I have an application where I need to boot to Linux, execute automated scripts and then automatically boot to Windows.

Another use case would be to boot a Linux kernel to update the processor microcode, and then kexec to GRUB/syslinux to boot Windows -- because the microcode won't survive a full reboot.

I've heard of grub4dos (link (unavailable), archived version), but it seems to be discontinued, so is there a way to do it with GRUB2?

I would basically need a loadable image of GRUB for kexec. I tried to load the images found in this explanation, but they don't seem to work. Thanks for any hints.

UPDATE

Found this post from back in 2014, which says that this was not yet implemented in kexec.

UPDATE

It seems that that just is not yet implemented in kexec. See bugs.launchpad.net.

I have an application where I need to boot to Linux with grub, execute automated scripts and then automatically boot to Windows.

Another scenario in which I would want to do something like that, is to boot a Linux kernel to update the processor microcode, and then kexec to grub/syslinux to boot Windows -- because the microcode won't survive a full reboot.
