Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
The new windows 10 license you purchased, where did you p urchase it from? What version of windows 10 is it for?
Also, did it ship with a DVD disk or a download ?
Ok, on the receipt, what version of windows 10 does it say its for.. Home, premium, etc?
Also, does it say whether its an upgrade or a full version?
And, did it include a disk or a download ? If you arent certain, we need to check your email receipt.
Allright, whether or not you can find the receipt, let me know!
Allright.. What we may need to do then, is utilize the download ( ISO file ) they sent you.
Properly burn that download to either a DVD or a USb using a special tool.. Then, boot the computer from that DVD so it can install the exact version of windows 10 you purchased. And then, your license key will work.
So the question is, do you have another computer available, and do you have a spare USB memory stick or DVD r or rw disks?
Allright. We need to download the file they linked you to in the receipt email.. It should be an ISO file.
Once downloaded, let me know if you have access to a usb memory stick, or a blank dvd r or rw disk so we can properly burn the image to the disk so its bootable.
( unfortunately, your hard drive wont work, as we need to format the drive and make it bootable)
You cant drag the iso file directly to the drive..
We have to use a speccial tool to burn the ISO file to the drive.
This page, shows the steps and contains the link to download the USB creatioon tool
We have to download the iso first.. Save the file.
Then, u se this tool to write that iso file to the usb.. If you get stuck, let me know.
Apologies for the delay..
If there isnt enough room on the USB drive, then it wont work.. Did you find a larger usb drive?
If so, then we need to use the USB creation tool I linked you to, in order to burn the ISO image to the USB and make it bootable.
( you cant just copy and paste, that wont work )
To be clear.. we dont download the media creation tool onto the usb.
A.. Download the windows 10 ISo file to the computer( from your microsoft receipt )
B. Download the usb creation tool to your computer.
C. run the media creation tool, tell it to create a USB using the ISO file.
D. The USb creation tool will then properly burn the file to your usb drive, formatting it, and making it into a bootable windows installer.
Have we done those steps precisely?
Understood. In that case, the link below may be of interest to you.
