I have 2 OS installed on the disk: Windows 10 and Linux Ubuntu (I met her and got bored ). How do I now remove Ubuntu so that Windows continues to run and boot (I don’t want to completely reinstall everything).
Thank you in advance.
In general, this “operation” is simple, but there may be nuances… (especially if you initially had 2 OS at the time of purchase, + hidden partitions for recovery – this sometimes happens on some laptops) .
In this note, I will consider the general case: when you had Windows 10 installed on your disk, and then, in addition, Linux Ubuntu (Mint, etc.). And now you need to delete the last one (without losing all disk information and Windows health).
By using the following tools and recommendations – you can remove all disk information! Although I show all the steps with examples, there can always be “features” – so anything you do – do at your own risk!

Remove Linux: step by step
STEP 1: preparation
To start you must copy all the necessary data from the partitions you want to delete! By the way, you can read disk partitions with Ext2/3/4 directly in Windows.

Secondwhat you need to do is to prepare a flash drive 👉 LiveCD (by Sergey Strelts) (link to instructions to prepare it).
It will allow you to perform all these operations sufficiently easily (it will be possible to delete, among other things, hidden partitions, which it is not always possible to delete under Windows. Moreover, you will not have to use the command line…).
STEP 2: delete unwanted partitions
Now to the point…
We connect the prepared LiveCD flash drive, turn on the PC and open the boot menu – select it from the list and start. If anyone is having trouble with this, the link below will help! 👌

How to boot from USB flash drive or external hard drive – see instructions
When Windows PE is loaded from a LiveCD flash drive, you need to run the utility “Minitool Partition Wizard” (“Hard disk” section).
To note: this utility is good because it allows you to delete all disk partitions (including those of the hidden system).
Now with caution!
If you installed Windows first (which is likely), the first 3 partitions of the disk will be used by it (including the “C:” drive).
But all other partitions (“D:”, “E:”, and others without letters) are used by Linux (you, as a user, probably know best which partitions to delete 👌). Fortunately, Minitool Partition Wizard allows you to delete all partitions… 👇
Once the changes are made, click the button to apply them. “To apply” (at the bottom of the window 👇).
We have now deleted Linux and all files that were on the selected partitions. After that, you need to restore the Windows 👇 bootloader (because you’re most likely using GRUB right now).
STEP 3: Bootloader Recovery
Sergey Strelts’ LiveCD is good because there are promotions on his “board”. the Dism++ utility, which restores the bootloader in 2 clicks. Let’s see how it’s done.
1) Run the utility first Unpleasant++ from the menu START/Utilities.
2) Next, select the copy of the Windows operating system that is installed on the disk (usually it’s the second in the top menu – it has the “C:” drive 👇) and click on the menu “Restore / Restore Boot”.
3) In the menu that appears, it is best to click on the button “Continued”and manually specify a disk with a size of 100-500 MB – usually this is the first in the list (the bootloader will be written there).
4) If everything went well, a window will appear about the success of the operation.
5) You can now restart your computer…

STEP 4: If the GRUB menu appears
If after reboot the GRUB menu appears, as in my screenshot below 👇 (but the bootloader was restored) – you need to 👉 go to BIOS/UEFI and check what is indicated in the menu starting “STARTUP”.
In the first place (boot option #1) – you need to put Windows Boot Manager (Windows Boot Loader) and save settings (F10 key).
After that, Windows starts loading normally… 👌
👉 Besidesif you want to use the “freed up” disk space – you need to run the disk management utility (built into Windows), right-click on the unallocated area and create simple volumes (see example below 👇).
Then click several times “Further away” (along the way, choose a drive letter and file system). 👇
Well, after that you will have a new logical drive – in my case “D:”. Now it can be used like any other disk (the explorer will see it).
