Created a recovery drive on build 9879. Went to create one for build 9926, option check box is grayed out and it states that key files are missing. The folder is there with the image so I'm not sure about missing files.

I had several BSODs after the initial install but that problem was corrected but I'm not sure if that's the reason for this or not. I have no intention to restore from this medium but only would use the USB drive to get to WinRE options but wonder what the issue is.
