There are several ways to check whether a disk uses MBR or GPT partitioning scheme in Linux as well.
The command line method should work on all Linux distributions.
sudo parted -l
[root@vps01 ~]# sudo parted -l
Disk /dev/ploop31780: 42.9GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 42.9GB 42.9GB ext4
For MBR, it would show msdos.
[root@centos7 ~]# sudo parted -l
Disk /dev/sda: 64.4GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 1075MB 1074MB primary xfs boot
2 1075MB 64.4GB 63.3GB primary lvm
