Ok yall, here we go. I have a Sony VAIO model PCV-RZ20 desktop. I have had the computer for only about 2 years now but I have downloaded and done so much crap to it I decided it was about time to do a full system recovery back to the original specs from the store. I apparently lost the recovery CD's so I a friend of mine had XP Professional. I went ahead and installed that figuring that it would clear out everything and start it new. Instead, I now had two operating systems: home and professional. This obvioussly did not solve my problem so I went ahead and ordered the recovery cd's for my model from sony. When doing the system recovery an error pops up saying "Disk access:Sense operation failed". Then is says "The recovery process is incomplete. Your system may not operate properly." Then when the computer starts up it says "Error loading operating system" So what do I do? The Desktop is completely worthless to me now, please help me fix what I have done!!
