After installation reboot I'm stuck on yellow background with feather...

I'm using LL on an ancient 32-bit 'puter with very modest specs.  When that happened to me the first 3 or 4 times I re-started using the power button.  When that didn't work I waited it out - a full 2 or 3 minutes, and it finally booted up.  Your specs are much better and you're using a 64-bit machine so my experience may not be helpful at all, but just say'n... try just waiting a little bit.

I wonder if it's a Grub2 thing... lots of trouble with it on my other computer running PCLinuxOS Xfce, it seems the latest version is buggy.  Just out of curiosity, the installer asks where you want the bootloader installed... hopefully you specified your HDD.
