My system is a 2011 macbook pro with Lion. I installed BC with Win 7, it worked flawlessly.
I install rEFIt and I get all sort of problems. Half of the times I can't boot into Lion, and when I can it takes for ever. Never tried booting into Windows.
I manage to uninstall rEFIt via terminal, because I couldn't delete the refitblessed folder in StartupItems.
I choose the Liion disk in the Starup Disk preference pane. Now Lion boots almost normally.
Finally I try to boot into windows and the partition doesn't show when booting with the alt key pressed. When I chose the BC partition from the Startup Disk pref. pane and restart the computer all I get is a black screen and Windows never starts.
So what now?

Maybe there's something wrong with your partitions or boot code in the MBR.
Use the script at http://members.shaw.ca/joevt/dumpvols2.sh.zip to dump all that information to a text file:
sudo ./dumpvols.sh > dumpvols_result.txt 2>&1
Can you see the Windows partition in the Mac OS X Finder? Does it have the boot files "bootmgr", "Boot" folder, "Boot\BCD". They might be invisible so you might need to enable viewing invisible files in the Finder or use the Terminal.

There was nothing wrong with that partition until I installed rEFIt.
I really needed to use Windows again so I had to reinstall it.
Other issues I'm having after installing rEFIt are being unable to log in into Lion with my user (only with auto login), and weird behaviors of admin authentication when trying to change system preferences.
Never had those problems before, and they all started after installing rEFIt.
You shouldn't use your users as guinea pigs with such a dangerous software. Of course you can, but you shouldn't.
