I have Windows Server 2003 and Linux installed on one hard drive [on separate partitions]. My first partition is the linux boot partition, and maintains Grub. When I boot the Windows partition and shut down W2k3 keeps modifying the MBR to boot directly, and only to the Windows partition. How do I prevent this behavior? I rather like using Grub to make boot selections.

This site does offer help with OS related issues (as seen by the tags) – monksy May 28 '09 at 2:26
@steven. Please post your grub.conf plaese – Alex Bolotov Jun 13 '09 at 18:46

Try to nstall GRUB on the first sector of the /boot partition, not in the MBR.

Then you can copy GRUB's boot sector into a file in windows, and add it to the Windows boot menu. – Peter Cordes Dec 10 '09 at 4:59

This was fixed because the "makeactive" option was enabled for the Windows 2k3 option. Taking out that option fixed the issue and still boots windows.

Perhaps the motherboard has the "boot sector virus protection" option?

Nope. Windows 2003 changes the MBR in fdisk. – monksy May 28 '09 at 2:25
