in my case :
first , with easyBCD i have "chain booting error " (osX and win7 in separate HD)
second, with chameleon and clover boot0: test, boot0:error (osX and win7 in separate HD)
third , with easyBCD i have "missing operating system" (osX and win7 in the same HD, but different partitions), after repair of win 7 i got boot0: test, boot0:error
fourth, with chameleon and clover i have "missing operating system" (osX and win7 in the same HD, but different partitions), after repair of win 7 i got bootmgr is missing when i try to boot osx
NB: when installing osx the chameleon interface don't show when pressing 1 at boot0 , just the clover interface
