hello, i have a macbook pro 17" 2007 (3,1) and removed the superdrive to install a sata pata hdd adapter (and a hdd obviously) and had no problems so far, everything worked perfectly (without windows, osx only). i tried to install win7 via bootcamp, couldn't boot from install dvd with two different external usb dvd drives(only showing efi boot, black screen), opened the macbook, took the 2nd hdd adapter out, superdrive in again and the dvd bootet just fine installed windows, worked perfectly for a day, but stopped as soon as i put the 2nd hdd back in. suddenly i have the choice between two "Windows" labeled symbols when holding alt (in diskutil there's just osx, win and the 200mb part) and both of them just show me "missing operating system" if selected. osx works and windows works if i remove the second hdd, but I'd really like to keep it... i tried to install refit, no change, tried to fdisk -e /dev/rdisk0 (main hdd) and f 2 (osx part) but the partition was active already so obviously no change as well.. if I flag the windows part I get the same "missing operating system" error. strange: if i boot from osx install-stick and open the "startup disk" utility i can select either OSX HD or BOOTCAMP, the "startup disk" utility of the booted OSX (OS) only shows me the OSX HD. Same result as flagging the Bootcamp part, though. any ideas?
