Ok, I know I completely messed up here and it's all my fault, but moving past that -- can anyone help me fix this situation?
I used Boot Camp to install Windows 7 on my MacBook the other day. Then, unsatisfied with the amount of space I'd allocated for this partition, I shrank my OS X partition by a little and tried to expand my Windows partition to include the unallocated space. Of course that didn't work, and I found myself playing around with EaseUs to see if I could make anything happen. Click, click, click, and before I knew it I'd turned my OS X partition into unallocated space.
However, I can still access my home directory (and other system files, which I haven't touched) on the OS X partition via Windows! I have created a manual backup of the files I deem important, in addition to have a pretty recent Time Machine backup. But when I try to have the Boot Camp util restart the computer in OS X, it says "Could not locate the Mac OS X boot volume". And when I restart Windows and hold down the alt key so I can choose my startup disk manually, the only startup disk that is found is Windows.
Can anyone please help me understand what I did and how I can fix it, preferably without having to erase my Windows partition and do everything all over again?
