I started this operation having a dual boot up system using two internal HD's, one running a 32 bit Win7 home addition the other a 64 bit Win7 Ultimate.
I was running Win7 32 bit on one drive which I needed to run my old version of Autocad, the Autocad is installed on an external drive. Because I had nothing of importance on this drive I did a clean install and it worked perfectly, in fact I was more than pleased with it's performance.
I wanted to upgrade my 64 bit drive to win10 64bit and I have now tried five times and each time it arrives at the welcome page and when I press next the wheel just keeps spinning and going no further. I have left it spinning for up to six hours without a result and then ended up doing a restore.
I have tried to repair via "other options" but that freezes on the select keyboard page on all of the options available, so I end up rebooting on my cd repair disk and running restore.
I have stripped the system of all add on hardware leaving just keyboard and mouse on the last three occasions.
I could obviously stay where I am BUT I feel I will gain a lot by upgrading from my experience with the 32 bit Win10.
Any advice would be very gratefully received
