Auugh! My boot drive was changed by MirrorFolder

I hope someone can help me. I needed a good backup program so I downloaded a trial of MirrorFolders. I have two identical 750GB drives in my laptop: C (my main drive) and Z (my backup drive). MirrorFolders made an identical copy of C onto Z. That wasn't what I really wanted, because C is partitioned into D and E, and MirrorFolders didn't mirror the other two partitions. The backup methodology wasn't exactly what I was looking for, so I uninstalled the program. After uninstalling MirrorFolders, the machine is now booting to the Z drive, which means I can't format it and try another backup program. Is there a simple way to restore the bootability of my C drive? I read a great deal about copying boot folders and such, but I wasn't exactly sure if these were the right answers and I didn't want to screw things up any worse. I figured I could go into the BIOS and disable the Z drive, but no luck. The machine couldn't find a bootable drive, even though C supposedly has the same files as Z. No answer from MirrorFolder's tech support, so I thought I would ask here and hope someone can fix the problem. Needless to say, if anyone wants to use MirrorFolders, they might want to think again.

I was afraid that this wasn't going to be simply a matter of copying a file or two. I would like to do unkind things to the developers at MirrorFolder. Ironically, I downloaded the Easeus trial too--just happened to install MirrorFolder first. There's a gui for bcdedit called easybcd. Is this any good? I am really frightened of doing harm to my C drive.

I went through all the pages, and most of the stuff was inexplicable--what the heck is a UUID? Where do I find it? Why is this so complicated? Will this work, do you think? bcdboot c:\windows /s c:

Okay, I ran Recovery. I tried BCDedit. I tried BCDBoot (bcdboot z:\windows /s c). I ran my system recovery disk that I made first thing.

Nada. Here's the info from BCDedit.

I am now frantic. Can someone pleeeeze tell me what do do next?

Okay, the second time I ran Repair, it worked. I am back to normal.

And so, um, can anyone recommend a good backup program that will mirror drive c to drive z without making a horrible mess?
