* Boot up your computer using Microsoft Windows Vista Bootable disk. (Check your BIOS setup)
* When you see the 1st Windows Vista installation screen appear, please configure your 'language' preferences.
* When prompted, click 'Repair your computer'.
* Startup Repair will automatically detect a problem. When prompted, click 'Repair and restart', and then restart your computer from the Windows Vista bootable disk. If Startup Repair does not automatically detect a problem, continue to the next step.
* click 'Repair Your Computer'.
* Click Command Prompt from the System Recovery Options.
* BootRec.exe provides the following command-line options:

* /FixMbr. Re-writes the master boot record (MBR) of the system partition to start Windows Vista. This won’t overwrite the existing partition table.

* /FixBoot. Writes a boot sector onto the system partition to start Windows Vista.

* /ScanOs. Scans all disks for Windows Vista installations and displays them to you. Oddly, this didn’t work for me, even on a test system that was starting just fine.

* /RebuildBcd. Scans all disks for Windows Vista installations and prompts you to pick the ones you want to add to the BCD.

* Type 'BootRec.exe /fixmbr' and press Enter.
* Congratulations! You're done.

Basically your Linux GRUB will go away. We recommend you look at GUID Partition Table.
