Installed ubuntu but grub doesn't show my old windows install as an option


I have 3 SATA drives with 2 in raid0 which contains the windows7 installation I'm interested in, and the 3rd holding two versions of ubuntu (I think, I've lost track). There is also an IDE drive with windows xp.

Messing with BIOS settings I can select either the IDE drive or the raid0 to boot from. When I boot from the IDE I see the old ubuntu and windows xp in grub. When I boot from the raid0 I see two versions of ubuntu and windows xp but no windows7!

Here is the results of a boot info script someone suggested running...
Code:

 => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in 
    partition #6 for /boot/grub.

 => Grub 2 is installed in the MBR of /dev/sdd and looks for 
    (UUID=c7938c11-59ff-49c2-b44a-ea8b2b84352d)/boot/grub.

Other notes: From the new ubuntu install I'm not able to see the raid0 drive. Booting from the install CD, I'm able to see and mount the raid0 drive and browse its contents.

Any ideas?

Grub 2 is a disaster still, because it is so new... I'v spend daze wrestling with it, before I said enuff is enuff.. until they progress more. The docs are scant, and other information scattered over the net is either wrong, too complicated, or otherwise misleading.

The quick fix would be to trash it, put the old reliable grub (legacy)ver 0.97-61 back on.

The only thing to consider extra, because you have ext4 (I think on all your partitions).. is to put your /boot (ie. grub files, kernels, initrds, etc.) on a small separate ext3 partition, or grub (legacy) won't be able to read them.

Lettuce know..

Neither Grub Legacy nor Grub2 actually boot windows but simply point to the windows bootloader which then takes over. Your script output shows Grub2 in the mbr of sda and sdd and xp boot files in sdc.

xp by default is not capable of booting win 7. win 7 can boot xp. If you review your script output, you will see entries for xp in the grub.cfg file but none for win 7 which is the opposite of the way it should be with the windows bootloader capabilities.

I'm not familiar with Grub2 as it is still beta.
You will probably need to figure out some way to get win7 to boot xp and I expect you can search support.microsoft.com for an answer. Don't use either myself. I'm not sure what impact raid setup will have?

Try adding something like this to your grub.cfg
Code:
menuentry "Windows 7" {
  set root=(hd0,1)
  chainloader +1
}

Hi,

I've found the main problem with GRUB2 is the lack of documentation. It does seem to work well. The boot-loader doesn't know what isw_raid_member is. See: http://ubuntuforums.org/showthread.php?t=358120 and http://nil-techno.blogspot.com/2009/...-devsd-in.html . If you need help understanding those links, come back here and ask. But those should get you started.
