That would be DISM very likely. It appears it was interrupted by the check disk prompt. Just to clarify, you get that every time when you try to boot Win8 in any mode?
When I boot into 8.1 ..I always get Repairing PC and then it goes to Advanced repair options. I was only trying to use the Command Prompt in Advanced Setting..I am not sure what you mean..Sorry...Every time I run Command Prompt within Windows 10 and run the SFC I get that message about restarting PC.
Okay, when in Advanced Repair Options in Win 8.1 did you try going to Startup Settings and restarting and then trying all different Safe Mode options to check if any of these work?
No I cannot boot up in safemode in 8.1. Sorry about the confusion. I cannot get any where when rebooting the PC. I have 2 options. Windows 10 or 8.1 and 8.1 always keeps sending me to Repair. With the advanced options.
Great news! I made another disk of 8.1 ISO. Then I started the disk in Windows 10 and 8.1 asked me for a keycode to activate and I entered that . I got an error of course because you cannot downgrade. But I was just seeing if this disk was bootable. I restarted my system and went into 8.1 partition and got the Preparing Auto Repair and I went to Advanced options and clicked Reset this PC. Then it told me to insert Media. Which asked to reset all drives and I said no just this one. So it looks like 8.1N Pro is now my default and I can now boot from both partitions. I am good to go. Thank you so much for all your patience and help & support This is now solved. :dance:
