Hello everyone. After hours of searching and more than likey screwing up my config file I've decided to ask for help.

I've got a laptop I use for various things. I have one SATA HD with a number of partitions on it. It looks like this.

sda2 = System Reserved (Flag=boot)
sda3 = Windows 7
sda4 = extended
sda5 = Ubuntu
sda6 = WinXP

I started off with Win7 on there and added Ubuntu. Everything went fine and Grub added Win7 and I could boot to both. Since then I had to add WinXP. That wiped out Grub which I read it would. I tried adding Grub back which was unsuccessful so I just reinstalled Ubuntu which re-installed Grub, but not Win7 doesn't boot from the menu when I select it. Since then I've been trying to add Win7 and WinXP back into Grub with zero success. In addition I add the following which did not work.

#! /bin/sh -e
echo “Adding Windows” >&2
cat << EOF
menuentry “Windows XP″ {
set root=(hd0,6)
chainloader +1
}
EOF

Could anyone walk me through fixing this up? Thanks all.

If you want xp and win 7, you should install xp first then win 7. The win 7 bootloader should recognize the xp and include an entry to boot it. The reverse is not true. It may be possible to boot win 7 from xp but it would be more difficult. You need Grub pointing to the win 7 bootloader partition which should then give you win 7 and xp options.

it should be (hd0,5)

check your entry for win7 too, I think you've entered it incorrectly in your grub.cfg file.

Thanks for all the replies. I'm still not able to get it. Here is my entire grub.cfg file. Any idea how to fix it?

Please place code in grub.cfg and other files inside [CODE] tags.

since you are using grub2, the mapping of hd starts from 1, so your entry for windows is fine.
You can run boot info script to see all the details about your boot and then check for any errors and post your output here.
