- Thank you so much! I added Mint to a Win10 system on 7 year old hardware. The Win10 crawls (likely due to only having 4GB memory) and Mint is fine.
- moral of the video : sudo update-grub
- THANK YOU SO MUCH!!! You made something that was new to me that seemed so hard and complicated actually extremely easy and enjoyable. Thanks for sharing the extra bit about what ifs and whys. Thanks for sharing your knowledge
- Thank you so much for your helpful video. On another note, the timbre of your voice is very much like the voice that Stephen Hawking used but with way better enunciation. I hope you take that as a complement, because I would.

- Hi, Dorian. Great video. Can you provide a legitimate link to GParted? Thanks.
- I've seen that you're disk is a basic disk. Is it possible to dual boot on dynamic disk and on older or legacy bios? If so, how?
- Nice video. I'm planning something similar: KDE neon, Fedora and Windows on one SSD.
For me, formatting will be a little different as I prefer F2FS for my SSDs. (Ext4 is fine for HDDs but it has no special optimizations for SSDs.) Grub doesn't seem to support F2FS very well, so a common practice is to create a separate /boot partition. I think this point is missing in that video. (I read that newer versions of grub might well support F2FS, but when I tried it the last time, it didn't work.)

A separate /boot partition is also used if you plan to encrypt your main partition (the '/' partition) with something like LUKS/cryptsetup.
Many people format that /boot partition with ext2 for simplicity, while others choose ext4. (I chose ext2 for my current KDE neon setup.)
So first you'll boot up your bootloader in the /boot/efi partition. The bootloader will hand over to the /boot ext2 partition. And that will hand over to the rest of your system, in the / partition.

Linux multiboot is quite relevant - and it's important not to make errors here. A friend of mine wanted to install Debian testing on an external HDD (alongside his Debian stable installation on his internal HDD) but somehow his bootloader (on the internal HDD) got overwritten. (Note that the Debian installer can be pretty nasty.) Thus, his encryption keys got overwritten and he lost all the data he hadn't backed up.
He originally wanted to also install Fedora alongside Debian but now he is afraid of Linux multiboot.
And I want to install Fedora at side of my KDE neon, so that I have one newer Distro, with new stuff like PipeWire and the most recent software. And so I can switch between Gnome and KDE, get to know both desktops and see which one is better.
Finally, one word about openSUSE: It looked like a good distro. I really was interested in openSUSE Krypton. But then, they disabled F2FS, which for me is an absolute no-go, because that's my favorite file system. And I need F2FS for some of my USB flash drives (namely the ones that aren't formatted with exFAT).

So I'll install those three systems onto one 1TB NVMe SSD and put some other stuff (like a shared download folder) (in some NTFS volumes) onto my old 500GB SATA SSD.
- You da man! What about deleting from a multi boot system?
- Thanks so much dude, this video really helped me get my multiboot system setup
- I don't feel like dual booting yet but I'll keep linux on a USB incase
- Thank you for this video. Finally - so many detailed and advanced tips here for multi-boot - not a high-level stuff like in other YT videos, that promise much but deliver little. 👍
- This is one of the best Videos for Multi OS Guide. Helped me a lot, and rEFInd is a must. I recommend setting a command to deactivate Grub from installing itself back when you do a system update.
- damn... the most clear and complete guide on dualboot out there.. tks brow, amazing job
- hi, so with that setup each distro will have it's separate Home directory, but in case you want a shared Home directory between different distros would you create a (/home) partition separately? would it work that way?
- Thank you so much! After watching this, I am able to set up any hard disk with uefi myself, and now I also know how uefi actually works!
- So where is the (and Windows) part??? Ive installed ubuntu and now cannot get windows installed due to stupid UEFI problems.
- Hi Dorian, thank you for the video. I have one 250 GB SSD that has Fedora on it and I have a 2 TB HDD for storage. I am fairly new to Linux and am still trying to find the distro that I like the best. So far, Fedora is amazing, but I would like to try Parrot OS, KDE Neon, Debian, Arch, Endeavour and a few more, but I am not wanting to use a virtual machine because I feel it really lessens the experience of the OS. I was hoping to be able to use my 2TB HDD for each OS with about 100GB allocated per OS. I had to make an additional efi file and to try it out I install Ubuntu. I can now run Fedora and Ubuntu, but it is not that smooth as I have to go into the boot options within UEFI and choose which to boot from. When I turn the computer on it goes to the last OS that I was in and I cant get the boot option to show upon startup. Is there any way to add the options for Ubuntu and fedora or would I have to install the OS on the same Hard Drive?
- I have a dual boor system, I press F12 when I start it and choose what OS I want from whatever drive I have it installed on.
- Thanks for this great tuto ... neat and useful notes
I wish you show the same .. multi-boot with two Linux OS on Win 10
- What If I have a Windows PC and I want to use Kali Linux on it.I dont want to use the GRUB bootloader?How would I be able to do that?
