Hello,
I needed to install Windows XP on a logical partition, but I found that it
can't boot from such a partition because NTLDR needs to be installed on a
primary one.
So I set up the following partition scheme:
  /dev/sda1 ext3 Gentoo root
  /dev/sda2 ntfs NTLDR
  /dev/sda4 Extended
    /dev/sda5 ext2 Gentoo portage
    /dev/sda6 swap Gentoo swap
    /dev/sda7 ext3 Gentoo home
    /dev/sda8 ntfs Windows XP

Win xp installed and booted without problem but now that I need to restore
GRUB, I am wondering if I need to write "root (hd0,1)" or "root (hd0,7)"
into the grub.conf to boot windows.

Thanks for your help
Julien.
