Hi Guix,
I've been having this problem since the very beginning but, as it is not
a "must have" and it only affects 1 of my 3 computers running Guix System,
I've lived without the Grub menu for years.
When my computer boots, I only see a black screen with "Seabios […] Grub
loading […] Welcome to Grub!", but I never get the Grub menu where I can select
a previous generation. After a few seconds, it boots and I get to the
graphical session manager where I can login.
My configuration is the following:
```
(bootloader (bootloader-configuration
(bootloader grub-bootloader)
(targets (list "/dev/sda"))
(keyboard-layout keyboard-layout)))
```
My guess is that it's related to the screen resolution. So I had a look
into `gnu/bootloader/grub.scm` and saw the following:
```
(define-record-type* <grub-theme>
;; Default theme contributed by Felipe López.
grub-theme make-grub-theme
grub-theme?
(image grub-theme-image
(default (file-append %artwork-repository
"/grub/GuixSD-fully-black-4-3.svg")))
(resolution grub-theme-resolution
(default '(1024 . 768)))
(color-normal grub-theme-color-normal
(default '((fg . light-gray) (bg . black))))
(color-highlight grub-theme-color-highlight
(default '((fg . yellow) (bg . black))))
(gfxmode grub-theme-gfxmode
(default '("auto")))) ;list of string
```
Before I try to define a custom `grub-theme` record, to change the `resolution`
or the `gfxmode`, I wanted to ask you guys, for if I mess up my Grub,
I might be in big trouble! ^_^'
Any help welcome!
Regards,
