Do I need a previous installation of OS X to install Snow leopard?

We have erased the previous partition to the imac and i got myself the compacted snow leopard whole install disc.I have a very imac TWENTY ONE.5″ 2010 version with the intel i3 500gb hard disk drive.

OS X doesn’t get “full install” compared to.”upgrade” hard disks.You never need a current install of OS X on generally there.

nope no need a current version simply just pop in the disc and from there i have no idea of exact points (because i avoid mac) nonetheless if it truly is anything such as linux it will be pretty simple investment with things you require to accomplish.

No you don’t.Simply boot in the disc and also proceed with the installation.
