I installed Lion fine on my macbook air, but when I try to install it on my iMac it goes to the screen where it says "Preparing for Install" and the progress bar gets a tiny bit into it and then moves back and fourth a pixel or two forever. I left it overnight and it never proceeded.

Tried restarting and turning off Time Machine.

I have a 27" core i7 with a Bootcamp partition of 80gb. Still have lots of space free on the Mac HD.

Any ideas?

I had the same problem. Hit cancel installation but when it prompts you if you are sure you want to quit installation, hit no and continue installation instead. Let me know if anyone else is successful doing this.

Bump: Lion install frozen.

I also posted this issue over in the Macbook sub forum. Hopefully I can get some visibility here as well since I'm not sure if I have a software or hardware issue.

I upgraded the memory and storage in an older MacBook and am now having trouble with the install. It gets hung up / frozen on the "Preparing to install" screen.
Here's what I'm working with:

MacBook 13.2", late 2006.
2.0 GHz Intel Core 2 Duo White
s/n W87070YKWGL.
Model: MA700LL/A

RAM: Crucial 4GB Kit (2GBx2) DDR2 667MHz (PC2-5300) CL5 SODIMM 200-Pin Notebook Memory Modules CT2KIT25664AC667

SSD:Crucial M500 240GB SATA 2.5-Inch 7mm Internal Solid State Drive CT240M500SSD1

The original hard drive has long been dead and I'm basically working from scratch. I purchased OSX Lion online and then, using an 8g thumb drive, created a bootable USB for the install. The new SSD was formatted with a GUID partition using an external enclosure and my iMac.
I tried reformatting the drive and digging around online for solutions, but maybe I'm not using the right search words.
Can someone help me troubleshoot?
Edit: here are a few pics to show what I'm working with:

Other forums suggested the SSD is incompatible. Others cite Lion being the problem and TRIM being unsupported. Seems the SATA is simply limited to SATA1 and not incompatible, Lion has been successfully installed on other MB here, and, as I understand it, TRIM is something I'll deal with after install. This is the most positive thread on the subject of SSDs I've read so far.
