How to get back the memory that I allocated for Linux?

Question

Hard disks

Background
There is a 256GB ssd drive one on the PC. I allocated about 50GB from this and gave it to Linux. Now I have a choice of linux / windows at boot.
Question
How to remove Linux from the PC now, and return the memory to the disk (I have one C drive, and that's it).

Answer 1

Now you first of all launch the GRUP operating system loader. In it, you choose the OS to boot. What can be done:
1. With a special program, such as Acronis, delete the Linux partition, expand the Windows partition, then boot from the Windows installation disk and restore the bootloader.
2. Delete the partition, expand, after that it will boot from the liveCD (installation disk) linux and change the grub settings so that there is one entry in its menu and it is loaded by default, without choosing a system and delaying.
I find it difficult to say which option will be correct, most likely, the first one is easier, because. everything will be done automatically.
An important detail: there will be other small partitions on the disk, if you do not know what they are for, then it is better not to touch them. Well, or figure out what they are for and remove unnecessary ones.
