BIOS does not detect any EFI boot loader, have to boot manually via UEFI shell. What can be wrong/ missing? [Details given.]
When I use the command line tool efibootmgr to modify the UEFI's boot entries, it fails with Could not prepare Boot variable: No space left on device. But I am not sure which device efibootmgr thinks is full; sda1 has plenty of space and is mounted writeable; it seems to be something directly by the BIOS? -- The same message appears when I want to reorder Bootnums, but the reordering still is carried out.

Issue Installing Windows 11 (Reboots into Steam OS During Install)
efibootmgr wiki Use this reference to change boot order if you so choose. Reboot into bios and you should see your windows install as an option to boot.

Installing Arch Linux on VMware vSphere 7.0 using Packer
So I updated the install script to use efibootmgr to change the boot order. It's updated from the looks of things, but the CDROM still boots. Even when I use it to delete boot entries, it continues to kick the Live CD. When I change the EFI boot order manually in the vSphere client or disable entries, it will boot the installed Arch Linux.

Command to reboot into alternate OS?
Assuming you are using EFI you can use https://github.com/rhboot/efibootmgr to change your boot order. This will bypass GRUB. I would create a bash alias to change the next boot device and then restart the computer so you can have everything happen with one command.

I've done it! Uhmm, but there's a teensy little problem
This is kind of late, but just in case anyone else has the same problem, GRUB needs the efibootmgr binary to use that particular target. Here's the github page with source: https://github.com/rhboot/efibootmgr. I imagine it should go in /sbin with the GRUB stuff.

Is it me or is Grub2 outputting "GRUB" on error the worst thing in software design ever?
You can go through the code if you like to investigate.

Why do many tutorials use "update-grub"?
