BIOS auto recovery update blocked.
I have a Dell XPS 9500. Up until now, a great laptop. But when I now boot up, it beeps twice and then attempts to update the BIOS, but can't - "BIOS update blocked due to unsupported downgrade." It then repeats the entire thing, over and over, but is stuck in a loop. It just won't boot.. I don't have another laptop to create a USB backup thingy, and it won't get past the screen.
Any ideas?

Can you not interrupt the process and possibly turn something off so you could download the repair Bios?
Do you have another computer you could download the repair Bios?
If you have another device you could access the Dell site, you might check the link below.
