Stopping Ntldr From Installing

[amp_man]

Hey, I'm looking to reinstall windows on my computer, but I'm dual-booting ubuntu (a debian based linux distro). I'd like to stop NTLDR from loading into the mbr so I don't have to reinstall grub afterwards, but I'm not sure how to do this, and my laptop doesn't have a "boot sector virus protection" option in the bios. Any suggestions? Thanks

as far as i know ntldr is ESSENTIAL for windows to run

Actually NTLDR is not loaded into the MBR, it is referred to in the MBR.

So all you have to do is save your MBR (already containing the modified GRUB MBR) to a file, install whatever you like, then restore the MBR from file.

Be warned that if you change your partitions in the meantime this procedure won't obviously work.

You can use MBRwizard (both from DOS and Win32):

or from Linux dd
