Windows 7 Pro is on an SSD, and has the 2 partitions, as normal. Problem is, the main C partition has the gray slashes through it. I right clicked that partition, and I was asked if I wanted to make that "active". Then a warning that may have an issue if I do. Honestly, I've never come across this before.

Duly note, this is a week or so old new system and install. Sometimes I get a BSOD, or on start up it brings up the lower bar saying windows is repairing, or something of that nature.

Question: If I make that partition active with the OS on it, will I be on a path of a full on reinstall of W7 Pro??
