I really wish more laptop manufacturers would offer coreboot firmware instead of firmware made by shady proprietary firmware vendors based in China.

Not quite the same issue, but similar in the sense that it was caused by a UEFI that didn’t conform to spec.

I have an HP laptop that I installed Debian on, and it would never actually boot to grub even though I checked the boot entries several times over. You could open the settings and choose the boot entry manually, so it’s not like it was a problem with the OS or with grub. Turned out, this model was hard coded to only allow a boot entry named “Windows Boot Manager” to be loaded by default. I used efibootmgr to rename the debian entry and it booted into grub straight away.

Holy moly that’s absolutely shocking. Yeah I didn’t quite realize how scuffed various UEFI implementations were until I encountered this issue and started looking around. Wild.

Imagine if you remane your install to Windows Boot Manager

Edit: I’m pretty sure you can actually do that with efibootmgr

Guess what? My HP 2000 Notebook PC laptop (not my daliy driver) decides it’s a great idea to prefer “OS boot manager” (WBM), over “Linux Boot Manager” (sysd boot). The funny thing is that renaming the “Microsoft” folder in the ESP to something like “Macrosaft” fucking works. My daily driver lets me just set it in the UEFI BIOS screen.
