Hello all,

It's a long story, but in short

I installed Windows on my mac. Went onto Windows, installed the drivers, but I couldn't see my Mac OS X partition, so I went to disk utility, gave it a drive letter, and all the Mac files were gone -__-

When restarting Mac it still thinks Mac OS is there (you know the option key, which gives you boot drives).

I put the Mac OS X disk in, and well it became 'corrupt' but I have an ISO of the disk, so was wondering if there's a way to boot from an External HDD and install Mac OS X that way.

The OS is snow leopard

Please try and help
QUOTE Thanks

You need to partition the drive (one partition will do) but you have to make sure the drive has a GUID partition map (it's in the partition options) to make the drive bootable
