia a dia, e é tão leve quanto o Windows XP. Diferente do Vista que transformava qualquer 2gb de RAM em uma verdadeira carroça. Eu gosto do Windows 7, eu o acho fantástico. Mas ele ainda é Windows e isso o remonta a famosa Tela Azul, Erros de Partição (que foi o que me aconteceu) e uma dezena de outros problemas que só um sistema operacional de retalhos poderia ter. Mas mesmo assim eu gosto dele. Bom, a decisão de usa-lo tem em vista a função que ele terá no meu notebook. Ele será um verdadeiro console de jogos para mim. Infelizmente a Industria possui diversos acordos com Microsoft e Apple de reserva de mercado, assim os jogos que poderiam perfeitamente serem desenvolvidos para Linux, ficam restritos ao Windows e ao OS X.

O Ubuntu Netbook Remix foi uma opção um tanto quanto pessoal. Eu acho ele muito bonito e vem com bem menos coisas instaladas nativamente, é um prato cheio para mim que gosto de sair procurando meus programas e de instalar eu mesmo meus trecos. Bom, ele foi desenvolvido para Netbooks e como o nome já diz é apenas um remix do próprio Ubuntu. Mas é uma distribuição oficial que você pode encontrar para Download no site da Canonical ou então pedir uma copia pelos correios, chega na sua casa em média 20 dias após solicitado, mas agora que os pedidos estão em alta pode demorar mais de um mês.

Escolhidos os sistemas operacionais vamos à pratica. Fatiar o HD, e instalar os dois sistemas.

Noob Tip Alert!!

Rule of thumb before you dual boot two Operating Systems: install the older OS first in the first and primary partition and create another partition for the other OS. For instance install windows XP first in drive C: , you may allocate another drive for your data that is D: and install the latest OS on E:/ Make sure that the last partition is big enough for the new OS. If, for some reasons you did all these the other way around, you may.. but try not to resort to those easyBCD and Dual Boot Pro, they might be problematic in the future. If you’re techy enough, might also try installing GRUB or virtual OS.. but why bother? Fresh install!! The above mentioned set-up is still the most advisable =) Good Luck! avoid disaster!

I’ve installed Ubuntu several times on various machines in a dual-boot format, but I’ve never blogged about it. In all cases, it’s been with Windows on the first partition (mostly with XP, but also once with Vista on a new machine), so I’ll use that as my example here.

First things first. Get Windows ready. This usually includes defragmenting to get all your files at the beginning of the partition. That’s pretty much it.

Next, get the install CD (from Ubuntu or your favorite distribution).

Boot into the installation CD. Ubuntu comes with a partition editor (GParted) on the CD, which you’ll need soon.

Resize your Windows partition in order to leave enough space for (a) the linux system itself, (b) a swap partition if your RAM isn’t plentiful, and (c) any other shared partitions you may want to make:

• (a) In the case of Ubuntu, the minimum hard drive space required is 4 GB, although in my experience at least 10-15 GB is better. This partition will probably be of type ext4 (at least, it is in the latest version of Ubuntu)
• (b) Depending on how much RAM you have and how much hard disk space is available, you may want to add a swap partition. This is a sort of paging file used to swap out segments of the RAM that aren’t used very often, freeing up memory for more active applications. On my old machine, which has 512 MB RAM, I added a 1 GB swap partition. On my current machine with 4 GB RAM, I don’t have any swap space at all and everything runs fine. It’s up to you.
• (c) If you want to be able to share files between Windows and linux (and haven’t yet converted to a cooler solution like Dropbox), it might be wise to make a FAT32 partition that can be read by both operating systems. Make this one however large you need.

Be sure to tell the partition editor that you’re going to want to put the root file system (/) on your ext4 partition, and ensure that your swap partition (if you made one) is correctly identified as such.

If you’ve made it this far, you’re almost done. Now run the installer and let it work its magic.

Ubuntu’s always installed GRUB without a hitch. But if you do run into trouble, this documentation from Ubuntu is a good place to look.

