Question [Help!] Accidentally converted Boot Drive to Dynamic!

[Ajwork]

I just now made a huge mistake and converted my main boot drive to Dynamic in Windows 10 Disk Management. I haven't restarted my PC yet, but I know that when I do Windows won't boot without being reinstalled. Is there anyway to undo what I've just done without having to do a clean install?

You should be able to change one byte in the partition table, if the drive has an MBR partition. GPT partitioning may be a little harder. Which do you have?
