How to re-enable Microsoft OS at startup?

[dturner0528]

Ok, first up, I want to say that I know I'm an idiot, and that I should have been paying closer attention, so please; useful comments only.

Alright. So I have a remote link to my personal computer from my work computer because I have been converting a lot of recorded TV for my wife.
While remoting in, I started cleaning some stuff up, because it had been a while since I had done so (almost 80 gbs in the recycle bin, and around 30 gbs in temp files). I went to the startup tab in MSCONFIG and started checking through, and there was a bunch of useless crap that started automatically. I 'disabled all' with the FULL INTENTION of re-selecting the OS so the computer could actually boot.
However, I got distracted with something at work, and when I came back, I simply clicked OK instead of making sure that I re-enabled it. Of course, though, I managed to reselect my remote control software, but not the OS. Of course now, after the automatic restart, I cannot log in anymore.
Now, I'm not home to see what the computer is now doing, but I want to know if anyone has any advise concerning this problem before I go face it and spend potential hours fighting it. I DO have the original install DVD so I'm assuming i would need to run the startup repair off of it or something to that effect.
I can reinstall the OS (which is windows 7 professional, by the way) if I need to, but i'd prefer not to if at all possible. I have plenty of Linux disks to back up my files.
Thanks for any help.

Hi boot from the dvd and run system restore Put the disc in your optical drive and restart to boot from the DVD. You may have to change the boot settings in your BIOS if booting from a CD/DVD is not enabled. Watch for the “Press any key to boot from CD or DVD” message.
On the "Install Windows" screen, make the appropriate selections for language, time, and keyboard, and then click “Next”.
On the next screen, click “Repair Your Computer”. Do not click "Install now"
In “System Recovery Options”, select which operating system you want to restore if any are listed. It will be blank in many systems with only one operating system.
Click “Next”.
The “System Recovery Options” screen will open.
Select “System restore” or Startup repair or whichever option you wish to apply.
