how to replace lost system32 files

Did something really stupid. In an attempt to follow Instructions to replace window media player 12 with
WMP 11 for work purposes, I moved system 32 files from windows/system32 folder to
A folder on the desktop, and tried to replace them with "new" system 32 files downloaded from the instruction website. I manually set a restore point prior to doing this thinking that i would be able to restore everything back to normal if a problem developed. Well of course the moving and replacing not only didnt go as represented, but the pc now won't boot. And system restore says there are no restore points to go back to (why??). When rebooting pc goes into a type of repair mode the name if which i cant remember, but says it is unable to correct the problem. I do not have a recovery disc or win 7 disc--got lost in the move. And of course I have tons of data, music,etc files, so I don't want to restore PC to original out of the box condition. I would highly appreciate any help any of may have to offer. Thanks very much in advance.

 

Hello eyeopr8r, are you able to use or borrow another pc to use this tool ??

Nick T, Major Geeks now considers Hiren's Boot CD to be warez. A better alternative would be Ultimate Boot CD.

 

nickt and mdonah, yes I have acces to other pc's. Have tried startup repair over 5 times with "unable to repairt" message. System rewstoe says there are NO restore points even though I manually set one prior to my stupid behavior. Have used command prompt to run sfc scannow, with message "unable to repair". Have just downloaded iso of win7 home preimium x 64, as I've been told I can try to use it as a "repair install" of win 7. Willl await your instructions. Thanks very much for your replies.

 

live cd

can repair damaged FAT/NTFS boot sector
maybe work.

 

Hey guys sorry about the Hiren link, I was unaware of the situation until you pointed it out mdonah, thanks for the info. :-o

 

Did you get this ISO from an official Digital River download link? If not, it's bogus.

As far as using it as a "repair install", NickT or someone else will have to help you with that. I'm still running XP Pro and am awaiting the arrival of my 7 Pro install DVD w/COA.

 

Yes I went to digital river website for it. I will doulble check that the website is the official one. thanks

 

Hi eyeopr8r Download your new version of Win7 and download it from a legal site. Burn the ISO to a DVD, in ImgBurn Boot from the disk and do a Repair Install This should correct this issue.

 

Hi, thanks for reply. I had tried that, and got just past where I had to type a name for the user, and then it went into same blue window, stating that windows files were corrupt and could not be repaired. So I booted with hirens cd, saved data, and did a recovery of oringinal software. I have since come to conclusion tht my win 7 iso file boot disc, must have been corrupt itself, because everything I read says that one should be able to do a complete or repair install by booting with that disc.

 

Are you sure that win 7 iso file boot disc,has been corrupted?
If yes then you may have got the solution for your problem.
