I'll try to explain the issue in the most detailed way I can:
Heres the issue:
Dell Laptop With pre-installed Windows 7 64-bit. Used the Windows 7 for a while but wanted to start using Windows 8.1. So I made 3 partitions out of my 1 harddrive. Resualting in 1 disk C: With Windows 7, one disk for D: DATA and then a empty one where my E: Windows 8.1 installation would be.
Installed Windows 8.1 into the E: drive and enabled Dual boot. I got the new and fancy Windows 8.1 / 2012 boot menu and everything was working fine. Switch the primary boot selection to Windows 8.1 and I started using it. At the time flew I only used my Windows 8.1 and since I didnt have any important files on the Windows 7 drive I decided too format that drive too free up some Space. I probably shouldnt have done that. When i tried booting after I formatted the drive I couldnt boot at all. I got the warning that the system couldnt find any bootable Device and i should try deattaching any other harddrives etc etc.
So i figured that I had screwed things up so I installed WIndows 7 again on the drive I formatted, and got to boot and my Windows 8.1 drive are still there With all the files, so all good. But now I dont get the option to choose my Windows 8.1 when booting.
So the question boils down to this, is there any way to fix this? Can I make Windows aware of my existing install so I can boot into my Windows 8.1 again?
Optional: Lets say I can Windows aware of the Windows 8.1 partition and fix the dual boot. Is there any way to make that THE one and ONLY primary disk so I can remove the Windows 7 installation and only use Windows 8.1?
Any advice would be be highly appreciated since this is my work Laptop and i kinda need it up and running this weekend.
