My system restarts after completing the basic installation (update from 11SP1 to 11SP2), however it failed to boot up to complete the automatic configuration. The grub menu display fine and when trying to boot into 11SP2, it displays the system specification(i.e. filesystem type, partition type, etc) and hang after displaying: initrd /boot/initrd-3.0.12-0.27-default
[Linux-initrd@0x378f3000, 0x6fc94b bytes].
I have tried repairing the system and updating my system again but I am still unable to boot up. I'm really not sure where the problem is and how to resolve. I do not wish to do a fresh installation as it would wipe out all previous stored data.
