As a general recommendations, check md5sum
- you need to compare both: first, the md5sum
of a downloaded file first.
Second, the md5sum
of a CD/DVD after you burn it. Both must match the original one, taken from Ubuntu hashes:
If you run Linux currently and want to check this ISO without having CD/DVD ot USB, you can run it as LIVE from you hardrive. It will cover all the compliance, because my the time it has started, Kernel, modules, drivers, apps and most subsytems(audio, video, network) are running, which is the same for your machine after installation.
- Place your ISO file to
/live
:
sudo mkdit /live
sudo cp somelinux.iso /live
- Add new menu entry to the
grub.cfg
sudo gedit /etc/grub.d/40_custom
menuentry 'ISO Ubuntu 14.04 2014 Live' --class os --class gnu-linux --class gnu --class os --group group_main {
set isofile="/live/ubuntu-14.04-desktop-amd64.iso"
insmod ext2
insmod loopback
insmod iso9660
loopback loop (hd0,msdos5)$isofile
linux (loop)/casper/vmlinuz.efi file=(loop)/cdrom/preseed/ubuntu.seed noprompt boot=casper persistent iso-scan/filename=/$isofile quiet splash --
initrd (loop)/casper/initrd.lz
}
TO DO:
change in the menu entry above the code name for your partition, holding /live/somelinux.iso
, in my case it's hd0,msdos5
because it is on /dev/sda5
/
change the file name from somelinux.iso to yours, in my case I have: ubuntu-14.04-desktop-amd64.iso
sudo update-grub
