    Multi boot: selected disk does not exist

    Hi all!

    Currently I'm running 3 operating systems on my machine; Windows XP, Windows 7 and Fedora 14.
    I've installed them in the following order: XP -> Win7 -> Fedora14, with the idea that this would work fine regarding operating system selection at boot time.

    But unfortunately, I just installed Fedora, and now I'm unable to boot Windows 7/XP.
    When I select the "Other" option in the Grub menu, I get the following error:

    Code:
    Error 21: selected disk does not exist
    To provide as much info as possible, here is a boot info script log:

    Hi and Welcome !

    Edit Other block of /boot/grub/grub.conf file.

    Code:
    title Other
	rootnoverify (hd2,0)
	map (hd0) (hd2)
	map (hd2) (hd0)
        chainloader +1
    It is amazing what you can accomplish if you do not care who gets the credit.

    I've tried to re-setup grub... and even that doesn't solve the problem.

    Here is the outcome:

    Code:
    [root@localhost Thomas]# grub
Probing devices to guess BIOS drives. This may take a long time.


    GNU GRUB  version 0.97  (640K lower / 3072K upper memory)

 [ Minimal BASH-like line editing is supported.  For the first word, TAB
   lists possible command completions.  Anywhere else TAB lists the possible
   completions of a device/filename.]
grub> root (hd0,2)
root (hd0,2)
 Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0,2)
setup (hd0,2)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... yes
 Checking if "/grub/stage2" exists... yes
 Checking if "/grub/e2fs_stage1_5" exists... yes
 Running "embed /grub/e2fs_stage1_5 (hd0,2)"... failed (this is not fatal)
 Running "embed /grub/e2fs_stage1_5 (hd0,2)"... failed (this is not fatal)
 Running "install /grub/stage1 (hd0,2) /grub/stage2 p /grub/grub.conf "... succeeded
Done.
grub>
    Although it seems to have succeeded, the problem is still there.

    I'm out of ideas at this point...
