    I had a perfectly working Lion desktop (GA-Z68MA...) that I just used UniBeast to upgrade to Mountain Lion. I was using a single SSD for this install that had dual-boot with Lion and NTFS Win7. So I'm thinking this might be the issue with the ML install corrupting the boot record or something. So basically I could select Lion in Chimera previously, but now that I've installed Mountain Lion when I go to the Chimera bootloader screen I can't even see the Mountain Lion partition to select. I can boot into other backup partitions to run Lion and confirm the drive is visible, etc. I just can't select it in the bootloader. Thoughts?
