Bug#1108123: Info received (Trixie installation on virtual machine (not tested on physical) don't boot. It remain stucked in GRUB)

[Alex. I. TRIPCEA]

If I choose firmware UEFI x86_64: /usr/share/OVMF/OVMF_CODE_4M.secboot.fd
at installation, then after installation, the system boot without problems.
if, instead, I leave the default value - UEFI - then after instalation the
system remains at grub prompt.
No other differences between the two installations using
debian-trixie-DI-rc1-amd64-netinst.iso.
