hi there,
first time here so here goes, not able to boot into my Linux at all, have re-installed grub but to no avail, I have tried boot repair and can see the report, it failed to repair the boot, I have a black screen that flashes 7 times then just stays black, how do I upload the report to get help from the community, many thanks and kind regards to you all...

If you have already created a boot-repair report, then paste the URL link in this thread.

Here is some more info https://help.ubuntu.com/community/Boot-Info

You should run boot repair with the Create BootInfo Summary option then post the link you get when it finishes. When you open a thread, you should always post what you are using and the version such as Ubuntu 20.04, Kubuntu `18.04. Also indicate if it is the only OS or if you have a dual or multiboot system, which other OS's do you have. All this info should be in the boot repair output so the suggestion to post that link is the best option.

You've got Zorin OS 15.3, which is not Ubuntu, but still based on Ubuntu 20.04. The kernel is a little behind, at 5.4.0-77, whilst Ubuntu 20.04 is at 5.4.0-80.

As the screen flashes several times, then stays black, my guess is that the system boots, but has some graphics driver problem, causing a black screen. I don't know how Zorin OS handles graphics drivers. Maybe somebody around here knows. In any case, telling us a bit more about your graphics hardware may help.

Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.efi file!

Does this not work?

Did the system ever work?

some mentioned this could be graphics related as the screen is black, AMD Raven graphics, the report tells me to make BIOS boot on sda1/EFI/ubuntu/shimx64.efi file, I can access options with esc and BIOS settings, then I don't know what to do ? many thanks to you all..
