Install Snow Leopard From External Disk Drive?

Hello to all you lovely people, I've been a long time lurker on these forums and you've helped me out numerous times when my computers decided to stop working.

I got my Snow Leopard disk in the post today but unfortunately my disk drive in my Macbook Pro seems to finally be well and truly knackered.

I should be able to borrow a usb/firewire disk drive from a friend, so would I be able to install ok from this external drive, and is there anything I would need to mess around with to make it work?

Sorry if this has been answered a thousand times before, or doesn't even seem like it needs answering to most people, but after the hell my macbooks been causing me today (especially with forgetting how to eject the dvd once ive inserted it) and trawling to unsuccessfully find an answer, any help or sound advice would be much appreciated.

Thanks,
Jack

 

Thanks for the link, seems like it will help down the line of things

Just need to try and work out how to get my macbook to read the disk in the first place (it does it 1/100 times so might have to be sheer persistance, or find an already ripped copy from certain shady places.
