This looks like something is not doing what it needs to do... If you do a BMR or volume recovery from the recovery media, it should overwrite everything. Finishing in 3 seconds is indeed not normal
. In our utilities on the recovery media, there is a possibility to export the logs to a location (your NAS for example). It would be very handy if you upload them on some onedrive, google cloud, dropbox or something and DM the link to d.popov so they can investigate.
I am not sure about your boot process. I assume that your pc was installed with UEFI enabled, and because your recovery cd is built on that pc, it will require it... But again, not sure about that
