Even can't open safe mode I tried thousand times.
I have MBP late 2011 13"
The issue now is the active disc that contains OS is full with no single byte free and doesn't mount or load OS to computer run and always a grey bar appears upon starting the PC.
I tried to increase Macintosh HD space by partition but it says you can not change because the disc is locked. When tried to unlock disc from disc utility and than startup disc the PC stands still or hangs up.
I don't have Mac OS disc or any apple shop in me area.
Please help me as soon as possible

Can't modify oration , says disc is locked
