I made the boot disk at the installation...is possible setup the place of lilo again? Because the system can be perfectly booted from a disk...
Is lilo.conf on the hard drive at all? - if so
to re-install LILO - su to Root user in an xterm - then
then save the file, then back in the xterm type
to reinstall LILO and the new map - and then try booting from the hard drive - make sure if youve been booting from a disk you change the BIOS to boot back from the hard drive again to test.
