I have a machine with Ubuntu 12.04 LTS Desktop installed and everything works find. I would like to install 10.04 LTS on a second partition.
As standard procedure, I tried booting from a 10.04 DVD through the BIOS. When the 10.04 disk is in the drive, it is not listed as a bootable device. Only my linux partition is listed as bootable drive. The DVD drive is listed as a bootable device with other distributions such as 13.04 and 13.10. My kernel version is Ubuntu 3.11.0-19.33~precise-generic 22.214.171.124. My grub version is 1.99-21buntun3.14.
