Computer wont come out of safemode

Hi my computer seems to be stuck in a endless loop of rebooting itself into safemode then shutting down before i can change anything.
so far i have attempted to use
repair your computer
last known good config
and every other safemode
i am currently trying to use command prompt to disable safemode using this. but instead of (current) it would be default
For example: If I wanted to have Windows 7 not boot into Safe Mode anymore, I would type this command below and press Enter.

bcdedit /deletevalue {current} safeboot

it keeps sayng this is not a command prompt tho.
