I bought an HP with Windows 8.1 installed. I put in a second hard drive, unplugged the drive with Windows 8 installed, and installed Windows 7 on that drive, then plugged back in the Windows 8 drive.
I installed EasyBCD in Windows 8 and did my best to remove all the non-essential drives, and left Windows 7 & 8, with Windows 7 at the primary boot. I also disabled a few things in the BIOS which I've read on other posts, enabled legacy, etc.
Sometimes I will get the GUI boot manager with Windows 7 & Windows 8 listed. If I choose Windows 7, it goes to the black & white boot manager, with only Window 8.1 listed. Other times it goes straight to the black & white boot manager, with only Windows 8.1 listed.
How can I get it such that both OS are listed, and, I can boot into one or the other? A couple of times I messed around with some boot settings and other things and was able to boot into Windows 7.
But, I just want a boot manager to list both OS and allow me to boot into either one.
Any help would be appreciated.
