I installed Wubi on my Windows 7 64bit machine yesterday, and since then, the windows partition is ridiculously slow. As in, takes an hour to boot. Once it boots, it takes ten minutes to log in. Rebooting takes an hour or so to shut down.
The C: drive is an SSD, but it didn't have enough space for Wubi, so I put Wubi on the other 500gb regular spinning-disk secondary partition. I don't know if that matters.
I did see this: http://ubuntuforums.org/archive/index.php/t-373876.html
but I'm not sure that's a relevant link.
What can I do to fix this problem? If the best solution is to install Ubuntu in a second partition (and by 'best' I mean "able to work again as quickly as possible with a minimum of debugging time, this has cut my productivity to nothing"), then how can I undo this?
EDIT: I believe I'm experiencing issues similar to what's described here:
I tried to reinstall Windows this evening, and it just failed miserably on the drive. So badly, in fact, that it got to 29% of files copied, and then just crapped out. That means that something on the drive is dead, especially since the same copy of Windows is now installing without any apparent issues on the spinning disk. Looks like the timing of this failure just happened to coincide with the Wubi installation.
