Valvatos Posted March 30, 2011 ID:407589 Share Posted March 30, 2011 Hello.Long story short; my laptop started giving me the "Operating System Not Found" screen during boot. System Repair, Safemode and System Restore don't work but luckily, my BIOS still detects my HDD and I passed the Memory Diagnostics(?) scan. So I borrowed my friend's Windows DVD (same version) and did a startup repair. After appx. 16 long hours, most of the tests were passed except for this result:"Boot critical file d:\windows\system32\drivers\fltmgr.sys is corrupt"I went ahead and tried to manually replace the fltmgr from the DVD to my system through command prompt, using the method suggested at the bottom of this post:http://forums.malwarebytes.org/index.php?showtopic=77827&view=&hl=&fromsearch=1I followed the instructions and used "d:" for my windows directory and "e:" for my DVD-ROM drive in the command line. (I can't remember the disc drive letter correctly but I assume "e:" is correct since it took several seconds to get a result compared to "c:") and the results were:"Can't open the input file: e:\i386\fltmgr.sy_."Does the DVD even contain fltmgr.sys? Is there a way for me to replace my fltmgr.sys without reformatting, or taking it back to the retail store?Any help is appreciated!PS: I have left my laptop open right now in case I have to go through startup repair again just to access this working command prompt. And I apologize if my post has poor formatting. I am typing through my mobile. I am running Windows 7 Home Premium Edition X64 on a 6mo old Sony VAIO Laptop (VCPF120FD).

sjpritch25 Posted March 30, 2011 ID:407924 Share Posted March 30, 2011 I would probably extract the file from another computer and use a linux disc to replace it. Let me know what you want to do. Link to post Share on other sites More sharing options...
Valvatos Posted March 31, 2011 Author ID:408253 Share Posted March 31, 2011 Hello sjpritch25;Thanks for your reply. I now have access to another computer and have my windows DVD ready.

Valvatos Posted April 1, 2011 Author ID:408891 Share Posted April 1, 2011 Just an update: I managed to backup my files into a pc via Sata to USB and I am reformatting my laptop right now. So far it's stuck at 0% on "Copying Windows files". I hope this works. Link to post Share on other sites More sharing options...
