Hi Folks

Today I updated the BIOS in my Precision 3510 to version 1.34.3

I've done this numerous times but it has always been just fine.

The reason I did it was because Dell Command update recommended it.

It was working like a dream I did that but now it will not boot.

I get messages saying that there is no bootable media present.

I've tried legacy and UEFI boots to no avail.

If I go into the BIOS setup and press Add boot option it says that there is no file system present.

I can boot from a windows install USB and in the command prompt I can go to the C drive which shows 1 file of 0 bytes and the entire drive as free. Can I assume that it is bricked? Can I do a rollback of the BIOS via USB? Should I just reinstall windows?

This has never happened before so I'm a bit stuck.

Any help Much appreciated.

Chris
