I have the same issue on Lenovo T540p and the latest BIOS update. It has no dual graphics, only Intel. Instead of the GRUB boot menu I only see a black screen with big "Lenovo" logotype. After a while, Ubuntu is started automatically, as it is the first entry in the boot menu. However, the boot menu is functional with the up/down keys + Enter.
Starting the PC from an external drive with Ubuntu life media or MultiSystem USB drive, it's GRUB boot menu is visible as usual. -- 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
