Cant choose Qubes os in boot menu after assembley

Hi everyone
I must change thermal paste in my T430s with qubes os 4.1 on It. After put all parts together i turn on my laptop and i saw boot menu. After Click Enter on qubes os Its flash and appers again. What i should do? Did i broke up hardware?

Have you tried booting from an USB stick?

If so, can you try:

efibootmgr -v
ls /sys/firmware/efi/
ls /dev/sd*
ls /dev/nvme*

and share the output?

maybe that’s sound stupid by the problem is incorrect hard drive connect
