Hi guys, I just upgrade my pc as in new motherboard and processor.

Asus P5KPL-C/1600 to Asus H110M-D
Core 2 Duo to i3-6100

Unfortunately, during the installation of window 7 using USB drive, it keep on showing "A required CD/DVD drive device driver is missing".....

Thus, I went to google it and try several method such as change the USB stick to another port... the problem still goes on... further, i discover that this new motherboard is running UEFI (i not sure what it is) then i did tried the UEFI bootable USB flash drive method.. and then it became "Window failed to start. A recent hardware or software change might be the cause" and i totally cannot install window 7 at all now..

Can any expert help on this problem? (Sorry im a noobie of pc)

How do i get Window 10 Files and copy into USB?

Okay, i try to download 1st and see whether it work or not, thanks first

I tried to install window 10 which run smoothly, just the matter installing window 7, so i asked and someone told me have to modify system file, i have no idea lol
