Hello, I am just getting done with college and have a lot of knowledge and experience with hardware and software troubleshooting in Windows and I have always wanted to start a business so I figured why not a computer repair business. I am trying to figure out everything that I will need and I have run into a problem. I am sure I will come across, for example, someone with a Dell pc that does not have a recovery disk. In this situation what exactly would I do? Do I need to get a disk from every manufacturer for every version of windows? Would a basic OEM disk, for example, xp home work for any OEM pc like Dell, hp, Compaq, etc? I was just wondering what Windows disks I am going to need to have on hand so I could prepare myself and get some of this stuff in advance before I get my business up and running. Thanks in advance.
