If you have grub in the mbr but you had gotten your grub.conf corrupted then you will need to re-write that file either from a backup that you took (and you always keep backups for this eventuality?) - or write grub stanzas as necessary to pull in the necessary OS'es you have on your system with their initial ramdisk files under /boot/ If you are a grub2 user then you will need to look at the grub2 documentation. Hopefully you only needed to re-install grub into the mbr on the drive! -- mike c _______________________________________________ York mailing list [email protected] https://mailman.lug.org.uk/mailman/listinfo/york
