Can't install windows 7 64bit

Hello all , I decided to register with this forum , as i'm having trouble installing windows 7 64 bit . I'm on windows 10 64 bit at the moment , I'm not too techie smart . I built this computer after watching someone on YouTube and taking the specs of the Motherboard , Ram size i7 from a high spec gaming computer on Ebay .It works . I'v tried burning the windows dvd to disc and when I put it in the dvd drive I get a few options , what do I want to do with this dvd . Which includes options to open the exe file , but when I disconnect this Harddrive ( I have 2 harddrives ) it won't install . I burnt it onto a USB Flash Drive with another version of windows 7 but same results everytime I,v tried . i'v tried burning with IMGBURN , ULTRA-ISO I get load exe file but not on the drive I want .I downloaded the ISO file from Getintopc.com and its a windows 7 64bit . I have tried 2 different hardddrives and I think at least one of them has had windows on before. I don't know if I need drivers to help it install or what . I think before i'v just burnt the dvd on nero or something similar and it's loaded . The drive is a 2TB drive Thank you very much for any help NettleWarbler .

Hello AddRAM , I tried putting the burnt dvd in the dvd drive to see what would happen I got the choice to install the windows dvd . So I thought when I disconnected the windows 10 drive and booted up it would install on my newly formatted drive , but no such luck . that was why I mentioned "open the exe file", I just thought it would work properly and install ..

It says reboot and select proper boot device or select any key

Right that dvd was no good , this other I did gives me the Run set-up.exe option . any advice for this don't say Set the bios to defaults by hitting F5 then F10 to save and exit before you start. because I don't know if I do that before settings , in settings or after settings.

I do get the words reboot and select proper boot device or select any key Press any key to boot from DVD

That sounds like you are in the Boot menu maybe? After re-setting the bios. Or got into the boot menu instead of the bios maybe. Laptops vary as to which F key to press for boot menu or bios, but F2 is often for bios and Escape is often for Boot menu. Anyway, if you get into the bios and do what AddRam says, then use the arrow keys on your keyboard to go along to exit, hit return, say yes to changes and the laptop should then just start up again and have nothing on it, so then you can turn it off, put the Windows dvd in the drive (or usb), turn it on, and you should get to the screen that says hit any key to boot - and it will starting installing Windows. If it's a usb, you might need the boot menu to select the usb stick to boot from and then you'll get to the same thing - hit any key to boot - and it'll start installing.
