Question Grub boot loader removal

I installed Windows XP on one hard drive and Redhat Linux 8.0 on a second hard drive using the Grub dual boot loader. The dual boot worked fine, but then I wanted to remove Redhat from my PC. So, I formatted the second hard drive with Redhat on it from Windows XP. All seemed fine until I rebooted and now I can't boot up Windows XP properly. It looks like the Grub boot loader is on my drive with Windows XP and because it "can't find" Redhat it is "stuck". Can I remove the Grub boot loader and regain access to Windows XP without formatting my drive with Windows XP and reinstalling Windows XP?

If you have the XP CD cd run the recovery console and use the command fixmbr That will rewrite the master boot record for XP

What can you do if you have Win2k Pro? Grub just hangs you on boot.

Hello soelter, welcome to the forums.
The commands are the same for Win2K. If your CD isn't booting, make sure your BIOS is set to boot from CD before Hard disk.

grub commands

The grub interface itself is pretty powerful. If you've deleted it's configuration files, you can probably still manually configure it and boot regardless. If you have the "grub> " prompt, this should be possible.

An example is:
grub> root (hd0,0)
grub> chainloader +1
grub> boot
This says to look in the first partition of the first hard disk (hd0 == first IDE disk) for the next stage of the bootloader. If your Windows installation is on the 2nd partition of the first hard disk, it would obviously be (hd0,1).

Using XP's "fixmbr" to remove Grub

Unfortunately, "fixmbr" is only available in XP Professional
edition, not XP Home edition, which is what I have.
Any other way of removing Grub?

I have XP on one drive and Linux on another. I wish
to isolate the 2 OS's, having normal boot to XP and
booting Linux from CD.

Thanks for any help.

Bruce

Using XP's "fixmbr" to remove Grub - more

Forgot to mention that I have Knoppix. Could this
be of any help in removing Grub?

With knoppix you could re-install grub, but not remove grub. If you could get a DOS floppy, or even something like a windows 98 boot floppy, then you could run the FIXMBR command, since you say it is not in the XP Home edition.

Nope, FIXMBR is a standard part of XP recovery console for Home and Professional, not in Win9x.

Bruce, what makes you think fixmbr is not available on YOUR XP home recovery console?
Here is the official Microsoft word on the recovery console:

Ah, okay. I wasn't sure if it was in the 98 boot floppy or not, I don't use windows much. I know it is in the Win2k cd, though.

Yep, as posted back in October, XP and 2K both use fixmbr, Win9x (and ME) use the /mbr switch on fdisk.exe (i.e fdisk /mbr from a boot disk command prompt) which will not help in a 2K/XP environment (in fact will probably make things worse.
