actually its dosnt even make it to Grub, its the EMI menu on Intel servers... so I guess it cannot even find a proper boot device.. ill have to do more research on the issue. if you have any ideas why that would also be great help. thanks alot, Quoting Aleksandar Milivojevic <alex at milivojevic.org>: > Quoting Nathan <lists at netdigix.com>: > > > no its the prompt centos goes to when it cannot find anything to boot to. > > So it's the grub prompt most likely.
