Boot from CDROM

When booting on HDD, it is possible to tell Grub to boot from CDROM instead.

• Press esc to quit Grub GUI menu.
• Press c to go to command-line mode.
• Enter the following commands (adapt hd2 according to your configuration):

grub>rootnoverify (hd2)
grub>chainloader +1
grub>boot

Note that this might be actually a hack that only works on my machine. More information on normal way to tell Grub to boot on CDROM:
