How to delete bootloader partition in windows 10?

Question

Windows

Before installing 10ki, I turned off uefi, converted the disk to mbr, but 10ka anyway transferred the bootloader to a separate volume. As a result, we have a C, D drive and a partition with a bootloader. I'm transferring the bootloader to drive C. I'm trying to delete the partition in which the bootloader was. The section is naturally not deleted. I boot from a USB flash drive and do the following through diskpart.
I first select the desired disk, then select the
select partition 1 partition
, the system writes that the partition is selected and I accordingly write:
delete partition override
As a result, it erases not the partition that I chose, but disk C. Which was partition number 0.
What do I do not so and how to delete this system partition? (I will transfer the bootloader).

Answer 1

I don’t even ask why this is necessary
. You can download ubuntu and get bogged down in lifecd mode. And there is most likely gparted. We launch and bang the excess :-)

Answer 2

Well, in order not to be mistaken, open the disk manager - the disk numbering there coincides with the Diskpart utility.
First, make a list, then sel disk, and then work on the selected disk with partitions.
