Hi guys. I have got a packard bell easynote tj65 and i want to reset windows 7 in it. I have got a OEM license so i can't reset windows by CD. But i tried to push alt+f10 at the start and there was an error like this "hdd recovery convalidation failed" . I have tried to scan the hdd with command prompt but there's no file corrupted. What is the problem? Thank you.
