[SOLVED] Live ISO repeatedly reboots

Ask Fedora
1

I’ve attempted to boot the live ISO on two different machines and it repeatedly boots into the ISO’s boot screen:

Both machines have secure boot off and fast boot off. Is there some kernel parameter I can add that will give some diagnostic information that could help me figure out what’s going on?

You could try booting with both rhgb and quiet removed from the kernel parameters.

Might let you catch whatever the last messages were before the machine is automatically rebooted.

Unfortunately, when I press TAB, I don’t see either of those boot parameters. The screen does show it attempting to load vmlinuz and initrd:

If this is booting using grub, you should be able to hit e to edit the boot command list. I’m not a coreOS user though so no idea if it uses grub or not.

How different are the machines? It could be useful to post the models and basic specs. Look for the models at http://linux-hardware.org to see if others have installed linux and check the UEFI/BIOS versions against what you are using.

Huh, very weird. Apparently the (very, very old) thumbdrive I was using was just a tad too small although I don’t recall seeing any errors while I was burning it. It now works fine with a larger drive.

Some cheap/fake drives overwrite data when they get full, so users think they wrote the advertised capacity and don’t complain.
