the problem is getting serious
well... i've booted with the the cd you told me... i've tried to delete the grub but it said that i must select the previous os.... but there was only the line "sys linux" i've pressed enter anyway then i've rebooted again my pc... and now... ehm... keyboard doesn't work and then appears
boot from cd: (and after a while.. )
boot from cd:
but i can't do anything... as i've written before: keyboard is working no more, with or without cd in the drive nothing changes... even with floppy in "a:" nothing changes.... i think the pc's gone ...
