Tested on Lenovo x220 and x450. Secure boot turned off. Selected USB from host bios drive selection. Bounces to the next drive on both systems. Installed to disk via DD, and via Rufus in windows. Checked sha1sum too.
Can somebody recommend primary checks I should do to diagnose what is going on here? Kubuntu 20.10 in uefi mode works fine (that was not a dig, just an fyi that I can use the same usb for another kde installer).
Great question, given I haven’t been able to even initialize from “post”, I neither get stdout/stderr or journalctl output. So hence I’m starting very generally. Giving details of the BIOS number (which incidentally is the “latest”) would seem irrelevant at this point.
Additionally other than providing the entire file output of a clean image install onto USB, it might be easiler to assume there is no change to the standard:
Well the solution for me was to install Ventoy - A boot wrapper for ISO’s. Means I can install any number of ISO’s and it’s SATA-USB protocol seems to be happily registered. In the process I discovered Ventoy awesomeness and I’ll use it for any Distro hoping I do from now on - it’s easier than using VM’s!
