This old Acer 5720 ICL50 already runs Ubuntu 20.04 Bionic Beaver and Linux Mint 20.3Una on 2 separate partitions. Both work fine and I update monthly. The machine is only used a reference machine, not for everyday use.
I decided to install Ubuntu 22.04 LTS Jammy Jellyfish on it. I downloaded the ISO using a Lenovo T410 I use everyday and burnt it to 16GB USB stick. I booted successfully from the stick on the Lenovo and "tried" the new version - all fine.
Inserting stick in Acer and trying to boot achieves very little. It boots, and displays "GRUB" top left of screen, a few moments later the grub menu but thereafter just a flashing underscore top left of screen and nothing thereafter.
Is my old Acer just too old? Or is there something I could press during boot? Maybe, get into the stick and change something? Is there anything else I need to supply to try and answer these questions?
I tried using GNOME disks to write the ISO to the stick with the same problem. In the end I reluctantly booted another Lenovo T410 running Windows,downloaded the ISO and used Rufus to burn onto the stick. And this worked! A quick GRUB followed by WELCOME and the usual menu where I could run up the live USB, and try the Jellyfish. I will think about installing another day.
So,to conclude I have managed to partly answer my own question - no idea whether I will actually manage to install fully. I am guessing Rufus managed to do MBR with EFI/BIOS whereas Startup Disc and GNOME discs wasn't.
Do I raise a bug?
