|You ONLY need to do a Start Up Repair on your installation. You can do this from an installation disk, a recovery disk set, or a Windows 7 Repair Disk. The Installation disk you do not have, the recovery disk set you could purchase from the manufacturer of your computer, BUT the Repair Disk you should have made when the machine was new. If you did not make the repair disk you can still make it from another Windows 7 machine as long as BOTH are either 32bit or 64bit versions.|
I am not sure it the Recovery console referred to in reply #1 has the capability of doing the Start Up Repair, though it might (see your manual to be sure). You not NOT want to do the Factory Restore unless you have a back up of your personal files or you will lose them. This should be a last resort and only after you have taken steps to make a copy of these files. You can use a CD or DVD with a copy of Puppy Linux or other Live Linux on it to boot to and make a copy of any files you need if it comes to that.
If you are that short on space, add a second hard drive (larger) and move your personal files to the new hard drive so that Windows can work better with a little bit of 'elbow room'.
You have to be a little bit crazy to keep you from going insane.