Congratulations, and welcome to linux!

I recently blogged about carrying out a dual-boot install of Windows 7 Ultimate on my personal desktop PC.

My current setup is Windows XP Professional on a 75GB HD and now Windows 7 Ultimate running on a separate 75GB HD. I realise it’s probably overkill having such large disks used for operating systems but I got a good deal on HD’s when I built the PC…so what the heck!

Why dual-boot?

I wasn’t sure how good Windows 7 would be (let’s face it, if Vista was anything to go by then I would be switching back to XP pretty soon) and I was happy with what I was getting from XP so rather than replace XP I wanted to be able to try the new OS and check all the hype from myself. So if like me you want to ‘test’ before you switch then carefully follow the instructions below.

How to set up

I already had Windows XP installed which makes the process easier but there are other people who have blogged on how to install XP on a system already running Windows 7 or Vista.

1. First things first, make sure the HD (hard drive) you want to install Windows 7 on has been formatted. The easiest way to do this is to open My Computer > Right click the drive you wish to format > Choose ‘Format’. Ensure you carry out full formatting process and not quick format.

2. Next step is to place the Windows 7 boot CD/DVD in the PC’s CD/DVD drive.

3. Now restart your PC.

4. Enter the BIOS menu by pressing the appropriate F key on your keyboard. For me this was F10.

5. The Boot menu should now appear (blue screen). Choose to boot from your CD/DVD drive.

6. Now carefully follow the instructions on-screen.

7. When you are prompted to choose ‘type of installation’, ensure you choose ‘Custom’ and choose the correct drive you wish to install Windows 7 to. Always double-check because the last thing you’d want is to overwrite your Windows XP installation.

8. Carefully follow the instructions on-screen until installation is complete.

9. When you restart your PC you will notice that you will be prompted to either use ‘Windows 7′ or ‘Previous version of Windows’. We have dual-boot mode…woohoo!

That wasn’t so hard now was it!

Go get a cup of tea and enjoy being able to dual-boot Windows XP and Windows 7.

Just installed Windows 7 Ultimate on my desktop PC. So far so good. I was a bit at first reluctant due to Microsoft’s previous OS release and to be honest XP did exactly what I wanted so why change, right?  A few colleagues who had installed Vista and changed over to Windows 7 said that the new OS was much much better and highly recommended the switch. Having not previously installed Vista for the reasons they changed to 7, I thought I’d better install Windows 7 on a new partition/hard drive… just incase it wasn’t as good as the hype.

So far I’m impressed. Everything seems to be working OK, no performance issues and was pretty quick to install. It also managed to download and install all the hardware drivers for me which was very handy.

Dual boot

I decided to install Windows 7 on a second 75GB hard drive (as I had a second spare HD sitting in my PC) and still have XP on a seperate HD.

I will blog about how I did this later.

Because Windows 7 has been giving me so much pain in the past 8 days I will now install Ubuntu Karmic Koala alongside the ailing Windows 7 installation. The intention is to create a second partition on the same harddisk and use that to install Ubuntu. I’ve done it before, what could go wrong. (Famous last words).

Just to be safe I have backed up all my data to an external disk and my PowerMac G5. Karmic is currently downloading and in 10 minutes I will be ready to break my world once again.

So from previous experience this should be pretty straightforward. Stick in the CD, boot into Ubuntu, run the installer and presto! A new OS. There are a few unknowns though.

Will Ubuntu understand the Windows 7 64bit filesystem? I know, it should know. After all it worked with Vista and what has changed, really? I guess we’ll see.

Also, is the bootloader going to be able to work out how to call the two OS-es. Same applies here. We’ll find out. More tomorrow. I’m going to the pub!

Just a quick techy post.

I was setting up Windows 7 on my laptop, which trashed access to the existing Linux Ubuntu installation on the machine (as any Windows install will do).  By the way – if you want to install Windows 7 on a free partition to dual boot, its possible, but I had to make the free partition ‘active’ to make Windows recognise it as a ’system’ partition … but I digress.

