Hi stoat, thanks for the detailed information. I ended up reinstalling fedora again but still the partition table is not recognised. I ran testdisk and rebooted but still no luck. Here is the log output:

Notice the extended partition in /dev/sda is flagged to boot after installing fedora. I guess that is because the extended partitions of the primary type and the linux partitions are logical volumes.
