Re: grub not properly installing in GuixSD

I’ve successfully installed guixSD!  Awesome!

Yeah, when I booted the usb stick, I DID see the guixSD grub menu.  I had been blindly pushing “c” for going to the command prompt, instead of pushing “e” to edit the boot command.  I pressed “e”  added “nomodeset” and boom.  I’m now properly booting guixSD and Arch Linux!

Thanks for all the help!


I did add “nomodeset” to the linux kernel arguments in my config file.  I’ll try booting GuixSD w/o the “nomodeset” argument, and see if I can boot.   Because I’m not using mode setting right now, and my OS looks like something out of the 90s.  Something about the graphics just looks looks old.  It’s like the graphics is not clearly defined or something.  There may not be a free and good graphics driver for my radeon APU.  I’ll explore that in a few days.

Yup.  That's correct.  I am asking about how to modify

set root=(hd0,msdos1)    (I think this is the vfat system)

chainloader (${root})/efi/boot/name-of-efi-file.efi


to something like

set root=(hd0,msdos1)    (I think this is the vfat system)

chainloader (${root})/efi/boot/name-of-efi-file.efi

linux (hd0,msdos1)/path/to/vm-linuz-libre    ?


But thanks for reminding me about disabling modesetting.  If I can't boot the usbstick via modesetting, then I probably need to change my config to disable it as well.  Otherwise I'll successfully install guixSD and grub, but the boot process will fail when it tries to load the raedon driver.

I wonder why you don't see the GRUB menu when booting the USB
normally. Do you get a five second blank screen before the kernel

Worst case scenario, you can install Guix (not necessarily GuixSD) on
some other system and generate a new USB image that adds 'nomodeset':

$ wget
...make some changes...
$ guix system disk-image install.scm

...then dd the resulting store item onto a USB drive as usual.

Hope this helps!
