Windows 10: How to convert primary partitions to logical partition

I have four primary partitions (System, C: , D: , E: ) and some free space in my Win10 laptop. Now, I want to make create an extended partition which will hold C, D & E as logical partition. How can I do it without loosing data (i don't have a spare hard disk where I can backup the data).

unable to change unallocated space to primary partition or logical partition.

1) Are you able to view the unallocated 100 Gb memory space in the Disk management?

Yes, checked that before posting.

2) How exactly you are trying to change the unallocated space to primary or logical drive?

Open EaseUS Partition Master, highlight the unallocated partition. If it is a primary partition click on "Convert to logical" and if it is a logical partition click on "Convert to primary". Then click apply.

What about the question as to why, when I booted from the W10 ISO disk I was not given the option of where to install the OS? Thanks.

 

Hard disk partitioning

As suspected you have four Primary partitions on the Windows drive, so if you want to add another convert the D Data partition to Logical and then you can add as many as you want:

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

 

MiniTool Partition Wizard free has an option to set a partition as logical. Not sure how it would work. I would delete that HP_TOOLS partition. I've never used mine. But if you want to keep it, you can use MiniTool Partition Wizard free to move the HP_TOOLS partition to the end of the drive, and that would put the unallocated space next to D: drive where it could be added to D: drive - or D: Drive could then be moved over and the free space added to C: Drive.

Just curious - if you don't want to actually create a new partition, why do you want to convert your current partitions to logical?

I want to install Ubuntu in the free space. Ubuntu doesn't support more than 4 primary partitions. I want to keep HP_Tools partitions as well.

 

You could also try the Ubuntu live version and see if it has tools to convert primary partitions to logical, if Partition Wizard doesn't do it. I would definitely move the HP_TOOLS partition to the end first to get it out of the way, though.

 

I did it using MiniTool Partition Wizard. Thanks

 

I agree about using Minitool Partition Wizard. You should be able to convert all of the partitions to Logical. I've done the reverse before, converted Logical to Primary so I don't see why you could not do the opposite.

Yes, right click on the partition in PW and choose "Modify->Set Partition to Logical" - Do it to all of the partitions and then hit "Apply"

 

Ah, already done? great!
