Dell XPS12 Q23

Laptop is stuck in " preparing automatic repair" and never completes  process . Unable to access recovery partition. Purchased Recovery USB key from Dell and booted to USB recovery key. Got the " Loading Files"  message  and then the Windows logo and the rotating circle   . It stays in that mode for hours with no change., Could someone please help. Had a session with Dell technical support but they had to issue a refund  after they could not solve the issue. Diagnostics came up  good.
