This is probably a duplicate of 1842320.
On upgrading to 19.10 a boot fails with grub immediately reporting an
"Out of Memory" error after prompting that it is loading the RAM disk.
By default the system is unresponsive at this stage, hitting a key does
nothing.
I tried the workaround described in 1842320 for this, explicitly setting
GFXMODE in Grub to 640x480. This resulted in the system successfully
responding to the "Hit any key" prompt, but still failing to boot. The
boot failure is a blank screen, no icon, and no progress.
I can still boot the system with my pre-existing 4.4.0 kernel but both
of:
Found linux image: /boot/vmlinuz-5.3.0-24-generic
Found linux image: /boot/vmlinuz-5.0.0-37-generic
fail to boot.
