I get to the advance boot menu of my windows 8 laptop, select boot from USB and go through putting in my product key and then I select UPGRADE not CUSTOM. it then proceeds to give me this message:
"The computer started using the Windows installation media. Remove the installation media and restart your computer so that Windows starts normally. Then, insert the intallation media and restart the upgrade"
So following the instructions I remove the USB and click close in the bottom right of the window, and then another window flashes too fast for me to read and then takes me back to the original windows set up screen with the big install now button. I then exit out of this window and confirm I want to stop the installation. At this point the USB has been removed and the laptop restarts. Am I supposed to put the USB back in while it is restarting? When I land back on the home screen I repeat the process of holding shift and restarting and selecting the USB to boot from and the vicious cycle continues. I really don't want to have to do a fresh install of windows 10 as I don't want to lose all of the files. I can back everything up worst case scenario but I would like to just upgrade as I never received the upgrade sign in the bottom right months after windows 10 was released, so I took it upon myself to make an ISO. I really appreciate you reading all of this. I am just trying to be as thorough as possible. Thanks for the help
