Suggestion computer problem

A while ago my computer was repaired . According to the repairman the power supply was gone and destroyed some other things too.( It's running now on a external sound card and internet adapter) Although I gave him my genuine window 7 starters set up disk, he put in an illegal window 7 ultimate . There are two 250 Gb each hard disks in the comp, one (D) is empty, everything runs on the other one (C) My question is : Can I download my genuine window 7 on this empty (D) disk , try out or this works and if so than getting rid of the illegal one by formatting disk (C) ???

 

Yes.

Install more than one operating system (multiboot) - Windows Help

 

Thanks a lot, Dude & Robert, for the quick reply. Great help.!!

 

My suggestion is that you avoid the dual boot stuff if you don't really plan to dual boot the system in the future. Make copy of your personal files, then just disconnect drive with illegal operating system and connect drive without operating system and install operating system on that drive. Run on one drive. If you like it, connect the other drive to system and format it and restore your files.
If you don't like it, plug in the old drive, boot from it and format the drive you recently installed Win 7 on. My bet is if you are comparing Win 7 and Win 7 Ultimate, you won't notice any difference unless you are a power user. If you gave the repair guy your media, I assume you don't have your license key. On most laptops, the license key is stuck on the bottom of the unit. If you have a desktop, I don't think that is the case. Before doing anything make sure you have the original software license key.

 

I have Dell, HP and Samsung towers right now and all have a windows COA sticker on them. My laptop doesn't because it was Linux originally and I installed windows after and the COA sticker is on the case with the disc.

 

I stand corrected. Haven't owned a factory built desktop in forever. Microsoft authorization sends the configuration of the computer it is installed in. If it's significantly different you may need to call them. When I moved from VMware fusion on my Mac to Parallels I had to call MS to get the license code to work for my Win7 VM.

 

Strangely enough I don't own any computers in their factory configuration but I find it convenient to let the vendor gather most of the parts.

 

Problem with buying a prebuilt system which is what usually comes with these *starter* editions if often the starter edition is limited use to that motherboard or cpu type or configuration. Changing out CPU and/or Motherboard can result in a windows starter edition no longer being able to install as they are generally factory OEMs that get locked to specific hardware.

This may have been the issue on why your tech installed a pirated copy. Further though the registration key often is also locked in many ways to OEM computers as well that it only works for that specific install disk batch so using it on another install from a different disk that isn't the same batch type won't work.
