I bought a DELL e6220 second-hand. The computer does not have any damages, and it worked correctly at the moment of purchase. However, I tried to update Windows 10, and my BIOS crashed.

 

Now, I have the following problem. 

 

1. When I start the computer, I can see that BIOS is loading; however, it hangs all the time ( please see the attachment )
2. When I press F2, the Bios tells me that it is "preparing entering setup," but it hangs again and does not enter setup.
3.  The same situation is with F12. It informs me that it prepares a one-time boot system, but it never achieves it.

 

I have already done the following things

 

1. I checked my RAM - they work correctly,
2. I disconnected the hard drive - but the situation with a hard drive or without it is the same.
3. I disconnected for a night CMOS and connected again.
4. I did most steps that I could find on online communities.

 

I have a question what shall I do now? The computer does not have any OS installed. The disk has been formatted.

 

1. Is there any chance to get any recovery tool?
2. Where can I get it? Is it for free, or is it paid tool?
3. How can I use it if my BIOS hangs constantly?

 

Thank you in advance for your help and assistance.
