It will get to around 50 percent during the setup is copying files and it says cannot copy file. I have 3 different disks and it is still doing the same thing.

Could this be some hardware problem? Before it would just restart when it would restart when it got finished loading up windows.

Did you completely remove the partition and re-format? Don't forget that you will lose ALL data on the drive if you do this.

I've had that problem lately and for me it came out to be a faulty harddisk.
So I'd like to know the answers on Hengis' question too, as I was unable to format that harddisk too.

I only had time to do the quick formats. Should I have done the long one? Usually the short one will work and it will install. Each time where I got stuck it was always different files and even if I skip the file the following file could not be found. I think the HDD was bad.

I'd suggest you to try a long format, yes.
