3 years later, on arch, still works, thank you ❤

23/4/2023 Still works!!! I followed the steps on Fedora 37 and everything worked fine, thanks very muchhhh!!

Well done ! Thank you.
I found this answer to making grub menu display at boot:
"Menu will appear if you press and hold Shift during loading Grub, if you boot using BIOS. When your system boots using UEFI, press Esc.

For permanent change you'll need to edit your /etc/default/grub file:

Place a # symbol at the start of line GRUB_HIDDEN_TIMEOUT=0 to comment it out. If that line doesn't exist, then you can comment out this line instead: # GRUB_TIMEOUT_STYLE=hidden, and then change GRUB_TIMEOUT=0 to GRUB_TIMEOUT=5, for instance, to give the grub menu a 5 second timeout before it automatically logs you in.

Save changes and run sudo update-grub to apply changes."

this worked well, but had to convert from MBR to GPT. thankfully you posted another video on doing that WITHOUT losing any of my data

Thanks very much, I completely removed Windows 10 and installed Mint instead, but now I am thinking to go back on dual boot just in case.

[richardgil]

man... i just love you! i spent over 12 hours trying to do it, and none of the other tutorials helped. yours just did it... TANK YOU VERY MUCH!

Great video, needed to dualboot quickly to install a bios update (vendor only giving windows executable) but this made me quickly install windows, install bios update and remove windows again.

Normally tech tutorial videos offer little help but THIS ONE is 10/10. Couldn't get grub2 to work for whatever reason on a gigabyte mobo but no worries, I still can boot either os. Thanks a bunch friend!

How do you unmount a partition if that's the one you're using and you can't run GParted any other way?

[suhaskuthnikar]

Bro you really saved my time i was unable to install install windows over my arch linux for my secondary device which i needed to attain interviews ♥️⚡

[mtitania]

Thank you so much for an easy and effective tutorial!! Was able to add a windows OS to ubuntu no problem!!!

[mathildaleina]

How do you unmount and resize?

It says "could not unmount /dev/sda2". What should I do here?

[jacobadams]

WOW!!! This is the best channel EVER!!! Thank you, TechIN!!!

Should I unmount my main partition? I have doubts about it, the computer may no longer boot, even if I don't have important data and know how to recover the computer, I would rather unmount my main partition.

[sooryanarayanans]

Is there any problem if we don't unmount the disk?
Mine it's showing
Could not unmount/dev/sda2
#unmount -v'/'
unmount:/: target is busy

[protoyeen]

Mine installed slightly differently (probably because I'm using Xubuntu LTS) but it works out, grub menu and everything works so far, just finishing on setting up Windows 10

[unmeshguleri]

Thanks man, such a helpful video! I installed Win 8.1 by following your steps.

[dibyendumondal]

Everything was fine but my bootable pendrive was only detected by my laptop only when I made it bootable using Rufus...
When I made it bootable using Ubuntu 'Disks'/Gparted my laptop was unable to detect the bootable USB..
However, thanks for the smooth guideline.. ✨❤️

[mortelismercury]

I have only one partition so it wont let me unmount it, what do i do?
