I have written before about Windows Startup Repair fixing my computers automagically, but it didn’t work this time.
I am trying to get an old trackball to work properly with new Windows and it was not acting right. I tried to install a driver manually and picked the exactly-wrong one by chance. Blue screen. Reboot, black screen, auto-reboot. Select Safe Mode to avoid loading that driver and . . . black screen in Safe Mode also, auto-reboot.
Startup repair found nothing. I went to run a System Restore and it had NO restore points!* Finally I was able to get back into Windows using the F8 run Last Known Good configuration option. If this had not worked, I hate to think what would have happened. And it’s built in to Windows for more than the last decade. Thanks God and thanks Microsoft.
*I know, I was shocked, too. So first thing first, I set a restore point and then figured out the hard way that the automatic backup I had intended to implement never got done. Also my hard drive is almost full, but I never got any warnings because I have no page file. Oh well. Hard drives are cheap and it looks like a perfect time for a newer one!
