Hi. My laptop stopped booting after Windows Update tried to upgrade the bios to version 1.32.0.
The regular Dell bios recovery doesn't work (both autorecovery and the "hold ctrl+esc while inserting the power" methods), it just crashes and reboots if I use newer versions of the bios and downgrade to older versions isn't allowed.
If someone can help me correcting the bios I would be very thankful.

Have attached a bios dump with this post.

post moved..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread.

Hi. How to create dump file without disassembling laptop and desoldering BIOS chip? I preffer a free software
And laptop itself works fine. It is non-touch version. I swapped display to touch version but non of my OSes detects the touch capability of new screen. Everything is connected correctly, that is why assumed I need a new BIOS.

I was referred to this thread by rex98. I have a Precision 7540 with the 8FC8 nonsense. His tool wasn't able to work with the dump...

Thanks to all for any help. I am feeling really terrible about being unable to see it all through to the end...
