Installed Windows 10 Workstation 20H2, 19042.985 1 week ago on a virgin 2TB SSD on a motherboard with hardware TPM module.
Windows installation, only asking me to select the drive(which had no partitions at the time), installed the following:
partition 1: 100 MB "(EFI System Partition)"
partition 2: 1907.13GB "( Boot, Page File, Crash Dump)"
partition 3: 499MB "Recovery Partition"
I then mirrored the system partition on a second SSD. NOTE: Windows would no let me mirror the EFI partition or the Recovery partition, when I right-click them "Help" is the only option. My current system allowed me to mirror all partitions on same setup(2 - 2TB SSDs) and Windows install did not break up the support partitions in this weird way.!
I then tried to turn on Bitlocker on C:, but it fails simply saying "The drive cannot be encrypted."
In my research, I found that Bitlocker has specific partition requirements, like a free, 100MB minimum "Active Partition" with at least 50MB free. I cant mount the EFI or Recovery partitions because when I right-click, only option is "Help", so I have no way of knowing how much is free.
I am willing to reload Win10 to get everything, mirroring(all partitions) and Bitlocker, working, but want to know how to pre-partition so Win10 installer AND Bitlocker will be happy.
What pre-created partition sizes and types will allow Bitlocker and with mirroring(all partitions) of the system drive?
VERY IMPORTANT: Also, need to know exactly what type each partition must be. EFI is staright forward, I assume the system is a PRIMARY, but don't know what the Recovery partition would be, these are diskpart's choices:
EFI - Create an EFI system partition.
EXTENDED - Create an extended partition.
LOGICAL - Create a logical drive.
MSR - Create a Microsoft Reserved partition.
PRIMARY - Create a primary partition.
thanks!
