Windows 10, how to make a partition primary?

Question

Windows

There are two partitions on the hard drive, one is primary, the other is logical, respectively. Both have windows 10x64, when you turn it on, you can choose which one to download. You need to leave one section, the one that is now logical. The one that is now primary, you just need to erase and attach to the second. There is a program EaseUS Partition Master 10.8, with its help I change the size of partitions. There is a Windows installation disk, but I don’t want to install it again, in order to save time. How to solve the problem without crashing the information on the disk?

Answer 1

There are two partitions on the hard drive, one is primary, the other is logical, respectively.

Sections (partition) are basic (primary) and additional (extended).
But they are not exactly logical. A logical volume can be a volume, but not a partition.
Based on the foregoing, I can assume that you have two sections - the main one, and the additional one.
The main one is active - it contains the OS boot record.
If you delete it, you will no longer be able to boot from this disk, and, of course, all the information it contains.
You will either have to restore the boot record (this is real if you have experience and skills) or reinstall the system.

Answer 2

I have never used the EaseUS Partition Master program, and I would venture to offer a Paragon HDM to solve your problem, which you can use for free using one of the countless LiveCD/DVD/USB recovery tools. It can convert partitions from logical to primary, from GPT to MBR and vice versa, make them active (i.e. bootable) and vice versa (without losing information on partitions), merge / split partitions and much more.
