This is all happening on my MacBookPro early 2011. Since I need my computer I would like to create a new partition and install the new Mountain Lion OS on it, in order to explore the new functions first before migrating from Snow Leopard to Mountain Lion. Previously I installed Lion in an external HDD and booted from there. It worked but the performance was not as good. Therefore I would like to install it Mountain Lion onto my main HDD. There is not really to much information on how this can be done and in which order or if it is actually possible with the new Mountain Lion. Thank you all in advance for your support.... Have a good day, Thanks... Dear Mac Community,

Couple questions: - I had my user on a FW drive, and plan on doing that again. Anyone done this and shared your user directory from both Lion and Mtn Lion/DP2 in your dual boot? Any gotchas? - In similar fashion, I want to put the Applications in its own volume (main disk is fine), and put an alias to them from both the boot vols. Anyone done it? - Lastly, can one just copy the contents of the recovery volume to a 5G volume on an external disk (FW800, in this, uh, case)? Thanks! Good stuff, just for what I was looking.

For my configuration it's the same issue. I have SL, Lion and ML DP2 installed and everytime when I switch booting between Lion and ML Spotlight does a re-index. Boooo, ... me, did you find a solution for the Spotlight problem?

I have Lion and ML on the same disk now and I see Recovery HD only once on the alt-boot screen. And I also cannot approve what ML installer would have done as I have copied the ML partition of a virtual machine onto a physical disk. So I was left to create the Recovery HD manually. I don't see any difference on the boot screen if I either take Recovery HD or Recovery-10.8 ... I always have one Recovery HD on screen. Does the name of the Recovery partition make a difference to Mountain Lion, i.e. does it rely on it to work properly? AJ, can you say something more about the “Competing Recovery Partitions”?

It is not recommended that you upgrade your running Lion to Mountain Lion. DP1 and DP2 are previews to the new OS and therefore they both have definitively issues. So I would consider such activity as "forbidden". What you can do is to clone your Lion to a second disk. Then rename the volume to anything other that Macintosh HD or Lion (mine is MLion HD btw). After that you can apply an upgrade of DP2 to this new copy. But there is no need to do an upgrade - you can create an empty volume HFS+ on a second disk from Lion, start the ML DP2 installer and CHANGE target location to the new empty volume.

I did this after accidentally over writing Lion; now applied Lion updates and back to 10.7.3 :-) I MAY partition and try ML as a clean install, but before I do can anyone confirm they have done this and not ran into any conflicting partition issues?
