i just upgraded to windows 10. i have an older custom built pc.that had windows 7 on it but after i used a usb to put 10 on it wont boot. it says “no boot device found” help please i cant buy another computer

If you previously had Windows 7, your boot options in your bios settings are probably set to Legacy. Try switching them to UEFI and seeing if it boots.

Sounds like something went wrong during the installation. Did it get this error during the upgrade or was it able to boot into windows 10 before?
