Generally, it’s as simple as just deleting the Windows NTFS partition. I would leave the others for now. Depending on how you installed your distro they may be related to your Linux installation. Deleting them could prevent you from booting into your Linux installation.
I’m not as familiar with UEFI as BIOS, but I believe UEFI uses a FAT formatted partition for booting into the OS proper.
You may need to adjust the boot order in your UEFI/BIOS afterwards to get it to boot back to Linux afterwards, but that is fairly uncommon in my experience.
The most likely issue you might run into is accidentally wiping your active Linux partition instead of the Windows one.
I would make backups and have your distros install disk handy before you wipe the partitions.
Afterwards, you can resize your linux root to include the now free space or move your home directory to the new partition after formatting it. Your call.




I’ve been with NameCheap for over a decade. They’re a relatively quiet company that’s been around a while.
They’ve never done anything to make me want to change providers. Have my email through them as well. Good uptime. Ok-ish prices. Good customer service the one time I’ve needed it. Web site takes some getting used to, but it’s also never changed since I started using them.
