It seems Fedora 7.0 has some problems with other operating system. We set up XP loader to load Fedora, sometime Fedora can't boot, just print GRUB and stopped, I have to reboot with CDROM in rescue mode and reinstall GRUB and then generate the file for XP to use.
The problem is in that condition 'modprobe fuse' will failed, so I can't generate the file directly to XP partition, I have to use network to copy the file out, and reboot XP and replace the file, and reboot to choose Fedora again.
