Comment 41 for bug 476625

I also have the same problem on a Packard Bell with Windows Vista, having just installed Ubuntu 10.10

### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Windows Vista (loader) (on /dev/sda1)" {
    insmod part_msdos
    insmod ntfs
    set root='(hd0,msdos1)'
    search --no-floppy --fs-uuid --set 64bce3a1bce36bcc
    chainloader +1
}
menuentry "Windows Recovery Environment (loader) (on /dev/sda2)" {
    insmod part_msdos
    insmod ntfs
    set root='(hd0,msdos2)'
    search --no-floppy --fs-uuid --set bc3c53c13c5374fc
    drivemap -s (hd0) ${root}
    chainloader +1
}
### END /etc/grub.d/30_os-prober ###

In reality, Vista is on sda2, Recovery is on sda1
