ran grub-install, no longer sure how to boot windows

Golovko · 07-21-2003, 07:41 PM

I have one drive, split in half, first half is NTFS (win2k) and second is my linux + swap. I ran grub-install /dev/hda1, wanting to remove the windows boot loader, now grub loads first (before the windows boot loader did), but I can't load windows. I have 3 other kernels that load fine.

I've tried this from a similiar thread:

rootnoverify (hd0,0)
makeactive
chainloader (hd0,0)+1
boot

but that doesn't work.

I've read how Windows likes to be first on the drive, and about using these commands:

map (hd0) (hd1)
map (hd1) (hd0)

But I don't think it matters since I only have one drive.

If anyone can point me in the right direction, much thanks.

More info:

my fdisk -l:

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1084 8707198+ 7 HPFS/NTFS
/dev/hda2 1085 2432 10827810 5 Extended
/dev/hda5 1085 2307 9823716 83 Linux
/dev/hda6 2308 2432 1004031 82 Linux swap

I ran grub-install /dev/hda1, which I am guessing was a mistake. I thought I could mirror my desktop machine config which loads grub first, then when I select DOS, loads windows2k.

2 problems are that I don't have floppy (laptop) and have no idea how to boot windows to where I can run fdisk /fixmbr?

Any tips? I guess the problem is I overwrote the first sectort on /dev/hda1 with grub? Is there any way to fix this within Linux?

If you want to install GRUB in the MBR:

Code:

grub-install /dev/hda

To boot windows2000 from GRUB:

Code:

title Windows2000
rootnoverify (hd0,0)
chainloader +1

Yes I know how to do that. My problem is I am pretty sure I typed "grub-install /dev/hda1", which I would believe overwrote the neccesary info on the win2k partition (/dev/hda1) to boot itself. Is there any way to fix this?

With the Windows2000 CD, you could try to boot it and use the Repair System option.
Although I don't remember if the win2k CD has the option, it should.

Once done, you use the RedHat 9.0 CD to boot into Rescue mode and re-install GRUB back into the MBR.

more specifically with the 2000 cd go into the recovery console. type "fixboot" and then type "fixmbr" and then do what mathieu said. :-)

Thanks for the help.

After booting with my laptop's win2k CD (a normal win2k pro cd wouldn't work for some reason), I went to the recovery console and ran fboot which then wrote to boot sector of c:

I didn't run fixmbr because I figured then it would be untouched and grub would run fine. However GRUB froze after printing GRUB. I booted up with my Knoppix cd and ran grub-install to /dev/hda and now I'm set up.

Thanks
