How do I remove Ubuntu from a Windows drive?

Question

linux

Installed Ubuntu next to Windows, now I need to remove Ubuntu completely without damaging Windows files. Are there any ways to remove it? Grub has long been replaced by the Windows bootloader, and the Ubuntu files are still somewhere in the C drive partition and take up space.

Answer 1

The file system of Linux and Windows are completely different, so it is unlikely that files from one system lie in another.
If they put Linux next to Windows, then they created a separate partition on the hard drive.
Here you need to delete it, and then expand the partition with Windows using the freed space

Answer 2

Ubuntu can still be installed next to Windows:

It was necessary to remove it through the same installer. And now look on the disk for files and folders wubi.*, ubuntu.* - most likely, everything is there.
