First of all i know there's a lot of topics here that has the same problem as mine but unfortunately i didn't see any answers to my problem. I have a windows 7 ultimate installed on my laptop, it was working fine and i shut down the system normally. but when i tried to open it again the "startup repair" came up. so i tried to click on repair since i thought it was just an error on restarting my laptop. but then i started wondering when my laptop keeps on showing me the "startup repair" and it always stucked-up in that screen. i tried to look for an answer in different sites and no solutions.. btw, the error i get from startup repair when i looked into the log is: "boot critical file c:\windows\system32\drivers\ygfrz.sys is corrupt" <-- i don't know how did that file got corrupted, i didn't install, download or scan anything before the issue occurred. i followed some of the steps that i can find on other sites like: 1. Try using a Windows Repair Disc (burn it on the cd/bootable) 2. try to repair it with the original Windows 7 Ultimate installer 3. tried the /FixMbr, /FixBoot, etc. Here's my main problem: i can reformat my laptop, i can fix the problem by just installing a fresh windows 7 ultimate, but the issue is not whether i can reformat it or install a new one but to GET MY FILES from the hard disk without having to reformat it.. so that's the MAIN issue why i made this tread. any help, suggestions and comments are much appreciated. I just want to get my files.. thanks btw, one last thing i also tried accessing my files by command prompt and it seems that it doesn't show the contents of my hard disk.
