I have a WinPE flash drive from which I'm trying to use diskpart to mark a partition on a system as active.
I am able to mark either a partition or a volume as active while in the diskpart tool, and as long as I keep the tool open I can list and select and do other things all to my heart's content and it will continue show the desired item as active.
However, as soon as I exit diskpart it loses the setting. If I immediately run diskpart again it no longer shows any active partition or volume, and the system will not boot. I even tried pulling the plug while diskpart was still running, in case it was part of diskpart's closing process that was causing the problem. There are no other drives in the system, and I've also tried removing the WinPE drive.
There are no errors. Again, as long as I don't exit the diskpart tool it will show the partition as active, but the setting is gone as soon as diskpart closes.
How can I fix this? I need to be able to set the boot volume in a batch script from the WinPE environment.
