    As far as I know bcd (bootmenu) is working and you did rebuild it. Say C is writable. Bootsector should only read bcd and bootmgr. Maybe bootmgr problem??

    Code:
     
    attrib  -h  -s  c:\bootmgr
    del  c:\bootmgr
    perform startup repair now. bootmgr is back now?

    Code:
    attrib  c:\bootmgr
    try to reboot normally

    is there a way I can just get rid of everything on the harddrive and then install windows 7 fresh or will it still not have all the boot files?

    The flags you should be looking for to show you've successfully moved the boot files are System Active, not Boot. Boot only signifies which partition you are booted into at the moment.

    In addition if you installed Win7 from the old partition and not from the booted installer, then it would not be lettered C, so you may have deleted the new Win7.

    In your case you have a 400mb hidden partition which Diskpart says is labeled System. This is likely an OEM partition intended to boot the system.

    Mark WIn7 Partition Active and run Startup Repair - Run 3 Separate Times until Win7 starts and holds the System flag, as should have been done before deleting the old Win7 partitition.

    If this fails delete all partitions in a Clean Reinstall - Factory OEM Windows 7.

    just do:

    ren c:\bootmgr c:\bootsave

    and perform startup repair
    then reboot normally.

    Still failing with same error?

    you can. But you have a RECOVERY partition (to restore to factory settings). And a DATA partition. DATA partition has important files I assume?

    I gave you the boot repair steps earlier to try after checking your HD. Additional measures are in step 8 here: Troubleshooting Windows 7 Failure to Boot

    Rescue your data using Copy & Paste - in Windows Recovery Console or Paragon rescue disk; change drive letter; recover data.

    You can try also running Recovery from it's hotkey at boot: Toshiba HDD Recovery Utility

    However a Clean Reinstall - Factory OEM Windows 7 is a vastly superior install. Everything you need is in link.
