Yeah, not yet.

If I get to that point, yes, I'll reinstall. Right now I still want to make this work.
Okay, now.
I discovered this morning (while trying to install my Acronis trial) that a small issue I had last night when I was making the Macrium PE boot disk (it would error when I tried to install the WAIK to make the bootdisk, but at the time I thought nothing of it and just made the thing on my Win 7 laptop instead) was in fact more widespread: my installer is borked. Mostly I'm getting 2502/2503 errors when I try to install something new.
A little web searching turns up that this is fixable, but since I'm pretty sure this is a result of Automatic Repair undeleting the partitions in order to restore Windows, who knows what else might be screwed up.
So the distinguished gamer from Houston is correct, it's time to suck it up and start over.

It shouldn't be horrendously awful because all of my Modern UI stuff should restore once I get it hooked back up to my MS account, and since the machine *will* boot and work, I can make a list of what I had installed tonight, back up my user folder from the D: drive here, and just copy it in when the new install is up. That way iTunes at the minimum should pop right back up where it was when I reinstall it, which was something I had to tap-dance around to avoid losing data when I moved it over from the old PC. And if I have a list of What Was Important, I can just plow through it and check stuff off.
