Upgrade MBP to Snow Leopord with external USB HD?

I've been told it's not possible to use a USB drive to boot from and I've read that it can be done on a few different websites. I have the .dmg Snow Leopard file on the external USB HD and want to upgrade my MBP. Can I do this and if so, what do I need to do first to prepare for it (partitioning and such). I've never done anything like this so speak to me like a child!

Where did the DMG of Snow Leopard come from?

Pulled from the DVD using another computer. My DVD drive is not working on my MBP and I was hoping to find a way to upgrade without it. Every time I try to put a DVD in, it sounds like it is trying to read it but eventually just spits it out over and over. What does that have to do with being able to use it from the hard drive? Does it need to be pulled from the DVD in a certain way?

Why did you ask me a question if you weren't going to respond or help?

Gotta love mods.

Mods have lives also. I asked a question to get it started and knew someone else would answer based on your answer which they did.

Google could have helped you on this one. It's good search before posting.

Install OS X Snow Leopard from a USB flash drive

Looks like Crimson beat me to it.

Just to be sure, this is an Intel Mac correct? It's older G4 Macs that will not boot from USB. Never tried a USB boot on my Intel Mac but I read about it all the time.

And another reason for asking is Snow Leopard only will install on an Intel Mac.

Is it sad that I can boot from my iPod if my machine ever did crash? >_>"

If you're going to basically accuse me of illegally downloading the copy of Snow Leopard, the least you could do is wait the two minutes it took for me to respond to your "question"..

Anyway, I did find something that broke it down step by step for me and have updated now. Thanks for the helps folks.

I don't think he accused you of anything. He just asked a question. There is no need to get upset when he was just trying to help.

It was a general question. We DO get a lot of people here who never read the rules and do ask about pirating OSX though.

Glad you got it working.

You know how people like to jump to conclusions and make things darker or dirtier than it needs to be. >_>"

I thought that was a good question, I don't think people would normally use a .dmg of an operating system, more like an install disk.

That's an unfair response. Think about it from someone else's perspective - does it really look legit if someone is looking to use an image to install OS X considering there is no legal distribution method that includes downloading an image?

And no one accused you of illegally pirating OS X. At no point did dtravis7 nor anyone else actually accuse you of pirating OS X. Asking you where you got the image from was a legitimate technical question. If it was a legal copy, there is much to consider. For instance, OS X isn't traditionally installed this way and much can go wrong during image creation.

Perhaps you should take a step back next time and think about how your post will be received before becoming defensive at the slightest bit of resistance (which wasn't all that resistive anyway). Also, again in defence of dtravis7, questions are asked as a means of eliciting more information because you forgot to provide enough in the first place. Would you want a doctor to prescribe you drugs right away without asking you some questions to clarify your condition/illness? Questions are part of the process of providing answers and solutions.
