Switching to LILO from Grub

Well, here is problem on computer number one. I used to be a fairly hard-core devotee of Linux in the early 90s (kernel numbers < 1.0) but having not used UNIX of any sort in about 8 years, seem to be struggling with just about everything.

After hearing all this hoopla over Redhat, I installed Redhat, only to decide that Redhat _sucks_, if for no other reason than that those little redhat wearing fools thought they were being clever by violating every single UNIX convention ever _written_.

Back to slackware for me.

So, I did a couple of things:

Added a new hard drive, as, /dev/hda. (hda1 is /root, hda2 is swap)
Old hard drive was reformatted and mounted to /home as /dev/hdb1.

After slackware v10.0 install, I can boot from a floppy fine, but cannot boot from the hard drive. All that happens is grub comes up as "Grub" and the system hangs. So, I guess the brilliant boys at Red Hat wrote Grub into the MBR of /dev/hdb.

Why my computer boots to that, I don't know, but I think that is what's happening. I've installed LILO to /dev/hda (correctly, I think) but it just isn't happening.

Does anyone know how to fix this? My thinking is I need to clear the MBR on /dev/hdb (am not quite sure how to do this) and then install LILO to /dev/hda (but I think that's already done.)

Any advice and/or insight is appreciated.

I would make sure that boot sequence is ok in the bios.
If it fails, I would attempt to erase mbr from /dev/hdb like :

dd if=/dev/zero of=/dev/hdb count=1 bs=426 && sync

But before that, if you have a prompt like this at boot :


...then you have the possibility to use grub as bootloader if you want.

something doesn't sound right. have you checked your BIOS, jumper settings, and cabling to make sure the hard drives are set up properly (master/slave on IDE1, master/master on IDE1/IDE2, etc.) ?

if that's okay, then what i would do is remove hdb, boot to hda, with the floppy disk if necessary, rerun lilo installing it to the MBR of hda, then shut down, add hdb again, and try to boot. once i was booted again with both drives, i would overhaul hdb just to clean everything off it. that should work, if not post back.

I don't think /dev/hdb MBR has anything to do with it. If your BIOS points to /dev/hda as the boot disk, /hdb MBR never even comes into play.

Rather, make sure your lilo was correctly set up in /etc/lilo.conf (post it if you dont mind.)

Thanks guys. It must have been something in the BIOS, I removed hdb, it booted fine, plugged hdb back in, it booted fine.


Is there a way to tell LILO to cut all the verbosity and just boot straight into Linux with no delay (and I don't really need the ugly LILO screen, either)?

you can change the delay to 0 if you do not want to see the lilo screen. the rest of the stuff is kernel booting. i like to keep an eye on that stuff to see if a problem leaps out at me.
