Hey, you can follow the steps below to fix your Windows boot problem:

Step 1: Insert a blank CD into your computer. Download and launch Tenorshare Windows Boot Genius on another workable computer and click "Burn". Only one click of mouse, you can finish burning a boot CD.

Step 2: This step is operated on the computer that won't boot up. Insert CD onto your computer. And set BIOS to boot your computer from CD, instead of hard drive. It will reboot automatically and access to the CD.

Step 3: Then you will load to system. Launch this program under Win PE. Select "Windows Rescue" to follow the built-in wizard to fix the back screen problem.
