I also had such a problem. Hardware: old HP ProBook 4330s with Intel graphics and UEFI boot, against HP recommendations. No secure boot.
I could boot by just sitting out the timeout. I found some posts recommending to rename or remove unicode.pf2 from /boot/grub and /boot/grub/fonts. This resulted in an ugly but functional menu. My /etc/default/grub is: GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="resume=none usbcore.autosuspend=-1" GRUB_CMDLINE_LINUX="" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863434 Title: 20.04 grub menu not visible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1863434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
