    Hi guys just a quick question on dual booting here.
    On my 500Gb hard drive I have Windows 7 and Ubuntu 9.04 on it.
    When ever i turn it on GRUB loads and allows me to select the OS i want to use.
    But I want to get rid of Ubuntu and install XP on it.
    When I was installing Ubuntu i didnt partition it before hand I just used the built in partitioner.
    And last night i was flicking through my Motherboards manual and i saw that there was a virtualization setting in the BIOS allowing you to run multiple OS's.
    At the moment that setting is disabled (By default).
    Now if I format the partition with Ubuntu on it,GRUB should be gone right?? So would i have to enable the setting in the BIOS to dual boot XP and 7???
    Thanks.:D

    Oh yeah my mobo is Gigabyte GA-MA790XT-UD4P

    it depend on a few things really, if you install xp it will probably make itself the only os you can boot to, if you then repair the windows 7 boot using the options on the install disk, it might then let you boot to windows 7 and xp. The motherboard setting might help you out but I would guess it might be for two seperate disks and not seperate partition.

    Mght be a good time to back up your data before messing around and doing a fresh install of the operating systems you want to keep might also be a quick solution if the disk and partitions are too messy to boot how you want

    That virtualisation setting has nothing to do with dual booting OS's. Id imagine that is to activate hardware based OS virtualisation for running a virtual operating system on top of your existing system. Eg if you wanted to install Microsoft Virtual Pc within win7 and install virtual xp you would need to enable that setting.

    Grub is installed to the MBR so it won't be gone if you format the Ubuntu partition.
    Best thing to do is reinstall xp to the space Ubuntu was using. That will install the XP bootloader over grub.

    As Ghost_Train said you will then have to repair windows 7 using the windows 7 installation disk. (If the auto boot repair dosen't work go to recovery console and type bootrec.exe /fixmbr). You should then be able to access xp and win7.
