I call this special because I am unable to boot into safe mode. If I were, I imagine this would be a relatively easy fix through system restore, or simply transfering files off of the PC, changing the update list, then transferring the files back on if I could get safe mode to operate. Alas, not so much. For the sake of information, I'm working on a Toshiba Satellite, s75Dt-A7330, and the failure is on update operation 513 out of 158863. The file that is failing is pku2u.dll. Obviously, we're dealing with Windows 8. And the error occurred when attempting to update to 8.1. This is my mother's PC that I'm dealing with. And honestly, I doubt either of us will mind if we don't update to 8.1. So once the problem is fixed, I could reasonably just disable the update. Anyway, I digress.....
Are there any special little tricks aside from F8 that allow a person to boot into safe mode? I am able, thankfully for some shred of hope, to hit F12 and enter the boot menu. From there, I can go to setup. And from there, I tried to boot from Hiren's Boot CD so that I could transfer the data off of the computer via mini-XP. Joy, oh, joy though, after the priority change to boot from CD, the PC still appears to try and boot directly from the hard drive (or at least it simply returns me to the fatal error screen). At that point, I'd worn out my knowledge and my search for information online turned up mostly forum posts dealing with Windows 7, and none of them mentioned being unable to boot into safe mode.
So, I appreciate the help.
