Most reasons for GPT being preferable to MBR were covered, but it is worth noting that if you have a disk larger than 2TB (with 512-byte sectors) MBR won't be able to deal with it. GPT would be your only option. For smaller disk sizes MBR has worked fine since 1980, so there should be no immediate reason to replace it. However, for a new installation the more reliable and flexible GPT is IMHO a no brainer. -- Regards, Mick
