Grub hdb2


Ok, I have a grub question. My linux is on hda1,2,3, and primary master (jumpers), and my windows xp is on a separate hard drive, hdb2, primary slave.

I edited the grub.conf file to include this as

rootnoverify (hd1,1) <- the 1,1 = second drive, and second partition, right?

well when I use it, it says it can't load that disk, it doesn't exist.

then i load linux, and it is mounted in /mnt/win automatically.

so what do I put in the rootnoverify deal with my above configuratioin?

I have changed it directly from grub to 1,0... 1,2... 0,2... no help.

thanks,

phil

Look at:
/boot/grub/device.map

This will tell you how the drives are refferenced.

Did you use map in your config?
title Windoze XP Pro
rootnoverify (hd1,1)
makeactive
map (hd0) (hd1)
map (hd1) (hd0)

I am no Windows expert but I think that Windows insists on being booted from the first disk.

i tried the map thing, and I think that I needed to do that, but it still won't work.

When I look at the /boot/device/grub.map it doesn't list the second hard drive at all. just hda...

Do I simply add hdb ?

thanks

phil

To make it easier for us to help you,
can you post the contents of grub.conf and device.map

Open a terminal (console) and type:
Code:
more /boot/grub/device.map
more /boot/grub/grub.conf

I still need help, if anyone can help...

My grub.conf, and my device.map are listed above, and my hard drive setup looks correct, but it says the drive doesn't exist when I try to boot to windows.

Thanks for any help.

I don't know if this will work, so don't quote me.
Try mapping the partitions.
Code:
title Windows XP
map (hd0,0)(hd1,1)
map (hd1,1)(hd0,0)
rootnoverify (hd1,1)
chainloader +1

Ok, thanks to all who helped, I succeeded. I tried many different options, and most of the editing was from the grub screen, not a text editor.. Then when I gave up, it said I had an error, so I re-booted, then when I selected XP it worked.

It has successfully booted back to RH9 (thank god!) but I have yet to check to see if it will again boot to XP.

here is my successful grub.conf

well I spoke too soon, apparently it worked that once, and no more.

I guess the edits I did from the grub program didn't save themselves, and they self-destructed when it loaded Windows. I have tried all configurations again, and cannot duplicate what worked.

The files above are still current, and don't work.

If anyone can help, let me know, please.

Is there a way to run the config again, so it will detect my set up by itself, like it would have done in the beginning if my windows hard drive was connected when I installed?

If not, is there anyone who has 2 drives, win xp on the slave, and what is your grub.conf???

thanks!

phil
