GRUB Error 13

I get an error 13 when trying to dual boot my Windows XP drive. I'm using a AMD64 box and two seperate SATA drives. XP is on the second drive but was installed while it was the first hard drive. This is my GRUB conf for XP.

title=Windows XP
map (hd0) (hd1) # Tell the first hard drive to pretend to be the second
map (hd1) (hd0) # Tell the second hard drive to pretend to be the first
root (hd1,0) # Tell GRUB Windows is on /dev/hdb1 (No pretending here)
rootnoverify (hd1,0) # GRUB won't attempt to mount the Windows drive
makeactive # Sets the partition to active
chainloader +1 # Tells GRUB to load the Windows bootloader when done

Seems to work for everyone else, but not me

Done a little more reading in the mean time and I tried chainloader (hd1,0)+1 with no success. No error message, it just displays the chainloader text and a few blank lines before hanging. Any ideas?

you seem to have the wrong binary format. did you compile your kernel with ELF support?

what does

I'll check, but I don't know why a kernel option would have any effect on GRUB?

I get CONFIG_BINFMT=y, so it's enabled.

What happens if you remove/comment out:

No, you need the root statement.
Any chance of a "mickey mouse" set-up partiton on that drive ???.
Try root(hd1,1)

I'll give that a shot.

Try removing rootnoverify (hd1,0). You only need rootnoverify or root, so see if removing either makes any difference.

Actually, it looks like the problem was with my copying it over from this computer.

I assumed that:

map(hd0)(hd1)

Was the same as:

map (hd0) (hd1)

Whitespace matters. Only figured this out after making some of the changes you all suggested and it changed the error from 13 to 11. Then I noticed that you could edit the conf file from within GRUB to experiment and finally got it.

The final working config is:

map (hd0) (hd1)
map (hd1) (hd0)
root (hd1,0)
rootnoverify (hd1,0)
makeactive
chainloader (hd1,0)+1

Whether or not you can delete some of that, I'm not sure. But it would be easy enough to experiment with the GRUB editor

Thanks!
