No, you do not want to use *, you want to use . Remember that the shell expands "*" and you will be at the mercy of whatever happens to exist in that directory. Using * you will miss all "dot" files. Here's the command you want: tar czf /otherdisk/boot.tar.gz . > 5. mount /dev/sda3 /mnt/root > 6. cd /mnt/root > 7. tar czf /otherdisk/root.tar.gz * Same as above, use "." not "*". > Restore; > 1.

Yeah, probably, but most times it's just as easy to just delete them after you've restored them. You're still booted from the CD after all.... > 12. chroot /mnt/boot > 13. grub-install --no-floppy /dev/sda > 14. reboot In the perfect world, you'll be running fine from here. Let us know how reality compares, though!
