Hi! I have a debian installation on a Ssd disk. I have a second 1tb hard disk. I have an Msi b250 gaming pro mother. Now I installed an 256 GB nvme m.2. It works.
So I installed Guix there from the graphical install. Guided without encryption. And selected GPT partition during installation. It all worked, it installed on the disk. But when I reboot, and select that disk for booting, it returns a text message that says that the disk is not bootable. So it stays struck there. What does I have to check? Did I make something wrong, missed any step? Maybe a grub issue? Thanks! Tomas Chapunov
