Mac has new HDD, It won't recognize flash drive to boot.
Hey guys, first time asking a question. I've looked everywhere couldn't find my answer. So I have this mac that I got for real good deal. It obviously hard HDD problems because the owner said the batteries blew up. Everything was really slow with the old HDD. So I replaced the hard drive with 320 gb HDD that has been laying around. I did all the necessary work to make a bootable flash drive because I have another mac.
Then It does recognize the flash, after I click the bootable flash drive it shows this no go sign. Looks like a circle with diagonal cross, and after couple seconds it shuts off. I tried to boot it from DVD but it doesn't show at all. I tried to hit "c" and "option" button. but no help. Please give me a solution. I really want this bad boy to work!
Is this a good question?
