Grub accidental install onto partitions. Windows no longer booting. Possible restore?


So, like the title says, I made the newbie mistake of accidentally doing the auto grub install. It looks like it wrote over a few drives and windows will no longer run even with the special commands. Is there any way to delete and restore what grub wrote over? My options are limited as access to another device is limited and I haven't used linux enough to set it up with a working gui. Thanks, time is of the essence..

You haven't stated which linux version OR which Windows version, that you are using . . .

however:- if you are using Win_XP:-
1. First, restart your computer with the Windows XP setup disk in the CD drive.
2. When prompted, boot from the CD drive by pressing any key.
3. Once the setup loads, you will see the option to press R to repair a Windows installation.
4. Once the Recovery Console loads up, you will have to type in a number that corresponds to your Windows installation. This is normally just 1. Press Enter and then type in the Administrator password.
5. Now at the prompt, type in fixmbr. Your damaged MBR will now be replaced with a new master boot record and your computer should now be able to boot properly.

You can use something like smart bootmanager to boot the windo$e,you can find it on UBCD,if you rewrite the MBR with just about any utility that does that,it will restore the windo$e MBR,then after that you can reinstall GRUB to get access to your Linux system.

Google for UBCD and make sure to get the free one.

Talking Smart bootmanager can boot a system with a bust BIOS

Not sure of hughetorrance' triple post but I can assure you that pierre2's instructions for XP will restore the bootability of XP.
