I'm setting up a "lab" computer to work with Windows Server and Linux at various times. Because of space, I'm planning to run it as a headless server and use Remote Desktop, UltraVNC, etc.
Currently the system boots into Windows via GRUB - with Linux as another choice.
I don't thinkeither UltraVNC or Remote Desktop can be running when the GRUB menu appears.
I don't want to use a KVM.
Any ideas? Things like "alternately boot to one or the other" (not very convenient!) or "a runtime command to boot to this or that next"
Under the assumption that Windows Server would be running "normally", is there a script one could run to boot into Linux next just one time? Or, might there be scripts to run in both Windows and Linux to "switch to the other OS at the next boot"?
I can write batch files OK for Windows but I'm not sure about the equivalent for Linux. Seems obvious that whatever .. would have to access one of the GRUB files .. but figuring out which one that might be is a real chore in the Linux docs. I don't want to become a GRUB expert just to implement something simple.