Anyway, I followed the instructions in this post – http://ubuntuforums.org/showthread.php?t=224351 – to restore the boot loader (Grub) and get Linux booting again, but then had to add an entry to allow me to select the new Windows installation.

Well, again I was able to use the usual way you get another non-Linux OS running within Grub, and there are loads of resources on the Internet to tell you how to do this.

For me it was an entry like this in menu.lst:

title          Windows 7
rootnoverify   (hd0,1)
makeactive
chainloader    +1

But I was getting the error “Invalid or Unsupported Executable Format”.  After quite a bit of searching around, with lots of varied responses to this particular error, I just couldn’t see what was wrong.

Then, after staring at the grub configuration for quite a long time, eventually I realised that the rootnoverify command had no space between the rootnoverify and the brackets – i.e. “rootnoverify(hd0,1)” … after adding a space, as shown above, all was well.

This post is just in case someone else has the same problem, and to remind them that before they start trying all the variants of grub commands and partition numbers that the Internet serves up in response to that error, do check the exact syntax of the menu.lst file first!

How to Survive Boot Camp (and Run Win 7 on a Mac)

Windows 7 and Snow Leopard are great. And cheap. Boot Camp’s the free, official way to run them both natively on one machine. It’s easy to setup, and just works, except when it doesn’t. Here’s how to survive Boot Camp.

Boot Camp, to be clear, is different from virtualization software like Parallels or VM Ware Fusion or Virtual Box, which you let you run Windows inside of OS X, almost like an application. Boot Camp runs Windows natively on a Mac—you power on, click the Windows icon at the boot manager, and it starts it up, just the same as if you’d powered on a Dell. Why Windows straight up on a Mac? To live a little. Or in my case, to play PC games.

What you’ll need

• A Windows 7 disc
• A Snow Leopard disc
• An Intel-based Mac
• Free disc space!

More on system requirements here.

It’s easy, probably

Boot Camp, and the process of installing Windows in most cases, couldn’t be more straightforward, at least as far as operating system installs usually go. After you’ve got your Mac up and running like normal, fire up an app called Boot Camp Assistant (just use Spotlight). It’ll warn you to back up your disk before installing Windows, which you should, since you are asking favors of the hard drive gods here.

Boot Camp Assistant will ask how much of your hard drive you wanna dedicate to Windows. You want more than the laughably small 5GB of space it suggests. Since I keep around 3-4 games on my Windows partition at a time, and I want some breathing room just in case, I stick with 40GB, but you probably really want no less than 20GB. Slide the bar toward the Finder face, granting Windows how much hard drive space you want it to have. After you click partition, Boot Camp Assistant will start getting your hard drive divvied up for some Windows action, which’ll take a few minutes. Once that’s done, you’ll need your Windows disk.

If everything went according to plan, skip this next section!

If something went wrong

It’s possible you’ll get an error that says Boot Camp Assistant wasn’t able to create the partition because some files couldn’t be moved, and you need to format the drive into a single partition. Basically, what’s happened here, most likely, is that your hard drive is fragmented like a mofo, and there’s not enough contiguous space for Boot Camp Assistant to create the Windows partition. Yeah, disk fragmentation. In OS X. Believe it. From here, there a couple possible solutions.

If you’re extraordinarily lucky, it’s possible you might be able to simply restart your computer and stuff will just work. Probably not! From there, you proceed to the free and easy solution. Using Disk Utility, resize your main OS X partition, reducing it by 40GB (or however much you plan on making your Windows partition). Hit apply, and pray. If that goes peachy, you’ll have 40GB of unused space on your disk. Go back to Disk Utility, and re-expand your OS X partition to reclaim the 40GB. After that’s all done, run Boot Camp Assistant again, and since the hard work of moving files around on the disk was done by Disk Utility, you should be golden.

