Stuck at SAFE MODE, does not accept password

[REDACTED]

Are you typing the following in the command box :

G:\FRST64.exe

Yes but it doesn't seem to accept any of my " :\ " commands, is there any other command to use that means the same?

Edit:
I figured out i need to write " :\> " for it to be valid but I got "access is denied"

Edit 2: Must have been about using cmd as user and not admin. Sorry I will try this step one more time.

Did it work with you being the Administrator?

I fixed it! Me and nobody else found the problem! (just joking ofc)

It was the noob (me) sitting in my chair punching in a 4 digit number to log in when windows 8 ran in SAFE MODE wanted me to punch in the Microsoft account password and NOT the 4 digit pin code I had made.

So I have learned a lot about how to fix many kinds of problems that I didn't have and use the Command prompt and been guided professionally here on Avast and I thank you all for that.

Unfortunately I figured it out after unplugging the System Disk and installing Windows 8 on my second disk there by losing around 500gb of data. So when the new install asked me to make a Microsoft account using my email and password, it slowly dawned on me (very slowly) that maybe just maybe this was the password I should have used with SAFE MODE 

When next I plugged the "problem" disk back on and used the Microsoft account password I got in with no problems and there was Avast Uninstall program waiting for me to finish installing it. Since I never needed it in the first place I discontinued the AvastClean install.

Well once more thanks a lot for you guys time and efforts in helping me and I am so sorry to have been a fool. Of course I could blame it on the heat, yes I will do that

Similar to using an extension cord that's plugged into a dead socket and wondering why the lamp doesn't light.
Even replacing the light bulb didn't work.
Glad to hear you problem is finally solved.
You should now have gained enough knowledge to help some other less knowledgeable folks.
