Can one disk drive have mbr partitions followed by GPT partitions ?

for illustration (kind of using mini tool partition) :

Disk 1:

Volume   drive    Partition    Part. style   Status

             letter 

1                            primary      MBR          system active

2           C                primary     MBR          boot

3           D                primary      MBR        none

4           E                 primary     MBR         none

5            J                primary      GPT         none

6            K                 primary     GPT        none

7            L      ...

8            M     ...

9  ...

10 ...

11         X  ..                                GPT  ...

...  so on

 

If yes how to make it such and by using which tool that'd perform best and easiest ?

Short Answer: No. You cannot have one disk having both a GPT and MBR partition table. It has to be one or the other. 

 

It would be clearer if you opened a command prompt and posted the output of the following commands

 

diskpart

list disk

 

In your case if you have a motherboard with a Legacy BIOS your boot disk would be MBR as GPT has difficulty booting from Legacy BIOS computers. GPT is required to boot from computers with UEFI and is also required to access large capacity drives over 2TB. A MBR disk can boot from a UEFI computer if the UEFI settings are set to Legacy or CSM boot.

 

I'm guessing your Volume number 1 is 100MB, the System Reserved Partition. With Volumes 1,C,D,and E possibly being on one disk and J and K being on a large capacity disk or J and K being separate large capacity disks.

 

I would not advise attempting to change from MBR to GPT if the computer boots correctly.
