What partition table should I use Ubuntu?
For a Linux-only system, either use MBR or GPT will work fine. MBR is more common, but GPT has some advantages, including support for larger disks. The main issue with GPT is compatibility; not all OSes support it, and some can’t boot from GPT on BIOS-based computers. For just a Linux system, I’d choose GPT.
What partition table does Windows use?
Partition Style: MBR versus GPT By default, the Windows operating system uses the master boot record (MBR) partition style to organize partitions on a disk. Initially, only the 64-bit version of Windows was able to use the new globally unique identifier (GUID) partition table (GPT) partition style.
What partition table type should I use?
As a general rule, each disk device should contain only one partition table. Recent Windows versions, such as Windows 7, can use either a GPT or an MSDOS partition table. Older Windows versions, such as Windows XP, require an MSDOS partition table. GNU/Linux can use either a GPT or an MSDOS partition table.

What happens to blkid UUIDs when you re partition a drive?
So, if re-partition a given drive, all the blkid UUIDs for that drive will change. Part of the reason UUIDs are used as identifiers of partitions and drives is to maintain identifiers even when drives are added or mounted in a different order.
How to tell the difference between UUID and partuuid?
You can get a few hints about the difference between UUID and PARTUUID by specifying the -p option. or whatever device/partition you are looking at. You may have noticed that if there are multiple partitions on the same UUID device, the PARTUUID is mostly the same with the partition number appended.
Is there a way to change the partuuid of a partition?
You can change the PARTUUID of a partition with gdisk. I’d recommend to read man gdisk first. In the following example I show how I changed the PARTUUID of the second partition on my first drive (sda):
How does the partuuid of a disk work?
For disks with msdos-partition-table blkid produces a PARTUUID based on the Disk Signature (Disk identifier) and the partition number ( Source ). Different disks must always have different identifiers.
