In the process of trying to shrink my hard drive partition, I marked my C:
drive (the only drive I have) as “active” in Windows’s “Disk Management” software. When I rebooted, it said something like “boot device not found” (can’t remember the exact wording).
I can’t boot into Windows, but I do have a Linux Mint cd that I’m on right now. From my research, it looks like the equivalent of “Disk Management” is GParted.
So the question is, how can I undo marking the partition as active (within Linux) and be able to boot into Windows again?
Right now GParted looks like this:

It's the same flag. The "active" flag in Windows is called the "boot" flag in Linux.

You can modify the flag in GPartEd by right-clicking the partition and selecting "Manage Flags". To undo the boot flag, uncheck it with the C: partition and add the boot flag on the System Reserved partition.
