    It is already set to active, and just thought to mention that none of the partitions seem to have drive letters. Anyway, everything under the Disk tab is greyed out, so I can't do Rebuild MBR.

    Boot back into Repair Command Line and run "bootrec.exe /fixboot" and "bootrec.exe /fixmbr" or if those don't work "Bootsect.exe /nt60 all /force".

    If this will not force WinRE to see the installation, try running Startup Repair x3 anyway.

    If that fails, what I would do now is make a small partition at the front of your HD to install Win7 upon, at startup install EasyBCD to Add OS, selecting Win7 and the stranded partition's drive letter. Restart to see if you can now boot it. http://neosmart.net/blog/2010/welcome-to-easybcd-2/

    We will help you later remove all of the files except those for booting on the rescue install, shrink the partition down to around 200mb to serve as a boot partition, then Resize Win7 into the rest of the recovered space.

    I would wait til morning to see what BareFootKid has to suggest since you are using his tutorial to recover deleted XP space into Win7 install.

    I'm sorry but could you be a little more detailed as to how to use EasyBCD? The documentation is not very helpful in this. And by install do you mean boot from a disk? Because right now I cannot boot Windows 7 due to the missing bootmgr error.

    Here's how to add using EasyBCD, though this says Vista it's the same.

    Yes, boot from the disk to install Win7.

    Alright, so now there seems to be a problem. Now when I try /fixboot and /fixmbr they both give me "The system cannot find the path specified." the Bootsect.exe part seemed to have worked, since it gives a "Bootcode was successfully updated on all targeted volumes." But I still can't see the installation. So I try running Startup Repair. But now Startup Repair gives me a "Startup Repair cannot repair this computer automatically" error. Here's the problem signature.

    Problem Signature:
    Problem Event Name: StartupRepairOffline
    Problem Signature 01: 0.0.0.0
    Problem Signature 02: 0.0.0.0
    Problem Signature 03: unknown
    Problem Signature 04: 0
    Problem Signature 05: unknown
    Problem Signature 06: 1
    Problem Signature 07: unknown
    OS Version: 6.1.7600.2.0.0.256.1
    Locale ID: 1033

    So then I used Partition Wizard to create some free space at the front of my HDD, then tried installing Windows 7 on it. But after I click "install now" it gives me

    Load Driver
    A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.

    It seems that all this happened because I marked my Windows 7 partition as the boot partition. Could I at least be able to boot in to 7 again if I make Windows XP active?

    Your problem suggest you need to rebuild your BCD. You were probably originally booting through the XP partition.

    Do the following from the system repair disk command prompt.

    >bootrec /scanos
    This should come back and identify the Windows 7 OS partition.
    then
    rebuild the MBR
    >bootrec /fixmbr
    then
    Fix the Partition Boot Record/Boot sector.
    >bootrec /fixboot
    then
    importantly, rebuild the BCD
    >Bootrec /rebuildbcd

    Alright, I tried it, but /scanos returns 0 identified Windows installations.

    When you boot the system repair disk it generally also has a look for an OS - does it find one?

    Anyway try the other 3 bootrec commands. The BCD rebuild is important and shouldn't succeed if an OS isn't present.

    fixboot and fixmbr both return that the system cannot find the path specified. rebuildbcd also scans for windows installations and finds none.
