Introduction: This manuscript is explicating the mutual compatibility of boot modes in a computer system and partition-ing styles of Hard Disk Drive. Most of us are familiar with these terms and know a little about these. Method: This manuscript contains the ample information about the boot modes of a computer system and partitioning styles of Hard Disk Drive (HDD) and their related configuration through which we get to know about their configuration and endurability. It also contains some practically verified case studies of the problems which occur due to the wrong con-figuration of boot modes and partitioning styles, though there are lot more but the most common ones are discussed along with their solutions. Result: In order to achieve the compatibility, it might require to convert the primary HDD into either GPT or MBR parti-tioning schemes. It should be marked that this interconversion wipes data on HDD, so cautiously the data on the hard drive must be backed-up before any conversion process. Conclusion: The information contained had been practically verified and is helpful in coping with the newer technology trends which contains more features along with backward compatibility. Keywords: Mobile IPv4, Mobile IPv6, NEMO, QoS, NS-2. Discussion: Right now passengers of flight are forced to interact with flight’s pre-recorded entertainment system. Most of the passenger airlines do not allow a passenger to use the internet or any other type of interaction with the ground while during the flight. They force passengers to even switch their mobile to FLIGHT MODE so that there is no active commu-nication between a passenger and the remaining world.
