Moving from VirtualBox to read HDD and lilo

e-San · 09-09-2019, 04:40 AM

Hi!

I've been messing around with BasicLinux to prepare it to work on my 486 system. Long-story-short: I have 16MB working (converted from VDI to RAW) disk image which I've dd'ed on sda (on other system). Now LILO won't boot. Throws LI or hangs on LI or L 01 04 depends on system.

I thougt "Easy, just repair LILO!". So I booted, kubuntu 18.03 x86, then Ubuntu server and at the end BG-rescue-7.0. Every one boots, I mount (bind) /dev on /mnt/dev and try to run lilo, but it dies with "Out of memory".

Please help, I have no idea anymore...

boot your live disk

mount sda1 and rbind mount dev proc and sys and then chroot

Code:

mount /dev/sda1 /mnt
for i in dev proc sys;do
 mount --rbind /${i} /mnt/${i}
done
chroot /mnt

edit lilo.conf to point at sda
run/install lilo

I suppose the live disk might be consuming the available ram
so you may need a live env. with a smaller footprint

I did mount with -o bind and --bind those directories, but no luck.
I was forcing lilo (without editing lilo.conf) to write to /dev/sda by "-b" swich.

It is impossible that live disk is to big - bg-rescue should work on less than 100MB and I have 512MB.

Fortunately, I've found workaround: put "linear" into lilo.conf on my virtual machine and reinstall lilo. Now it boots fine after putting image on real hdd.

Thanks!
