hey everyone i picked up a old 2007 imac from work and it works great, however before i could take it i needed to erase everything off the hdd and since i didnt have my snow leopard dvd with me i had to install windows 7 32 bit, well now i have it home and want to install SL so i can install 10.7 but i cannot get it to boot from the dvd when i try to go to the boot menu it just spits out the disc, is there anyway for me to reinstall os x?
