Hello Everyone, MSI laptop - Windows 7 32 bit very recent fresh install (1 month). 320 GB Hard drive partitioned in two= C" & D" for data. The other night, I started my laptop and the first thing that appeared after boot-up was the windows utility. The message said: " Drive C has to be checked for contingency". Then it started checking the partition..... found corrupt index tables & files and deleted them and proceeded to remove every permission from the administrator group in that partition. This process lasted for about 55 minutes and the computer shut down. I re-started the computer and to my surprise, no password window, no desktop picture (black) but the program icons are there. Suspecting it could be a Windows issue, I shut the PC down and proceeded to repair Windows using the OS DVD. After following the prompts, I decided to restore to an earlier date; picked the latest date & went through the entire process only to get an error at the end of it basically saying it could not be done. Tried 2 more available dates but still the same error code before the end. Now I cannot access drive C: at all nor can I run any programs in that partition. Since the OS is installed in it, windows is giving me a message that my OS is not legitimate and the licence can't be validated probably because it can't access that data. Fortunately, mostly all my personal data is on partition D: and is still there. If anyone has an idea on how to fix this issue, please let me know as soon as possible. Thanks !
