Win7 Ubuntu 12.04 XP Dual-Disk 3 system grub Configuration

Disk 1:ubuntu12.04 Win7

Disk 2:XP

sudo update-grub results only Win7 and Ubuntu, click win7 into the system, see Win7 and xp,win7 can start, but XP cannot. So I found a grub file with someone else's XP and Ubuntu in the web search.

Found my missing a word, drivemap-s (hd0) ${root}, so plus on the OK.

That is, add the following content to the/boot/grub/grub.cfg

Menuentry "Windows XP"--class Windows--class os {

Insmod NTFS

Set root= ' (hd0,1) '

Search--no-floppy--fs-uuid--set=root 4c844b34844b2036

Drivemap-s (hd0) ${root}

Chainloader +1

}

Set root= (hd0,1), which represents the first partition of the No. 0 disk, where the hard drive number starts at 0 and the partition number starts at 1. My XP is in the No. 0 partition. My XP and Ubuntu are no longer the same disk, grub in Ubuntu is shown in HD1 so XP must be in hd0, while the system is in C: disk, so is the first partition

The entire grub file is as follows:

#

# Don't EDIT this FILE

#

# It is automatically generated by grub-mkconfig using templates

# FROM/ETC/GRUB.D and Settings From/etc/default/grub

#
