Windows 10: Buying Windows 10 Pro license key without Installation disk or USB

How can I buy only Windows 10 Pro license key without Installation Disk or USB?

:)

 

Installing windows off of a USB stick

Step By Step from vista:
From admin cmd prompt

1. diskpart
1a. list disk
2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)
6. active
7. format fs=fat32
8. assign
9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

 

I'm trying to install windows 10 in new computer from USB drive.

I don't really understand what you're saying.

You have two options:

A) Have a previously licensed version of Windows 7 or 8 on a PC, run the GWX upgrade to Windows 10 (which then swaps your Windows 7/8 key to a Windows 10 license), then do a clean install and Microsoft will automatically license that PC provided the motherboard is installed.

B) Have a Windows 10 license, install Windows 10 on the PC as a clean install, and input that license.

 

Question On OEM Windows clean install......

"Flavors" of Windows licenses

Windows can be a little "odd" about license keys. There are at least 4 categories:

• Retail
• OEM
• Volume (electronic download)
• Corporate (no key needed)

For guaranteed success, the license key and media should be in the same category. If you have retail media, you may not be able to install it using an OEM or Volume license key, even though the key is valid for that version of Windows. *Wtf :wtf: Apparently, this is part of Microsoft's anti-piracy scheme (i.e., all customers are guilty until proven innocent).
