There are a few ways to recover from this, but probably the best way is to get a new hard drive, install the OS on it and then add the bad drive back to the system as a second drive. That way you can attempt to recover anything you might need before reformating or doing any other type of recovery.
Then go to Microsoft's knowledge base and look up the error your getting, and use the recovery procedure that looks best given your circumstances and situation. READ all the info about the procedures first - some will not preserve data or will make possibly unwanted changes to your system.
I dont understand why they have a recovery partition on the hard drive and you dont have access to it to reinstall windows only and keep your other information. Even with the disks it wont let me re-install windows.
If I had a new copy of windows could I re-install and not loose everything else?
I had a corrupt registry file a while back and had to jump through hoops to get it restored, but it was possible. I was not able to get anywhere using the recovery console, so I went looking. The KB article I used successfully was this one:
HOWEVER, my install was not an OEM install, and that KB article specifically says it may not work with OEM installations.
Most OEM installs require you to create a restore CD or use a special recovery CD they supply to restore the system, but this is usually just a completely new install and overwrites everything to put th origina factory install on the disk. I.e. you'll lose your data.
I think the safest bet is to get another hard drive...
I got another drive and loaded everything from the restore disk on that. I hooked up the old drive as a slave to try and salvage what I could and the new drive got corrupted so I wiped them both out. Had to have been a virus.
Now I cant get windows to work correctly.
Its a mess............... but the machine is only 3.5 years old so I will keep at it until I get it right.
Probably the HP buttons driver, is it under "Human Interfaces Devices"? I checked out the 725n, I don't see any drivers listed for that machine on the HP site, but it looks like it has an nforce2 chipset, so I would download the nforce2 drivers from nvidia.com.
