Adding Live disk ISO to Grub2 ?

Post by Lucap »

Something i've been meaning to try for ages is adding Livedisk ISO's to grub and booting them from hardrive.

When you boot the ISO can you still access the HDD drive that it was booted from or is it locked out and hidden?

If that made any sense? :P

Iso isn't bootable from HDD. You have to install it to the HDD to boot.
When you boot from an installed iso, the disks are very much accessible.
If I have helped you solve a problem, please add [SOLVED] to your first post title, it helps other users looking for help.

I had used this, only mint and ubuntu official derivate

but it is in Italian, you can try and see if it does what you want

install the grml-rescueboot package and then copy the iso to the /boot/grml folder and run a grub update

https://forum.ubuntu-it.org/viewtopic.php?f=38&t=607698


if you want to install the distro on a partition (it could also be used to access other partitions, I've never tried this thing and I do not know if the other partitions are accessible or not)
sudo umount -l /isodevice

I have done this using this guide:
https://www.howtogeek.com/196933/how-to ... ard-drive/

But only on legacy BIOS system. I have not been successful (yet) doing this on an UEFI BIOS system. Probably just from
my lack of knowledge. But would be interested if anyone else was successful.

I have try now the steps with grml rescueboot like I said before, and it work, I'm writing now from a iso of ubuntu 17.10 copied in /boot/grml in my Mint installation and booted from grub, and the partitions of my installation of Mint is accessible and I can copied file on live system in use, or on a usb media.

I've decided if i want to play with anything i'll use the newly updated gnome boxes in the above link as i saves messing about with grub.

Thanks for the info all.
