    I have had my Windows partition for awhile, and I was moving just fine. I booted into Mac to make a new partition. I click my Mac HD, and hit the + and created a new partition. I installed whatever onto that partition, and then deleted it. I now can not boot into Windows anymore. The drive is not deleted, it is still there and shows on my desktop, Boot Camp Assistant detects it, I can set it as the boot device in System Preferences but if it is the main boot device it says no booatable device found (The black screen DOS like interface). If I boot my mac and hold down option, the Windows partition doesn't show.

    Any help?

    Part of what Boot Camp does for you is to "wrap" the Mac's native GPT partition scheme so that it looks like MBR (the legacy scheme supported by Windows).

    Creating the new partition has confused this translation. You may be able to fix it with tools available from rEFIt (even without installing rEFIt).

    You might also be able to use W7's repair wizard to fix your booting issues assuming that that is the version of Windows you have installed.
