Grub's partition table handling doesn't reset itself properly when going from an "extended" DOS partition on a HDD to accessing a CD, and ends up trying to read from the CD at the same offset as the logical partition table was on the drive. :( Workarounds: - Don't use an extended partition to save the state directory. - Edit the boot commands to issue "root (hd0,0)" just before "root (cd)", which should unstick the partition table pointer. You'd have to do this on every boot, though. :( Thanks, Ian _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
