Contents

  • I want to boot my Linux without modifying my MBR.
  • I want to boot Windows by default but being able to boot my Linux in a hidden way.

Quick solution

  1. !LINUX! (1) AUTO
  2. SGD presents your grub boot menu again.

Not So Quick solution

  1. !LINUX! (>2) MANUAL
  2. Choose the partition where the Linux GRUB you want to boot is located.
  3. SGD presents your grub boot menu again.

Classical solution

  1. Choose the partition where the Linux GRUB you want to boot is located.


Advanced solution

Sometimes menu.lst is incorrect. Sometimes you are lucky and have some default links that point to vmlinuz and initrd.

  1. Choose whether your Kernel identifies your disk as SATA/SCSI or IDE..
  2. Choose the partition where the Linux Kernel you want to boot is located.
  3. Choose the partition where the Linux GRUB you want to boot is located.
  4. Linux might boot.

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.
