Windows 7: Windows Boot Manager FAIL!

Windows Boot Manager FAIL!

Hello Everyone.

I had a dual boot with Win7 and Win8. I wanted to remove Win8 cause I was bored and didn't need it. So I used a method on this forum.
I did everything right.

Dual Boot - Delete a OS

But the boot manager failed. When I restarted I got an error saying that their is some invalid information.

I didn't have the Win 7 disc, so I put the Win 8 disc and installed it in the partition that had win 8 before, hoping that it would recognized Win 7. But hasn't.

So now I have a partition of Win 7 but it is not getting recognized. Is there any way to help this?

Please post back a screenshot of your maximized Disk Management drive map and listings:

1. Type Disk Management in Start Search box.
2. Open Disk Mgmt. window and maximize it.
3. Type Snipping Tool in Start Search box.
4. Open Snipping Tool, choose Rectangular Snip, click New, draw a box around full drive map and all listings.
5, Save Snip, attach using paper clip in Reply Box.

Tell us what is on each partition. We will tell you how to make Win7 bootable on its own so you can delete Win8 partition when ready.

To create a Dual Boot install EasyBCD (click Download - no Name or Email required) to add Win7 on Add OS Entry tab.
