So basically I managed to clean install a new Windows 7 OS on a Western Digital ATA HDD through a desktop. After being able to also set it up as a slave drive to access files on my Windows 8 Laptop, I wanted to see if the laptop could also boot Windows 7 as a USB. I went into BIOS and enabled Legacy Support and changed Boot Order to USB. Then I tried to load windows 7 and it would give me the bluescreen with the 0x07B error. Needless to say I searched around and found I needed a program called PWBoot to enable USB loaded onto the HDD. Now the Windows loading screen completes all the way instead of cutting halfway, but it still gives me the bluescreen for 1 second and then restarts to give me windows repair. However the repair is only windows 8, I will need to use my windows 7 repair disk. ANY HELP WOULD BE APPRECIATED!!
