For your information, I have an HP EliteBook 840 G2, I did a fresh install of 21.04 and had the same issue, it uses an "EFI v2.31 by HPQ".
I used following work around which worked. What made the trick was the following changes in the BIOS Setup (after computer start push F10 - go to System Configuration - open Boot Options): Check Customized Boot Check off SecureBoot Boot Mode: choose UEFI Hybrid or UEFI Native (I chose UEFI Native) UEFI Boot Order: put Customized Boot to the top Define Customized Boot Option: choose Add + put the setting: \EFI\ubuntu\grubx64.efi Source: https://askubuntu.com/questions/244261/how-do-i-get-my-hp- laptop-to-boot-into-grub-from-my-new-efi-file -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925010 Title: shim-signed 15.4 does not boot on EFI 1.10 systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1925010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
