I don't know if this applies to other computers, but do check.
When I got this computer not long ago. It had Windows 8. I had changed the safe mode startup according to You Tube in command prompt to boot up by using the F8 key and it worked fine.
When I did the free upgrade to Windows 8.1 for 8 users. I thought I better check to see if I can get in safe mode with the F8 key. To my surprise it went back to the Windows 8 method ( maybe by default, iam not sure ) to get into safe mode. I changed it again and it works fine, I did check this out.
