I'm not too experienced with computers in too many ways, and I'm also not too sure if this is the correct place to ask this.
So, today I was trying to use a bootable USB to install Windows 7 Home Premium x64 on a refurbished HP Stream 11 which had Windows 10 Home x64 installed on it. Everything went well once the installation began, so I decided to just leave it be. Last I saw it before it all went down was during the "Expanding files" point of the installation. When I returned about half an hour or so later, I had the message about needing to shut down the computer to prevent damage. I'm not sure what to do, or if I should boot to the USB or SSD right now. That is my question. Could the installation have finished, but then somehow crashed the computer? I am not sure, as Windows 7 was very stubborn and it took a while to get the installation started. It only ever began once, and it was when running the setup.exe from the OS, not booting directly to the flash drive. Should I try booting to the hard drive of the computer, or would that fail? I'm mostly expecting that I should reinstall the laptop's original operating system, but I wanted to get help from more a experienced person first.
UPDATE: I attempted to boot from each possible device (Hard Drive, Windows 10 installation USB), but for some reason they're all connected to Windows 7. It seems that Windows 7 installation went wrong soon after the files for start up were added to the mix, so now it just does Windows 7 "Starting Windows" and soon after it gets the same blue screen. I'm not really sure what to do at this point.
