The boot flag should be on the partition where you have installed lilo (boot=/dev/hd??), unless you have put lilo on the MBR (the Master Boot Record -- probably on /dev/hda, except newer BIOSes can be configured to point elsewhere), in which case the boot flag is irrelevant. If you have had lilo on /dev/hda at any time in the past, you cannot change to, say, the root or /boot partition (which is usually where one would expect it, _not_ on drive hdb), until you first restore the original dos style MBR. The original MBR can then honor your boot flag, so that your lilo install on another partition can work. If this seems to be the source of the problem, the easiest way out is probably to just go with lilo on the MBR, by making sure you have in the global options: boot = /dev/hda and rerun lilo. Alternatively, you can put the MBR back, by running the MS-DOS fdisk with the /mbr switch (be very careful): fdisk /mbr Lilo also tries to backup the MBR, and there is a lilo option to restore it, if the original backup file is still there. If the above doesn't help, you may need to run lilo very verbosely in the test mode and carefully inspect the output: lilo -t -v -v -v > lilo.test.output less lilo.test.output Three -v options is probably about all you can stand, or would need, and two might be enough, and a lot less messy. Lilo won't actually change anything in test (-t) mode, so you can make as many tests as you want, till you're satisfied, then remove the -t and extra -v options to actually write the disk. > I've also used map-drive to switch the drives, but it still > won't boot.
