I could not enter in safe mode, though I stroke F8 during POST screen before windows 7 booting start. Anyone have any idea what might be cause and how to resolve it. I have checked system file with SFC in windows mode. I use win7pro in intel i5, 4Gb RAM, 500 Gb HD laptop.
If I time it just right, a single tap of F8 will do, but that's rare. What I do is begin tapping F8 as soon as reboot starts (rapid tapping; maybe two taps/second) until I enter Safe Mode. If you fill the keyboard buffer (I think KB buffer) you'll get clicks back for your computer. I sometimes stop tapping at that point, sometimes I don't.
Ah yes ... the "Final Option" generally solves a whole multitude of problems. Glad you got it working.
