Using a brand new Surface Pro (first generation) out of the box, installed current updates, then 8.1, and any further recommended updates after 8.1 was installed.

I've installed a two other things that don't seem connected to the issue: the Cisco Anywhere VPN client and Visual Studio 2013.

I'd like to enable Bitlocker, but during the verification step, the following error is displayed, with no options to continue:

This PC deosn't support entering a BitLocker recovery password during startup. Ask your administrator to configure Windows Recovery Environment so that you can use BitLocker.

The "administrator" in this case is me, and I don't:

  1. ... understand why this has happened
  2. ... know how to fix the issue, as if it's really necessary to make this change, what would I do?

I had the same issue... as you stated, the 8.1 upgrade wipes out the Win RE environment from the recovery partition... No clue why this is happening, but it did.. If you look in the disk manager sure enough the partition is now 100% free when under win 8 there was content.

You can also confirm this by running reagentc /info

The fix is simply recreate the winre area in the recovery partition by copying the winre.wim file from the c:\windows\system32\Recovery folder... The steps I followed to accomplish this was:

set recovery partition letter in diskpart (I picked Q) Robocopy.exe C:\Windows\System32\Recovery\ Q:\Recovery\WindowsRE\ Winre.wim /copyall /dcopy:t reagentc /setreimage /path Q:\Recovery\WindowsRE reagentc /enable go back in disk part and remove the drive letter set before

Confirm it works with: reagentc /info

I haven't had a chance to try this on my Surface -- I'll check it out. It sounds promising. –  WiredPrairie Nov 21 '13 at 19:50
Sorry, it didn't work for my Surface. There was an error in the enable step about the file system being the wrong format (even though I verified it was NTFS). I ended up building a recovery disk/stick, and reinstalling from scratch. –  WiredPrairie Nov 28 '13 at 12:06
