Hello,
I have a dell XPS 13 9350. A client came to us with a prompt for Bitlocker recovery key (not challenge/response). Once recovery was complete, the device attempts to boot and responds with "no boot device found". The recovery type for this computer is technically Bitlocker Challenge/Response but it seemed to have broken so we have to export the actual .bek file. Once we did this it was able to bypass recovery but then no boot device was found.
What I've done:
- Originally there was only 1 boot uefi entry - "Sophos Boot"
- I reset the bios to defaults (made sure to set UEFI again afterward)
- This made 2 additional boot options for the computer to boot from in UEFI boot settings (the actual hard drive and "Windows Boot Manager")
- This makes for a total of 3 boot entries in UEFI boot config: Sophos Boot, Windows Boot Manager, and the actual UEFI hard drive entry
Afterward - when I attempt to boot from "Sophos Boot" it proceeds to the 5 second countdown to trigger a Bitlocker C/R session then fails to boot because no boot device is available
However, if I set it to "Windows Boot Manager" the laptop does not do a Bitlocker C/R countdown and boots straight into the OS.
This leads me to think that the "Sophos Boot" UEFI entry is broken. Is there a way to repair this? As the hard drive and data are still in tact. Thanks
