Sandi, I hope this is the correct procedure reporting via you. Thanks for the email. My HP system seems a little different than yours, I finished up with the two latest kernels and a warning that I also had an old kernel that was not of the secure boot (efi) variety.
I deleted the old kernel, to find later that it was the old kernel that worked best occasional. I cannot directly install Ubuntu 20.18 from a USB stick, it wont even load up. I managed to install Ubuntu 17.10 then upgrade to Ubuntu 20.18 The first non efi kernel was 4.13.0-21-generic. I upgraded from Ubuntu 17.10, and am informed that a non efi kernel 4.13.0-46-generic has appeared and prevents completion, I have deleted this kernel. After aprox 20 boots I gave up trying to get into the computer. (there is no logic in getting the computer to boot up, the more I try the less chance of success). Next day Five attempts booting with kernel 4.15.0-3-generic failed, third attempt with kernel 4.13.0-21-generic success A crash happened on the HP pc this morning and I was asked if I could supply any data, hence this email. I hope this information reaches all concerned and is of use. Regards Jim On Wed, 12 Sep 2018 at 00:00, Sandi Vujaković <[email protected]> wrote: > > Jim, I only know the GUI way of doing it.
