Windows 7 installation failure.

My windows got corrupted.
I cant boot or do a system reset.
Dont have a dvd drive in this case.
So i tried to install windows 7 with usb.

Everytime i try to install it i get an error saying "cd/dvd drive device driver is missing."

I tried my existing product key to get a iso from microsoft. This didnt work.
So i even bought a new licence code online to get a new iso to burn to my usb. This also doesnt work.

I recently upgraded to a new case, motherboard and cpu.

I have no idea hoe to fix this.
Anyone that could help me solve this?

Thanks.
 
Solution
Make sure you are using a USB 2 port to install Windows. If it's a newer system you may need to download the USB drivers for the motherboard and point the setup to that or check with the motherboard vendor support.
