How to boot Ubuntu 14.04 with grub4dos (RMPrepUSB)

rated 0 times [ 2] [ 0] / answers: 1 / hits: 23866 / 3 Years ago, tue, november 2, 2021, 3:24:53

After downloading Ubuntu 14.04, I would run it from a bootable USB stick.

I already have the bootable USB stick with grub4dos, and I was looking for a 'guide post' with the command to boot Ubuntu 14.04. But I do not found.

My linux.lst (called by menu.lst) contains:

title Run Ubuntu 14.04

find --set-root /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso

map /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso (0xff) || map --mem /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso (0xff)

map --hook

root (0xff)

kernel /casper/vmlinuz.efi  file=/cdrom/ubuntu.seed noprompt boot=casper iso-scan/filename=/BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso quiet splash --

initrd /casper/initrd.lz

Error at Grub console:

Error 15: File not found

Why it not works? What is wrong?

Thnk you all.

Looking for a solution, I finally found the error and the correct code to boot it (it still works for me):

title Run Ubuntu 14.04

find --set-root /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso

map /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso (0xff) || map --mem /BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso (0xff)

map --hook

root (0xff)

kernel /casper/vmlinuz.efi  file=/preseed/ubuntu.seed noprompt boot=casper iso-scan/filename=/BOOT/Linux/ubuntu-14.04.1-desktop-amd64.iso quiet splash --

initrd /casper/initrd.lz

The mistake was the path to ubuntu.seed. The correct path is /preseed (rather than /cdrom).

Notes:

It had not worked with an Ubuntu 12.04 (non-LTS) that I had here.

Do not forget to change the path "/BOOT/Linux/ubuntu14.04.iso" to the path where your "ISO" file actually is.
