One obvious solution not already mentioned is to back up the bootloader *in Linux* as a normal file, so the backup software can then just back it up like any other file. It's a simple enough workaround to the deficiencies in your backup software. dd if=dev/hda of=/boot/bootsector-backup bs=512 count=nnn Stick it in as a daily cron job and you're done. When it comes to restoring, you can just dd it back and you're in business. > As a personal advice, I would recommend you to stop bothering with that > broken backup software, it doesn’t seem good for your health.

The same software is likely also broken with GPT partition tables, BSD partition tables etc., so it's not like it's just grub at fault here! For the most part, grub is a vast improvement over LILO, and except for the odd corner cases which grub doesn't cover, grub is a much better choice if you have the choice. Regards, Roger -- .''`.
