Problematic solution

TODO EXPLAIN THE USE OF LIVESWAP WHEN DETECTED HARD DISK ORDER IS NOT OK.

Tecnical explanation

If you boot from a cdrom, floppy or usb you can always tell Grub to load your hard disk's menu.lst where all the information on how to boot your Linux is found. SGD makes this task an easy thing.

One thing you should know

• If your Linux filesystem has errors GRUB might not be able to find its files even if they are there. So sometimes is advised to try to run the:

fsck -yc /dev/DEV

command as root where DEV is your linux partition device.

fsck -yc /dev/sda3 

will fix the third partition from an scsi or sata first disk (Although it might not actually be the first one).

• If menu.lst is incorrect you will be able to access your menu.lst again but maybe Linux entries might not boot.
