Windows 7 won't boot, cannot be fixed in winRe, Also in a dualboot

My computer is setup to dual boot with Windows 7 64 and windows Vista 32 (original OS it was "born" with). Both OS runs with no problems for months too. Anyways today, I was going trying to boot into windows vista to use some program installed in the OS, but was a bit too late in choosing the OS from the bootloader screen. In the panic to "pick" the OS, i accidentally place my slightly heavy headphones on the power button (lol/facepalm) while it was starting to boot into windows 7. The computer turned off, of course, interrupting the boot process. I turned it back on and booted into vista to do my business...

Later on, I wanted to go back to my Windows 7, it failed to boot, and WinRE tried to fix it. It rebooted a few times and just kept at it to fix the problem until it says it can't fix it. Here's the report it gave me:
Problem Event Name:StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: -1
Problem Signature 05: Autofailover
Problem Signature 06: 1
Problem Signature 07: NoOsInstalled
Os Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033

Also can't help it notice that it refers to my windows drive as 'E:' which was supposed to be 'C:'. But I have multiple partitions in my master HDD so its prolly just labeling it intrinsically.

Also safemode just loads winre.

It was kinda a bit of a pain to reinstall the whole crap with the 64bit drivers and some registry tweaking to reinstall windows 7 so I just want to see if there is a solution I wasn't able to find in Google.

I dualboot Windows vista 32 and Windows 7 64. One day while loading windows 7, the power was interrupted and win7 wasnt able to load anymore so startup repair did its business. It restarted a few times till it says "Start up repair cannot automatically repair this issue" with the following errors: "Autofailover", "NoOsInstalled', and "No OS files found on Disk. repair action - Partition Table Repair". I also tried the safemodes, Last Known good configuration, and also restoring to previous restore point (which did not find any restore points at all) and none of these worked--it just starts Stat up repair. I was able to still boot into Vista with no problems and used it to check my BCD:

Code:

Name:  Windows 7
BCD ID:  {default}
Drive: \Device\HarddiskVolume3
Bootloader Path:  \Windows\system32\winload.exe
Windows Directory:  \Windows

Entry #2

Name:  Microsoft Windows Vista
BCD ID:  {current}
Drive:  C:\
Bootloader Path:  \Windows\system32\winload.exe
Windows Directory:  \Windows

I noticed windows 7 uses HarddiskVolume3 which I checked with DISKPART as actually the "Vista recovery volume" from the manufacturer. Is this the problem why it can't find the OS and the restore points?

I'm kinda careful to edit the BCD because I might screw it up making vista unbootable too. I'm not too experienced in this area.
