BSD during windows update, now can't start OS & have no repair disc

My Window 7's files got corrupted after a blue screen interrupted the update process, and I don't have a recovery or installation disc at the moment.

This nuisance occurred during an apparently bugged update process. Although I gave up on the never-ending process and unchecked all important and optional updates two months ago (which had only been happening for two weeks after a fresh install of Windows 7 64-bit SP1), Windows still shows the "install updates" icon next to the shutdown button in the start menu (a yellow shield icon) and spends a while preparing and installing updates on about a third of the restarts. And in this last one, on a restart, Windows spent too long in the "shutting down" screen and then displayed a blue screen!

Windows now gives me the option to launch Startup Repair on startup. Opting to start Windows normally will get it stuck at the Windows logo.

The Startup Repair initially asks if I wanna go to the System Recovery Options menu or to use a restore point. However, the list of installed OS's is empty, and opting to use a restore point will display the following error: "An internal error occurred. The following information might help you resolve the error: The system cannot find the file specified. (0x80070002)"

As for the more elaborate Recovery Options menu:

Startup Repair quickly says "Startup Repair cannot repair this computer automatically."

System Restore doesn't work because no Windows installation has been specified.

System Image Recovery returns the same error mentioned above (0x80070002).

And finally, in the Command Prompt, I tried to manually fix the boot record by inputting the following commands:
bootrec /fixMBR
bootrec /fixBoot
bootrec /rebuildBCD

The three of them completed successfully. However, the last one displays this message: "Total identified Windows installations: 0"

What? Failure to detect Windows installations contradicts the fact that the Srartup Repair is kicking in in the first place!

Having gotten here, it's almost clear I have already used up all of my options, and none work.

I can't remember my exact specs, but they include a 3.3 GHz Ivy Bridge Core i5 with a GeForce 760 and 16 GB HyperX RAM on some H/Q77 Gigabyte motherboard. No overclocking, but Intel's SSD caching is at work for the system's 500-GB WD Green drive using a 120-GB Samsung SSD.

The disk acceleration mode might have been set to maximized before the problem occurred, which is similar to 0 RAID if I remember correctly and thus has risk. Might this fact complicate matters?

What would you do if you were me? Is there anything that can be done without using a recovery disc? And is one supposed to be able to solve the problem?

Can you enter safe mode with networking? If you can, then maybe you can make sure the corrupted files are not there and then go on the website to re download the update. Then restart. The repair disk is really easy to make. Just get a blank disk at your local store, go on another computer and get the repair files and burn to the disk. Then put it in your problem computer. You can also do it by usb. Or, maybe, you can do it by a network but that is complicated and I can't help you if you are doing it that way because when it comes to networking type of stuff, I am not very good.

Safemode has changed things, but not necessarily to the better! I pressed F8 on startup and chose to boot in safemode with networking as you told me. However, the computer froze again during the file loading process. I didn't take note of the filename the loading froze at, but the freeze wasn't just a stop in loading, but an obvious crash; a bunch of blue dots showed up on the left side of the upper edge of the screen, like a graphics glitch if you know what I'm talking about. I figured hard resetting was the only solution.

What happens now is that the startup repair is suddenly able to access and interact with my Windows installation! It first asks me to login, then presents me with the recovery options menu, two of which now seem to be functional. The automatic fix attempts a system restore, while the manual usage of system restore shows that there's only one available system restore point, created approximately 22 hours before the blue screen that caused everything. The system restore point's description highlights the install of MagicISO (which I'm guessing is MagicDisc's name in the program files?). Making a manual restore succeeds.

However, regardless of whether I use the manual one or the auto fix, the result is pretty much the same. Upon restarting, the Windows logo shows for about one and a half seconds then a blue screen flashes for a couple milliseconds and the computer restarts into System Recovery.

I gusss this concludes getting stuck again. Got any suggestions before attempting to get my recovery disc?

EDIT: PROBLEM GOT SOLVED.

I forgot to mention that the restart after the safe mode crash first concluded a corruption in the BIOS and started recovering it from a backup, after which my SSD caching setup in the BIOS was reset. For some reason, the presence of SSD caching was preventing the Windows recovery tools from detecting my install, which is the reason why I managed to successfully make a system restore after the SSD caching was disabled. However, at that point startup would fail due to the fact that some of the files were still at the SSD, so what I did was going to the BIOS, enabling SSD caching, then removing the acceleration from the system's disk. That got it booting again.
