After attempting to upgrade to 22.04 from 20.04 on a Asus VivoBook I'm getting a black screen only showing

dev/sda2: clean, 552599/6111232 files, 7119295/24414464 blocks

and a blinking cursor. I've created a live USB stick from which I was hoping to fix the system but that doesn't boot even though I've checked the BIOS setup that the system would boot up from USB. Attempting to connect wirelessly via CLI and updating the system by command line doesn't work as the NetworkManager fails systemctl status NetworkManager.service.

How can I restore the system?

I managed to Boot to the live USB drive (just by chance) changing the boot order to first UEFI: SanDisk, Partition 2 and then ubuntu (P2: Sandisk SD9...). The boot failed first and then booted the ububtu partition. This is probably not how things are oppose to be but it works.

I had the same problem trying to upgrade from 22.04 to 24.04 with a slight difference : my computer rebooted and I was able to log in. I then decided to install the USB wifi antenna driver (a Realtek device) the day after. When I switched my computer on the day after, neither Ubuntu nor a 22.04 USB live key would load. I attempted to change the BIOS parameters many times but nothing changed. During one of these boot attempts, I accidentally pulled off the wifi USB key and the Ubuntu flash screen appeared. I could then reinstall 22.04 and then decided to stay on that release. Hope this helps!
