Fedora 16 64-bit on Dell xps 15z returns "operating system not found" on reboot
I am trying to install fedora 16 64-bit netinst on a new dell xps 15z. I use the pci=noacpi kernel param during install to get it to install, but when, after install completes, it performs a reboot, I get the message "Operating system not found". I've found a few links that say it is probably a bad disk but I don't think so as it installs perfecrtly well, and it worked with the pre-installed windows 7.
I notice that fedora 16 by default uses the ext4 file system, and the boot bios partition. Could this be an issue. I'm stuck so any help would be appreciated.
