grub2 on livecd

qrange · 05-06-2011, 07:53 AM

is there a livecd with grub2?
I need an bootable .iso that starts latest version of grub2.

(debian and ubuntu livecd use some custom format, they don't have the grub2 menu)

Correct me if I'm wrong, but I'm not sure grub can work from a CD. It uses very little that cannot be provided by the BIOS to bootstrap itself, and AFAIK, it does not know about ISO-9660 filesystems. That is why ISO-Linux is the de-facto standard bootloader for live CDs.

Grub can boot CDs and has had that capacity for well over a decade. Most distributions use isolinux or syslinux. In Grub Legacy, the stage2_eltorito file was necessary to boot a CD. Grub2 can also but it's a little different. You can copy an iso file to a CD, install Grub2 on it and boot the iso file from the CD. You can also boot systems from a CD with Grub2. The only systems I have used this for were Puppy lupu and SystemrescueCD.

let me check if the iso he works with comes with grub2 ( i am not sure, checking that will take me a bit of time, half an hour or a bit more):
