today i tried to install win7 from an external hdd to my system. i tried this tut http://www.pcworld.com/article/165159/install_windows_7_from_an_external_hard_drive.html and everything went fine till i pluged off the external hdd. after i pluged it off and tried to restart the system i get a missing boot manager error. if i plug the external hdd in again it's all working fine again.
i've searched for the last 2h and didn't find a good answer. did any of you have one ?
ps: i already tried any forms of reperation and the system is installed on the correct hdd.
