Hi,
My surface pro 3 started asking me for a bitlocker password despite me not changing/adding anything. Not sure if an update was the culprit. Anyway I managed to retrieve the bitlocker password but all the tablet kept asking was for the country and keyboard when booting up. trying to repair or reset did nothing. After looking on the internet I downloaded a recovery image to USB and followed the instruction to reset. All seemed well with tablet saying it was "Recovering this PC" and started at 1% and counting. The tablet got to 2% and just sat there for ages. I decided after about an hour to restart the PC and a window came up asking to clear the Trusted Platform Module (TPM). I ended up clearing this and rebooting and the tablet again stated "Recovering this PC", but again just sits there at 2% for ages. Tried switching off (hard reset) and trying another reboot. Same sequence as before, get American Megatrends logo up asking about the TPM, choose language, choose keyboard, Troubleshoot, Recover from a Drive. I am not worried about any data as it was backed up just want a W10 tablet up and running. Appreciate any advice on way forward.
