I currently have a mini PC with a dead CMOS battery. Its got a built in/emmc install of windows 10, and a Proxmox install on a separate SSD. It'll boot into windows by default (even when I want it going into proxmox), and its kind of annoying to reboot, remember/hit the boot select or UEFI screen fast enough and pick an OS.

I can't remove the windows drive. Its soldered in.

On another system that runs linux, there's a command line way to boot into the UEFI

Is there an equivilent powershell or cmd builtin or other way to boot into UEFI from windows without going through the shift/restart dance?

  • @Gantendo I think Journeyman Geek is testing us ;-) ?. I think this is the best way. Great comment (answer!), though you should have entered it as an answer.

    With the small addition that it needs to be run as admin, it works. As for 'testing' - its not really documented here, and we are trying to build a knowledgebase. This is both 'low hanging fruit' and surprisngly hard to find. @Gantendo you might want to post this as an answer ;)

  • Can you replace Windows on the soldered drive with Linux and configure GRUB so that it boots the other drive?

    I don't really want to - I'd like the option of getting it as stock as possible should someone else need it, and I should change the battery soonish which would solve the underlying issue
