Giving boot-loaders the boot
Boot up blues...

I have successfully removed Mandrake 8.1 from a computer that needs "that other operating system" installed on it, but I can't seem to get rid of the boot loader.

I've removed all partitions from the drive, but lilo still attempts to run (and fails). Can anyone help?

Are you using FDISK to change the partition settings??

If so, you may need to use a utility which runs on the same OS as Mandrake. This is due to the incapability of FDISK to read non-dos partitions.

I do not know for sure if this is the problem, since I have no experience with Mandrake, but I have run into this same thing changing drives from an NTFS (Win NT) partition to a dos OS, FDISK (dos version) can not remove NTFS partitions. So, this may be a good thing to think about, try a different utility to remove the old partitions. (look for 'extended' non-dos partitions)

This comes up with any UNIX-like operating system.

Get to a DOS prompt somehow and type "fdisk /mbr".

That'll clear out the Master Boot Record so that McOperatingSystems are happy.

Thanks for the advice, it's very much appreciated.

I was indeed using a DOS version of FDisk, which it appears was not altering the MBR properly - Lilo was partly loading and then freezing the machine. Everything appears to be back to normal now.

For future reference, could either of you recommend a decent partition/format manager? I've got the Partition Magic 6.0 boot disk program - would this be sufficient in future, should I get the chance to revert back to Linux?

I've always just used the "pfdisk" that you can find at freebsd.org or netbsd.org
