Grub Config file
Actually I am learning about the grub config.
I restarted my system and pressed ESC and got the grub menu which is having 3 lines as
like this.....my question is
If I make changes to the 1st line it is not allowing to boot the system and if I make any changes in the next 2 lines...it is booting and changes are not saved also.....why this is happening????
