My new MBP came with Lion already installed. Im not crazy about it and i want to do a fresh install of Snow leopard. Can i use the disk that came with my 2010 MBP?
 
Try it.

Probably not, though. They are coded to each machine type, and a new MBP requires at least 10.6.6.
 
As per apple you can not instal earlier OS than the one that came with your computer. So if your Mac came with Lion you can not install Snow Leopard

Snow leopard will install on the 2011 MBP's, they came with it at first.

He has a 2011 MBP, they came with snow leopard installed when they came out, therefore, a recovery SL Disk from a 2011MBP will work, regardless of if Lion came pre-installed or not. A retail version will not work as the build is too early.

The OP can install SL, and it will work, he just has to locate/buy the correct DVDs.

are we reading the same question? he said it came with Lion installed and therefore my response is correct.
 
Thanks. I have 13 days to decide if i am going to keep my MBP. I will work with Lion and play with the settings till i feel comfortable with it.

Yes, in fact, that is the only windows version supported by the current generation of MBP.

You are incorrect. It is very easy to install Snow Leopard on such a machine; boot the Snow Leopard Restore DVD that came with the MacBook Pro 8,x, format the hard drive using Disk Utility, and install Snow Leopard.

The issue for the OP is to get a hold of the proper Restore DVD.

Ok well then i apoligize snaky69. from my past experience it wouldn't work
 
I talked to Apple support about this yesterday... what they told me was that IF a 2011 MBP came with Lion PRE-INSTALLED, you CANNOT use a snow leopard disk (either retail or a 2011 recovery disk) to wipe the drive and re-install snow leopard.

I asked WHY

He says because of a firmware that has been installed in the machines that ship with Lion.

This is what was told to me by tech support at Apple
