if it asks for a key during the install, most likely it thought you had a non genuine copy of win7 installed. did your copy of win7 come with the computer?
Five days ago, I finally decided to jump and install Windows 10 on my Windows 7 computer. I have had pop-ups inviting me regularly.
What a mistake!
I have prepared myself with the cloning of my hard drive on a new hard drive.
I started the installation process. First problem, it could not install. I tried four times. Then I found on the web that I neede to install while the computer was in safe mode, for minimal interference with other programs.
Finally it started the installation process until I got to the product key input. I tried my Windows 7 PK. Wrong.
I called Microsoft support. They wanted to sell me the licence. What? I thought it was free upgrade!
Apparently, I did something wrong.
OK, then forget about it, I will stick with my got ol'Windows 7.
I hard a hard time getting rid of the Windows 10 installation process., and I had to reinstalled my Windows 7 (Legal,if anybody question that!).
The boot process got screw up.
The installation also hit the fact that my hard drive was either MBR, or GPT, or EFI,, anyhow, the wrong one.
In the meantime I called several times Microsoft support, and following their suggestions. It got worse.
Eventually I had to reformat the hard drive so it would accept the Windows program. Strangely, I ended up with a basic Windows 7, without mouse, and internet access!
Call Microsoft, no joy!
And, when I call Microsoft support and I am on hold, they claim that Windows 10 is easy to install!!! What a piece of crap!
So, after 4 days, yes 4 days full time, I cannot install on my hard disk, so I connect my new clone hard drive, but could not access it!
So I tried to install Windows 7 on that new drive. Again the drive is MBR, or GPT or EFI or whatever!
With a software downloaded from the net, I try to reconfigure the drive, bad idea, my clone drive is formated!
And worse, I still can<t install Windows!
Let's talk about Microsoft support, they are totally useless. I ended up in Asia when speaking english or in Morocco when I tried in french. Except for one time, the line had a lot of noises, and those guys in Morocco must have had potatoes in their mouth.
They even offered me to google, or go to youtube.
By the way, I am using another computer (small notebook) to rant. I am also invited to upgrade to Windows 10 on this notebook, but pîg will fly before I do it.
