[kubuntu] Kubuntu partition has not id letter

view story

http://ubuntuforums.org – Hello there, I installed Kubuntu 12.04 from ISO DVD and it was installed on a partition without ID letter "like C,D..." and was showing many options on reboot but Windows 7 was the last in the list. I tried to fix the issue using Easy BCD software which activated Windows 7 boot as default and Kubuntu exasperated from the boot option. I checked my drives with several Partition programs and found Kubuntu still there. None of those programs was able to grant a letter to the partition and still I cannot launch the Kubuntu. is there any way to fix this issue or I need to wipe the (Hardware)
