So i have a pc i use as a server, i run without a monitor and keyboard connected. It has an older gpu installed just in case. I currently run 2, but want to expand to 3 operating systems across 2 drives(windows 10, debian 11, some os for docker). I don’t want to run them on a VMM or hypervisor, since i had some issues with klipper. Is there a way for me to switch which one i’ll boot into when turning on my pc, without having to for example selecting the os in grub using a keyboard? Can i do that process remotely?

    From your Linux systems you could run grub-set-default or grub-reboot. I don’t know if there’s a version for Windows.

    Not really. You could buy a kvm so you could remotely connect to that device and then select the OS you want in grub. But that is essentially connecting a monitor and keyboard.

    If you are using Grub for booting, your could do a script for editing the default OS and use that for rebooting.

    Or alternatively use networking capabilities of Grub as shown in this exemple.
