Windows 10: Upgrade From Dubious Windows 7 License to Legit Windows 10 Pro

My son recently brought over a dead PC ( fried PSU and fried additional HDD). I was able to get a good Corsair PSU on sale and removed the dead HDD, leaving the boot HDD in the pc. The computer booted into Windows 7 and so I decided to use the creation tool to upgrade it to Windows 10 pro and purchase a key. As Windows 7 was not legit, the tool refused to upgrade to Windows 10. I figured no biggy, I would just use the tool to blow away whatever was on the HDD as all the data was backed up. I started the computer and selected the USB stick as boot device but instead the computer booted into Windows 7 and now I got the message that Windows 7 needed to be repaired. This was unsuccessful as the license wasn't legit and so I restarted the pc, again I selected the USB drive by pressing f8 and this time the selection screen for windows showed up with the options: "Start Windows 7 Normally" or "Attempt to Repair Windows 7". I really had no desire to attempt a repair which was pointless in any case so I googled for the issue, no joy. I could have pulled the HDD and put in another but I was determined to use the existing drive. With a wonky Windows 7 install, troubleshooting the drive was not an option. So, what to do? I installed Linux Mint on the drive, took all of ten minutes and blew away the troublesome Windows 7 install. Once that was done, the pc now booted into the media drive, and I was able to install Windows 10 pro, I purchased a license and all is good. While this was successful, was there anything that might have made this a bit easier? Other than a new drive? I just cannot figure out why the computer kept booting into the Windows drive instead of the USB stick. The computer is an older home made build, with an ASUS M5A78L-M/USB3 MB.

Windows 10 upgrade license

Ahem... lost my activation when upgrading from AMD Phenom II to my XEON...
Installed "legit" activated Windows 7 Ultimate x64, and yes i paid for the license originally, but that key no longer works.. i paid more than enough to MS *Shadedshun :shadedshu:
Anyway once 7 is installed.. go here... Download Windows 10
Click Upgrade Now, it will give you a download with an app that gives you legit activated Windows 10 based on your Win 7 activation.

 

Windows 10 upgrade license

Hello guys,

I have 1 license of WIndows 8.1 FPP/retail license. I want to upgrade to WIndows 10, but I one thing is unclear to me.
If I upgrade, will WIndows 10 license be retail or it will "turn" into some sort of OEM license?

I ask this because I upgrade my PC, you know, more memory, replace HDD, and I intend to upgrade the MB and CPU to Kaby Lake platform sometime in the future, (and of course sell the replaced hardware)
This thing is not clearly mentioned anywhere.

Thank you.

 

Windows 10 upgrade license

The interesting question is that: the upgrade takes place before 29 of July. If I upgrade the PC (change the MB), and I transfer the Win 8.1 license to this new PC (cause 8.1 is retail FPP), will I be able to upgrade to Windows 10 for free? Or a upgrade license must be bought?
