Hello guys this is my first day here... Im having this stupid unpurpose problem with my iMac. So this is the story I got a Vista in my iMac with Boot Camp running it was perfect but when one day i thought of upgrading to a higher HDD size to install more games... SO i boot with my Macintosh and partitioned it into one HDD then i try to partitioned it again into two but it seems to have a problem like this * i kinda forget... it says like it cannot be partitioned,* then i erased my Mac HDD by booting up the Mac O SX disc then utility then Disc Utility then Erased ,,, after it i quit... then restart my Mac. Oh damn the Leopard's gone what should i do now?? i tried installing back Leopard but it seems not to work it says Leopard Cannot Be Installed In This Computer then tried installing Vista but it says it needs the HDD to be not a specific format.. so now can someone help ??
