My macbook pro won't start up properly - upon switching on, it goes to the light grey loading screen and gets stuck there. Occasionally (but not always) a folder icon with a question mark inside appears.
I googled and the solution seemed to be start in safe mode (command R) - but it won't even do that.
Can anyone help?
Thanks!

Shut down
Disconnect all external devices
Reset the System Management Controller (SMC)

repeat 2/3 times
Reset the nonvolatile random-access memory (NVRAM)

if you cant do this you will need to unlock the firmware password in recovery mode which may become available after disconnecting devices and resetting the SMC.
Then use safeboot (SHIFT at Startup)

Then reboot normally with devices disconnected.
if that fails check the drive with disk recovery
