Hi all, this is my first post, I´m sure you can help me with this...
I am booting RHEL 6 with Kickstart and I am getting this eror:

--------------------------------------------------------
"The kickstart configuration file is missing required information that anaconda cannot prompt for. Please add the following sections and try again:

bootloader configuration"
--------------------------------------------------------

But... the bootloader info is already there. This is an excerpt of the kickstart file:

-----------------------------------------------------
auth
bootloader --driveorder=sda

clearpart --drives=sda --initlabel
part /boot --fstype=ext4 --asprimary --size=100
part swap --asprimary --size=2048
.
.
.
------------------------------------------------------

Thank you!!
Juan

I think the --location parameter is always required, e.g. --location=mbr

I have tried it and I get the same message... Thank you anyway.

well show us the entire file please.

OK ! Here it is the one I am checking now...
