dual boot problem(2 centos) - beep 6 times or more
 

i was booting only one os which is centos. but when i turn on my laptop this morning theres already two centos in my system and it beeps more than 6 to 8 times

This rather looks like hardware error. Start with checking RAM and harddisk. For instructions look here: http://www.linuxquestions.org/questi...re-4175461588/

solved, i just delete another centos config in /boot file. and boom it runs normally
