I have a Toshiba Satellite L670 that has Win 10 (recent upgrade from Win 7).
When it tries to boot normally - It gets to the windows flag splash screen, and then screen dims and stays there.
When I've selected safe mode - it does the same as above
When safe mode & command prompt - it does the same.
Thus cannot use tools such as sfc and chkdsk.
There are 2 RAM sticks (1 x 2GB, 1 x 1GB) and have temporarily removed the 2GB leaving just 1GB in it for troubleshooting.
I've tried using a linux live cd (ubuntu 14.04) but it could not mount the 2 partitions on the HDD (1 called "Data", another called "Windows").
I do not have a Win 10 disk to hand, but could make one if needed.
Seeking advice please.
1) Went into "Repair your computer", and accessed recovery options > command prompt from there.
2) Intially chkdsk didn't work, however entering the following command, then pressing enter got it working:
chkdsk C: /f /r /x
