We can fix this problem but like i said it will take some time to fix this problem sorry there is no easy way well Startup Repair if it works is the only easy way.
Restart your computer and press the appropriate key to enter the BIOS or UEFI firmware settings screen while it boots. This is often the F1, F2, Delete, F10, or F12 key. Consult your computer’s manual for more details, or just perform a web search for your PC’s model name and number as well as “enter BIOS.” From Boot tab and from Boot Device Priority section or screen move the Windows 10 USB flash drive to the top of all other devices it should be listed as a first boot device.
What is your manufacturer name, model number?
