I have Ubuntu 12.04 as my main OS, but have been thinking of doing some dualbooting, would making a partition specifically for Windows and installing it to that partition mess with GRUB? or Would it be fine?

1st option : get a CD including Boot-Repair

The easiest way to use Boot-Repair is to burn one of the following CDs and boot on it.

  • Boot-Repair-Disk is a CD starting Boot-Repair automatically. (English only).
  • Boot-Repair is also included in Ubuntu Secured Remix CDs (multi-languages).

Get boot-repair disk

Remarks:

  • You can also install the ISO on a live-USB.
  • Please note that this ISO is not an official Ubuntu image.

2nd option : install Boot-Repair in Ubuntu

Either add ppa:yannubuntu/boot-repair to your Software Sources via the Software Centre or, for speeds-sake, add it using a new Terminal session:

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

You can run this from terminal sudo boot-repair

NO, just repair the GRUB –  Ringtail Mar 6 '12 at 4:34
    
So it wont touch Ubuntu itsself? just the GRUB loader then? –  Alex Poulos Mar 6 '12 at 4:47

I read that, I just need to know if because it touches the GRUB that it ONLY touches the GRUB not the 12.04 –  Alex Poulos Mar 6 '12 at 6:20

Yes, it will mess it up, but...

If you install Windows 7 / Windows XP, installer will override MBR to point to windows boot menu -- which by the way don't allow you to boot linux.

If you boot some live distro from flashdisk/CD/DVD after succesfull windows install and update GRUB (and edit grub.cfg to point to windows partition) you will be good again.

Note that Windows 8 beta behaves little differently.

Windows would mess up GRUB, after you install Windows just use a live CD and follow these instructions.

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  WarriorIng64 Mar 6 '12 at 9:46
