Hello!

(I'm not sure where should I go with this, but seems like it's about
"Debian boot" and likely has something to do with the installer.)

On a new Bookworm installation I see a new issue: before grub-efi shows
the menu, it pauses for a whole few seconds on "Welcome to GRUB!", and
then flashes an error for a split second:

error: no such device: /.disk/info
error: no such device: /.disk/mini-info

Trying to find any information about this, the only thing I've found is:

https://unix.stackexchange.com/questions/753732/what-does-grub-error-no-such-device-disk-info-mean-and-how-to-fix-it

So this is likely not for the upstream grub, but for the Debian
adaptation of grub.


I've tried to fix it for a while, and now I'm not sure if the error is
still there, because it flashes so quickly. But a significant
multiple-second delay on "Welcome to GRUB!" on a very modern PC is
definitely there. Is there a way to see the logs from this stage of grub loading?


(Please CC me - I'm not on the list)

These (harmless) messages are caused by the early grub.cfg embedded in
the monolithic EFI GRUB image memdisk, which was originally designed for installation media. It has been removed since version 2.06-14 when the
FAT memdisk image was replaced with a SquashFS one.

Thanks for the info! So it won't be in Bookworm then, but should be
there right after.

Harmless messages are fine, but what could be taking about 4 seconds of
waiting at "Welcome to GRUB!" before the menu? Is there any way to find out?

You can try adding 'set debug=all' and 'echo <step>' commands in /boot/efi/EFI/debian/grub.cfg and /boot/grub/grub.cfg.
