Maybe the quickest way to find out is to install manually via PXE. Use the same disk structure etc. you use in the kickstart, stay as close as possible. If that succeeds compare the kickstart log for that install with your kickstart file. It's possible that you have some directive in there that wasn't 100% correct, but failed gracefully before and now it doesn't. I assume you have already watched one of the failing kickstart installs to rule out any missing files or other glitches that would be visible on the install screen that runs thru? I also assume that you at least verified that the partitions are there and filled with reasonably looking files. > my /etc/grub.conf looks fine it doesn't contain the boot config. Kai
