From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hey guys, I've been using Linux Mint and Windows 11 via a dual boot setup on two laptops for a while.

I hardly ever use Windows 11, except on my work laptop, so I want to delete it from my personal laptop.

How can I do this? What is the safest and easiest way, and what should I bear in mind?

Thank you in advance for your answers, and have a sunny day!

Step 1: make a backup / clone the disk

Step 2: double check the backup

Step 3: Assuming you've got a grub bootloader, boot into Linux Mint, use GParted or Gnome-Disk-Utility

Step 4: Identify your NTFS Windows 11 partition, the utility should show if it is mounted or not (it should not be mounted unless you added it to /etc/fstab

Step 5: resize your Linux mint partition (ext4fs), & make sure you don't accidentally move the partition

Step 6: sudo update-grub to remove the entries for Windows 11 since it doesn't exist anymore

More info on if you've got an HDD vs SSD, MBR vs GPT partitioning, or a screenshot of your partition table from either of the disk utilities in step 3 would help us help you

This misses the step where you delete the windows partition - between steps 4 and 5. You have to delete the NTFS partition and resize your linux partition to fill the empty space.

You can also create a new linux partition if you wanted as a separate space to store stuff.

Good spot & thank you for the correction!
