I've reproduced the installation boot menu problem on a Thinkpad X220,
and I can verify that the suggested workaround makes things work. I
have an MR open on the installer to add that workaround:

  https://salsa.debian.org/installer-team/debian-installer/-/merge_requests/69

and that should be in daily builds shortly and the 13.1 point release
next weekend.

What I could *not* do was reproduce this issue on a system after
installation. I checked that more than once, and it worked fine
already. That adds more credence to the suggestion that this is a
timing bug, for me. :-(

I'll be watching for an upstream fix in GRUB rather than updating
everybody's grub config with an update, but for now we'll at least get
installation images working here. That's the higher priority.
