macbook pro doesnt find any partitions and doesnt boot from usb

post #1 of 4
Thread Starter 

I was playing with the partitions, i used dd command to overwrite one partition to another and i messed up. When my macbook pro starts it doesnt find any partition to boot. Because my dvd drive is broken i created a bootable usb to boot from it. When i boot the computer and  press alt button, the bootable device is regognised regular but when i press enter or click on device icon to boot from it, it doesnt happen anything. Please help me.

Right, first of all which OS are you on? lion or mountain lion? or hell even snow leopard!? if L or ML then at boot-up does it show a Recovery partition? if so click that and go into Disk Utility-Partition tab-and create a new one then after creating it go back to the list of options and choose reinstall, from there I think its pretty self explanatory.

 

If you you could specify what mac and what OS it was it would help!
