Partition

I had preloaded xp home recieved spyware and adware virus tried to recovery console said system32 has been corrupt or missing file reinstalled with xp professional from friend now microsoft asking for key within 30 days. Everytime at start up i have an option of home editon or professional. when click home message comes up saying try repair in windows setup by clicking letter R in the first screen now ive tried this nothing happens need help please im on D drive now cant get on C as original

 

Go into professional.
Click start,RIGHT CLICK My Computer,
Click Manage
Click disk management, RIGHT click on C: partition
Click properties, error checking- check now button, if it has a box to click for repair, click it to tick it.

You really need an XP Home disk same as your preinstalled to do the repair, but see how it goes.

All may not be lost, if you had a preinstalled version, and you let us know--
The brand name of the computer
The service tag (if there is one, on the rear of the computer)
As much information as you can - sometimes its held in a hidden partition on your hard drive, and may be retrievable, with the correct information, or, from the manufacturer.

 

I tried that and covert to dynamic now i cant format cant even scan to repair c drive disk. I get a message when booting from home editon \windows\system32\config\system.sav corrupt or file missing im trting to get to par1 for xp home edtion on c drive and im at par 3 xp pro i cant seem to find my preloaded par 1 home how do i fix this file i dont have the org cd rom disk to repair this as its asking to put disk in and click r for first screen windows setup

 

It's quite possible that you can install Windows OK using your friend's CD and your own Windows key from the label on your pc.

This will work if the version is the same (home /pro etc) and the OEM sufficiently similar.
