How to create a GRUB2 entry for a "LiveSD" Card

  • 772

I want to be able to boot any OS (this case: a Live version of Kubuntu) installed on a SD card (not USB).

I have followed the instructions given for a USB. However that won't work properly, the 40_custom GRUB2 entry that I have now is:

 #!/bin/sh
 exec tail -n +3 $0
 # This file provides an easy way to add custom menu entries.  Simply type the
 # menu entries you want to add after this comment.  Be careful not to change
 # the 'exec tail' line above.

  menuentry "PLEASE BOOT ME I AM THE SD CARD" {
       set root=(hd0,1)
       linux /vmlinuz root=/dev/sdb1 ro quiet splash
       initrd /initrd.img
 }

The option appears on the GRUB menu but whenever I selected it prompts the regular kubuntu splash screen and won't boot from my SD Card (or the HDD, either).

  1. As your USB stick comes up as sdb, the code should be:

    #!/bin/sh
 exec tail -n +3 $0
 # This file provides an easy way to add custom menu entries.  Simply type the
 # menu entries you want to add after this comment.  Be careful not to change
 # the 'exec tail' line above.
  menuentry "PLEASE BOOT ME I AM THE SD CARD" {
       set root=(sdb,1)
       linux /vmlinuz root=/dev/sdb1 ro quiet splash
       initrd /initrd.img
 }

    if the OS is installed in the first partition of the USB stick. ;-)
