format HD and reinstall OSX???

hi

at the moment i cant get into mac osx. when i start my macbook i only get to the light-grey background with the the dark-gray apple logo.

the things is that i have a backup. so i dont need to save data anymore.

now i would like to install the os again. but when i put in my osx cd, the installer programm doesnt start. installed in leopard, but i only got install CDs for tiger.

is there a manuel was to format the HD and reinstall osx?

greetings

restart with the cd/dvd inside the slot and hold down the c button and it will start off the CD.

Then double click on install and do an erase and install and you are good to go. You may wish to do a disk verification prior to the install and certainly a permissions repair after the install.

You need to shut the mac down with the install CD in (you may have to disconnect the power supply and remove the battery if it will not shut down

Connect everything up and restart with the dvd in and keep the C key pressed until the installer starts.

FRom there you can access disk utility from the menu and do a clean format
