Hi, I'm trying to boot GUIX. I've copied GUIX on to my usb, but I have not been able to boot it sucessfully. According to the instructions I need to access the BIOS to do this. I've read that is done by pressing one of the F keys on startup. However, my laptop has been librebooted so I don't think this is possible.
For arch, at least, all I had to do was copy arch to my usb and use the grub prompt to boot from the usb. It seemed to me that it should be the same for GUIX but when I try this I'm just taken back to the initial prompt that asks me what I want to boot from. I'd really appreciate any troubleshooting help. L
