Windows 7 Boot Error 0x0000007B

I fear I've messed up and hope this can be resolved. Here is the video of what happens what I boot my computer. The boot sequence gets to the Windows logo and then crashes with the error shown above in the title.

I tried the solutions on HowToGeek however, none of the commands bootrec /fixmbr & bootrec /fixboot worked. I have tried safe mode, repair on local & USB Windows 7, yet still no fix. The additional issue is that when I load up Windows 7 Bootable USB, the OS fails to find any hard drive!

The following image shows that the system recovery doesn't find any Windows installation either.

Notes:
I was fiddling with the Windows 7 Disk Management making space for Ubuntu before this happened. I initially shrunk the C (primary) drive partition, then later remerged (extended) the C partition to include the newly created empty partition.

I really do not want to lose the data on C !

I had this same problem. Changed SATA Mode in BIOS from AHCI to ATA, and it booted right up. Dell XPS M1300.
