Recently, I wrote a comprehensive review on the newly released Linux Mint Debian Edition (LMDE) version 6 "Faye" built on Debian 12 "Bookworm". If you've not checked that review yet…

In this blog I document my journey in learning the UEFI boot process and discover that not all laptop firmware implement the UEFI standard correctly or how you'd expect.

I'm curious if anyone else has had trouble getting laptops specifically to retain their UEFI BootOrder and if anyone else here has seen behavior like this on devices recently.

    Turned out, this model was hard coded to only allow a boot entry named “Windows Boot Manager” to be loaded by default.

    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.
