I have a Google VM instance with ubuntu-minimal-2410-oracular-amd64-v20241115 image and can't seem to get the GRUB menu to display. I want to boot an ISO from the instance to test. I have tried the Shift (right and left) and Esc keys during boot but can't get the menu to display. I use the SSH in browser option(using Firefox).
I didn't see a version of GRUB. Using BIOS. Installed GRUB to /dev/sda. No errors. Ran update with no errors.
Here are the partitions of the machine.
