Fedora 16 install: "no operating system found"

edit

I am trying to install Fedora on my dedicated server. Have spent the whole day on it without much success.

First, I am unable to figure out how to configure Raid 1. I have two disks.

Second, even after I had given up and chose that all space should be allocated using the default partition scheme, then after reboot there is just a "no operating system found" message. (Tried this, no change: http://blog.mornati.net/2011/11/30/fedora-16-boot-problem-after-install/).

I have been quite happily using Fedora since Fedora Core 3 on all my servers and laptop but now I am seriously going to install Ubuntu if I don't figure this out which makes me quite sad.

Any hints will be greatly appreciated.
