hi, can someone please help me. i've been on google for weeks trying to figure this out and i finally got smart and decided to join mac-forums.. but anyways, my macbook (may 07) was dropped a few months ago and i finally got the money to buy a new hard drive. i put the new hard drive in and used my friends install disc to try and install mac osx because mine is nowhere to be found. she has a brand new macbook pro and is running leopard, i was running tiger before my macbook was dropped. my macbook recognizes my hard drive but everytime i try and install it "the underlying task reported failure on exit" pops up. please help!!!!
