I booted using the boot rescue mode. I found that the file grub.conf has a size of 0 byte :-( so it has been deleted. don't know why. I tried using a very old backup of a grub.conf file, to reboot, but my system says it can't boot. So I guess, but tell me if I'm wrong, I have to reinstall the boot loader. The pb is that I don't remember which hard disk it has been installed. fdisk -l gives me that : Disk /dev/hda : 40,0 GB, etc... Device Boot Start End Blocks Id System /dev/hda1 * 1 10 80293+ 83 Linux /dev/hda2 11 1285 etc.... Disk /dev/sda: 160,0 GB, etc... Device Boot Start End Blocks Id System /dev/sda1 * 1 19457 156288321 7 HPFS/NTFS How do I know where to install the Bootloader ? HDA or SDA ? The old backup, but ... I'm not sure this file comes from that system, said #boot=/dev/hda Thanks. Francois --
