A little background: I was trying to launch Battlenet.exe to play some Overwatch. I watched it load in the task manager, and all of the sudden, it would just stop as it took up a little less than 7 MB of RAM. Generally, the launcher takes several hundred. Looking at the desktop, a window would pop up saying "Battle.net is loading, please wait" or something like that, and it would just get stuck. I tried killing the process tree, bit it wouldn't die. I restarted my computer to see if it was just acting wierd, and it would just persist like this. So I tried opening Steam next, same issue even after restarting. So I thought "maybe I just need to run an update". Well, windows update froze like that too, so I performed a restart. It said "preparing to install update". Stupid me, I thought that it was just expanding the compressed files or something. Nope, it was manipulating the computer files.
So, here's my current situation: even though I have "removable device" at a higher boot priority, it will still go straight to the hdd regardless of its boot priority. Really wierd. Regardless, I removed the sata cables fromy hard drive and booted to the USB which I have my copy of Windows 7 64-bit on. I try startup repair. Nope. Failure code 0x15. Tried rebuilding the BCD through command prompt. No dice, it recognizes the OS on the USB and HDD and gets confused. I tried one other command prompt command that involved the /recovery flag, and that didn't work either. Something about writing a new boot partition. Whatever. It didn't work.
So, suffice it to say, I'm all out of ideas and getting worried.
Thank you all for taking your time to read this.
