    In rare cases, Windows OS installation disk doesn't boot up because of GRUB. It looks like you are facing similar problem. You have to remove GRUB from MBR.

    Do you want to keep Linux Mint and setup dual boot or just wipe Hard disk and install Windows OS only?

    In any case, post the output of sudo fdisk -l command here.
    Code:
    sudo fdisk -l
    * Its small L in fdisk -l.
    It is amazing what you can accomplish if you do not care who gets the credit.

    I'm guessing Caspar, that GRUB has overwritten the MBR? For XP, boot to windows install CD, select recovery console, select your windows install, and run 'fixmbr'....

    no, i'm using linux mint 10 i think. i tryed booting with vista disk from disk drive but it simply prompted to the login menu.

    i keep getting suggestions to delete the os from terminal but i don't know the procedures to do that.

    what i need is specific instruction.

    It means Machine is not even trying to boot up from Vista Disk. Have you checked BIOS settings? Make sure to set DVD/CD drive as first boot device in Boot Order options.

    As I mentioned in my last post, we need output of fdisk -l command first. We will post instructions after looking into output of fdisk -l command only.

    I've just had to do this on a number of computers that had their hard drives wiped clean (donated to the school by a business)
    Boot from a live Linux CD/DVD (e.g. Knoppix or GParted) and open a console and run
    ms-sys --mbr /dev/sda
    (assuming your hard drive is sda)
    That will replace the GRUB bootloader with the Microsoft bootloader on the MBR (Master Boot Record)
    Now it should boot into your Windows partition.

    In case you want to wipe Hard disk, execute following command in Mint's Terminal :
    Code:
    sudo dd if=/dev/zero of=/dev/sda bs=512 count=1
    Reboot machine.

    Above command will remove Partition Table and Boot Loader. Your Hard disk will be blank as new one.
