Anthony Mel Posted December 14, 2014 Report post Posted December 14, 2014 Currently I have a Windows 7 machine that has Bitlocker. I just want to know the best way to wipe the drive (format) and install Windows 8.1 via a task sequence. Right now I have Disable Bitlocker -> Restart in Windows PE -> Partition Disk 0 - UEFI -> Pre-provision BitLocker -> Apply OS, etc.. Also, will the pre-provision Bitlocker setup reinitialize TPM? Would that work? Quote Share this post Link to post Share on other sites More sharing options...
