Dear Jacob,

Is this System Reserved Partition is still required if we are not using bitlocker encryption? I read somewhere Windows 2012 Server are using this for bitlocker encryption.

Thanks a lot for this wonderful tech blog.

It's not required unless you're using bitlocker.

This is beautiful! I found other super complicated crazy instructions that require a PE or recovery disk and a ton of commands.

This worked for me, sweet and simple.

Thank you so much.

Just did this on 2012 R2 DC edition. Did not have to mark C: as active since it already was the OS drive, just not the boot drive.

Thank!

I had a problem upgrading in-place a Domain Controller Win 2008 R2 to Windows 2012 R2.

Install stop with error:

"Setup cannot continue. Your computer will now restart, and your previous version of Windows will be restored."

I had to Remove System Reserved Partition following the instructions and then run the install.

Now I have my DC as Windows 2012 R2!. Thanks!

Hope that helps!