If, on the other hand, Disk Utility also refused to change your drive’s partitions, you have two choices. The nuclear option is to back up, format your hard drive completely, then run Boot Camp and divide your hard drive into partitions from the Snow Leopard installation before restoring all of your OS X data via machine. Since my Snow Leopard install was practically virginal, as a totally clean (not restored) install that was only around 10 days old [ed. note—how the hell did your hard drive get so fragmented then?], I said screw that. Which led me to iDefrag.

It’s a $30 defragmenting program. I don’t know if my hard drive was really as disgustingly fragmented as it said, or if it’ll ultimately help my Mac’s performance, but it perfectly executed what I bought it for. Basically, you make a startup DVD (using your Snow Leopard install disc, so keep it handy), boot into it, and it shows you how gross and fragmented your hard drive is before going to work defragging it for a couple hours. Restart, you’re back in OS X, and Boot Camp Assistant won’t talk back to you again. At least, it didn’t to me.

The part where you actually install Windows, so grab some tea

Okay, welcome back, people without problems. After the partioning is successful, Boot Camp Assistant will ask you to pop in your Windows disc. If you’ve got one of these Macs and 4GB of RAM, you should install the 64-bit version. If not, go 32-bit. Now, all of the pains and glories of installing Windows will actually commence.

After you pick the language and accept the terms, it’ll ask you want kind of Windows installation you want. Pick custom, and you should get a list of hard drives to install Windows on. Make sure you highlight the correct partition and click format, which will transform it to Windows’ native NTFS file system, if you’re doing a partition that’s bigger than 32GB for Windows. Then tell Windows to install itself there. Go make a drink, and come back 20 minutes later.

Welcome to Windows land.

Now what?

To pick between booting into OS X or Windows when you turn on your Mac, start holding down the Alt key before the gray screen appears when you power on. (You gotta be fast.) It’ll give you the option to boot into Mac or Windows. Pick Windows, obviously. Once you’re totally in Windows, like with the desktop and everything, you need to pop in the Snow Leopard installation disc, and run the Boot Camp installer, which puts in place all the drivers Windows needs to actually run decent on your Mac.

After that, you should run Windows Update to grab the latest goods from Microsoft, and I’d suggest, especially if you’re running a unibody MacBook (or Pro) going to Nvidia’s site and downloading their latest Windows 7 drivers for your graphics card (the 9M series for unibody MacBook Pros, 8M for the previous, non-unibody generation).

Overall, Boot Camp 3.0 in Snow Leopard works way better and more smoothly than before: Multitouch trackpads on MacBooks feel way less janky; shortcut keys, like for brightness or volume, work exactly like in OS X (before, you pressed the function key); and you can read your OS X partition’s files from Windows now. (Back in OS X, you won’t be able to write to your Windows partition if it’s the NTFS format.) By the way, the command key, by default, is mapped as the Windows key, so you’re probably gonna annoyingly bring up the start menu a whole bunch. It’s natural.

Interesting.  Another hackintosh project.  Click here.

At the request of a friend, I met a friend of hers who had just purchased a new Apple iMac computer.  She was concerned about getting a program written for Windows to work on the Mac.  We investigated several options, and I told her that I considered the best one to be a dual-boot system, where the computer can boot up into either of two operating systems, thus allowing her to run Windows when she wanted to use her specialized software.

Come to find out, Apple has included that option in their new operating system, ‘Snow Leopard’.  It will automatically divide the hard disc drive into two virtual disc drives, and then allow you to install your Windows disc on the other one.  This is astonishingly mature  for a company in such a cut throat industry as Apple is.  But they have recognized that Windows users want to be able to enjoy the benefits of running a Mac, without having to sacrifice the advantages that come from using the operating system that almost all applications are written for.

This method allows the Mac user to enjoy the incredible design of these new computers, while still being able to run proprietary software for Windows.  And I have never seen a Windows machine like this!  It is beautiful, functional, and easy.  It is also probably very expensive.  But, if I had the money, I would certainly buy one!
