Boot “live-cd” linux distros from GRUB manually












1















I want to boot Linux distros from GRUB 2.0 command line. I've tried to do so for couple of distros and at "best" I receive initramfs prompt, no GUI which starts if distro is run stardard way.



vmlinux, initrd and filesystem.squashfs files are in casper folder and linux command in menu entry in grub.cnf in distros contains boot=casper, I suspect folder name casper is not necessary for kernel option to work, casper is persistence something option related as far as I understood from wikipedia.



Also as far as I understood the problem, when boot process tries to do unionfs thing it could not find SquashFS file with all except kernel distro stuff to add. How do I let it know its' location? Maybe the problem is of other root cause, please tell me so then.



ADDED 0: I changed linux command adding root=UUID=what ls command gives for partition with distro and
now starting, finally getting many lines stdin: Not a typewriter, then (initramfs) Unable to find a medium containing live file system and again CLI prompt. Was stdout on screen same lines as w/out root option... I just don't remember for sure, so many lines during boot.



ADDED 1: I run grep -rnw 'initrd file loop mounted location' -e 'filesystem.squashfs' as per https://stackoverflow.com/questions/16956810/how-do-i-find-all-files-containing-specific-text-on-linux and got nothing, so have no idea how init process finds that squashfs file.

  • Have you ensured that the vmlinux and initrd files are located by the grub console? If you type ls in the GRUB console, you should see the different disks and partitions; if you type ls (disk,partition)/casper, you see the files?

    @Dasel, yes I ran them and them boot, I got CLI, but not full Linux file structure from distro so as I've wrote my guess squashfs file was not merged. I also now added more details to question.
