I upgraded from Windows 7 to Windows 8 enterprise; before doing so I was using daemon to tools to mount the image of Windows 8. I did not do a clean install as I wanted all my data to transfer over. Everything was going through fine and then on the last step I kept getting the blue screen of death with error KMODE EXCEPTION NOT HANDLED (epfwwfpr.sys). After restarting and seeing if it will work the same thing happens. I then removed all peripheral devices including my wireless network card but only after a few restarts.
After a couple of automatic restarts I get into system recovery options, so I tried a startup repair, no joy. I then tried system restore and to my horror there is no restore points saved. I tried restarting and going into safe mode by pressing the F8 key but it pressing F8 makes no difference. So I got back into system recovery options and went into command prompt and tried the bcdedit method, restarted the computer it again tried to load windows 8 a couple of times and then went into Windows 7 system recovery options started loading drivers as if it was going into safe mode but no, it went back to system recovery options. I cannot access any form of windows to run any tests to see what drivers are causing issues.
I now have no idea what to do and I'm stuck in this constant loop. Please someone help me out.
looks like you are going to have to do a fresh install anyways...
