Hi guys! I got too tempted to test Windows 10 on my SP3 so I did install it. But some of the VPN software that I need wasnt supported so it failed. Twice. In the saving process I had to disable Bitlocker when trying to fix the OS, but it was FUBAR. (Long story short, PC stopped booting when VPN software was installed..nasty) So - I reinstalled from the boot. Real clean factory reset and everything is working fine again now with 8.1. But Bitlocker is disabled and it would be nice to have it running again. When I try to enable it for the C-drive I get the following message "This PC doen't support entering a BitLocker recovery password during startup. Ask your administrator to configure Windows Recovery Environment so that you can use BitLocker." Well the administrator in this case is me and I checked that TPM is still enabled in Bios so I would belive everything is ready. And it was working fine before my Windows 10 experience. I have tried to disable and reenable TPM from Bios, but no difference. Why is this so hard? I also tried the Administrator approach (google) and even search this forum without any luck. Any ideas?
