It is possible in many other distros (like the ubuntu example I gave earlier), but once grub has done it's thing, the linux kernel needs to know how to keep going, which means loop mount and squashfs support in the initrd, and probably strange and wondrous kernel boot parameters you need to specify to tell it about the iso file. Certainly the ubuntu example needs funny kernel parameters. So either fedora has the needed support and the info you need to pass to the kernel boot line is too obscure for anyone to figure out, or it doesn't have everything it needs in the initrd, and it won't work at all. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@lists.fedoraproject.org Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Allegedly, on or about 23 August 2016, Tom Horsley sent: > I mean boot the livecd ISO file directly off hard disk. Surely it ought to be possible. GRUB can do a PXE boot, that's just the OS tree from some other source. Perhaps there might be an intervening step that mounts the ISO, but lets you chain into it. Virtual computing boots off an installation in a container. Probably ISO files aren't going to be the best installation download in the future. Optical drives are being eliminated in Macs, PCs will probably lose them soon enough. The demand for blank DVDs has gone down now that movie piracy has changed tack. The future is probably a bootcode and file archive that's not specific to any kind of media. Of course it would help if PC hardware wasn't made to pander to Microsoft's demands, but for their users' needs. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.

ALL Current livecds boot with grub support. Do you perhaps mean boot
from hdd (without grub or from grub to the hdd directly ?
If you wish to burn a boot-able Livecd to the disk directly you can
either dd the ISO OR use livecd-iso-disk (from the livecd-tools package)
like so:
dd option:
hdd=/dev/sdb
sudo dd bs=4M if=~/Downloads/FedoraISO.iso of=/dev/sdb && sync

I don't know if anyone ever tweaked fedora live cds to have
the required support to boot via grub. I know at one time I
read they wouldn't work that way. I do have several livecd
images setup to boot from disk, but none of them are fedora.
Here's one that happens to be laying around:
menuentry "Boot Ubuntu 13.04 live cd" {
insmod part_gpt
insmod ext2
set root='hd1,gpt1'
search --no-floppy --fs-uuid --set=root 83693456-a3ef-4b35-a4bb-e0671367e40e
set isofile="/booty/ubuntu-13.04-desktop-amd64.iso"
loopback loop ($root)$isofile
linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=$isofile
noprompt noeject
initrd (loop)/casper/initrd.lz
}
(I have no idea if it still works, there may be parts missing
after all the time since I last booted it :-).
