Cannot Boot Into Windows 7 / File /boot/BCD Is Missing With An Error Code Of 0x0000007

I cannot boot into Windows because it says that the file /boot/BCD is missing with an error code of 0x0000007. If I run Repair from my installation disk and in System Recovery Options, it says that it has detected problems and asks if I want to repair it. The items it wants to repair are: " The following startup option will be repaired:Name: {bootmgr}Identifier: {9DEA862C-5CDD-4E70-ACC1-F32B344D4795}

The following startup options will be added:

Name: Windows 7 Ultimate (recovered)
Path: Windows
Windows Device: Partition=C: (476938MB)
Name: Windows Recovery Environment (recovered)
Path: Recovery9426aa67-30ff-11e0-a348-506313b5e718Winre.wim
Windows Device: Partition=C: (476938MB)

A copy of the current boot configuration data will be saved as C:BootBCD.Backup.0002"If I click yes, it says that it cannot save the current settings for the BCD and refuses to continue. When I choose Startup Repair, it attempts to fix the problem but fails.

The problem details are:

Root cause found:
No OS files found on disk.
Repair action: Partition table repair
Result: Failed. Error code: 0x3bc3

I think that this is because Startup Repair is trying to fix the thumbdrive that I keep my Windows 7 install files in. I am overseas now and as my computer does not have an internal optical disk drive and my external drive is back home, thus using my thumbdrive is the only way to access the repair console.

I tried running a few commands, namely:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Fixmbr and fixboot work, but when I run RebuildBCD, it detects C:Windows as having a Windows installation, but if I type Y(yes) or A(all), it says that the requested system device cannot be found.
