So I messed around with my boot partition in Partition Wizard and it became unbootable. Had to run repair from DVD which completed successfully, but it seems to have changed the system drive letter from H to G. Now when I boot up Win7 first it's stuck at "preparing your desktop" for a couple mins, then it shows me the empty blue desktop with "windows not genuine" message in the corner and I can't run any programs; not sure if that's because it's not genuine or because the drive letter changed. But I can access cmd through task manager, so I try to run Trilogy 4.2.cmd which is what I've been using lately to use Windows because the other options didn't seem to work. Now Trilogy tells me it's not installed and there are no rearms, and when I select install it briefly flashes an error then restarts windows right away and it starts from the beginning. Bit at a loss now what to do. I tried changing the drive letter back in system repair with diskpart but it goes back to G after a restart. Tried running repair again but it says no problems detected. So I'm guessing it comes down to making it genuine again somehow. Any help appreciated!
