When i turn the laptop, it does not load i get "system recovery option" its my brother laptop all was going ok he said last night , startup repair is detecting errors but unable to fix them ! No system restor point, windows memory diagnostic tool did not find any errors, i still have 2 options command prompt and windows complete pc restore, about this option i don't have the laptop recovery option but his laptop is similar to mine i got "acer aspire 6920G" him "acer aspire 8920G" everything is the same just the size, please if someone can tell if it is possible to use my recovery cd with it, or if there is anything to do with cmd, or any other suggestions.
