Grub install error when the installation Finish

Hi! It's me again! I use pungi to create a custom fedora and it runs perfectly even the iso images was created ok! So I burn 2 CD and try to install in a new machine. It runs ok, load and use all the ks.cfg values and the kickstart installation was good. But when the system show the message that are installing the boot manager to the disk it stop and in the console window it shows the following error: executil.py line 81 in execWithRedirect bootloader.py lines 958, 1199 e 190 dispatch.py line 203 text.py line 605 anaconda line 955 Errno - File or directory not found I noticed that it seems that the script are looking for grub in the folder /sbin/grub but it is on the folder /usr/sbin/grub. I don't know if it's the problem, but for this time this is the maximum debug that I can get and show to you ok! Thank's for all!
