I'm trying to install Ubuntu 24.04.1 on a late 2009 27” iMac. The installation appeared to work flawlessly, but when I tried to boot the system, this is what happened.
- POST completes and does the Mac chime.
- Screen displays a non blinking cursor for 7 seconds.
- An Ubuntu loading screen displays for about 3 seconds, then the screen goes black and stays that way indefinitely.
I tried to bring up the Grub menu, but can’t seem to do that. My thought is that I’d change the boot option to add no mode set which I had to do when booting from the installation USB.
I ran the Boot Info and here's the output: http://paste.ubuntu.com/p/9txMb7dd8P/

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda2,
using the following options: sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 24.04.1 LTS entry (sda1/efi/**/grub.efi (** will be updated in the final message) file) !
