I had tried many times to upgrade to windows 10 and it consistently failed.
It was so bad I figured I just turn that netbook into another Linux machine.
Finally I figured out the answer:
From a windows machine (not linux) go to https://www.microsoft.com/software-download/windows10
- download the the media creation tool. (won't show for linux machines)
The next step is important.
You have to be admin (running tool as administrator will not work).
- save it to your drive where you know it will be.
- What I did was change my login to admin (control panel -> change users ->change type). Or possibly you could just login as admin but I did not do this.
- Restart the computer and login as yourself (now that you are admin, or try admin login).
- Plug in a USB drive with 4 gigs or more (it will erase anything on the drive.
- Find the file you downloaded and run it (no need to run as administrator as you are admin).
- Then follow the instructions, you should already know if your computer (Start -> computer -> properties) is 32 or 64 bit as that is what you need.
It will create a bootable install disk or usb for you.
When it's finished,
- you simply start up any computer you want to upgrade,
- insert the usb stick,
- browse to it and find the file start.exe
- and run it.
- Then follow instructions.
I've used it on a windows 7 Starter netbook, and a Windows 8.1 tablet.
Once it is installed it will ask you configuration questions like default applications, on the left side is a tiny link allowing you to customize your choices, good if you like privacy.
You can use this for upgrade or fresh install (with your product key), I only used it for upgrade as I wanted to keep my files.
