i used the installer from the desktop. after installation i rebootet and the system hangs after the boot of usb (i think so). after them i bootet again the dvd and maked a manuall installation (i used backtrack4-guide-tutorial.pdf). it worked fine. only, that i can only use it as root. at boot i see that at this point where the system before hangs the filesystem will be booted (i think so . i tested the installation with ext3 and reiserfs.

more infos: i installed bt4 as second OS. the first one is a ubuntu with grub as loader. when i do the bt install i dont install the bootmanager/mbr. i use the grub from ubuntu. can the problem be there?

have u any ideas?

thanx a lot
