I've got a 100gb bootcamp partition with Windows 7 64-bit installed. I recently upgraded my 2010 iMac to a 2012 iMac. Specs: 27" Core i5, 768gb SSD. I was using rEFIt on the old one just fine. rEFIt is installed on the Macintosh HD, not EFI.  On the new machine, it takes upwards of 2 minutes for the refit menu to appear.  First I tried a repair permissions on the Mac HD.  Then I did some googling and read about "blessing" the partition that refit was installed.  I tried that, but now the refit menu doesn't come up at all.  It does the same ~2 minute pause and then automatically boots to Windows or OS X (depending on which one I choose in the bootcamp manager before rebooting).

If I do a diskutil list in terminal, I get the following:

/dev/disk0
0: GUID_partition_scheme   751.3 GB
1: EFI    209.7 MB
2: Apple_HFS Macintosh HD   649.0 GB
3: Apple_Boot Recovery HD    650.0 MB
4: Microsoft Basic Data BOOTCAMP 101.4 GB

I have a feeling that something USB is causing the slowdown, but I need to at least get rEFIt back to working status before I test that theory.  Does anyone have suggestions?  Thanks!
