How can I install windows 10 as dual boot besides linux mint?

[radiant moon]

I need windows to use matlab for college

[quick gate]

do you have windows or mint installed right now

[radiant moon]

mint

forgot to add

I want to install 10 not 11 (11 eats the resources ;-;)

[quick gate]

1. shrink your main partition by at least 64gb
2. create a live windows installation drive using ventoy
3. copy the iso into the big partition it has
4. boot into the live windows installer
5. when it asks you where to install windows, select the unallocated are that you just created - be careful not to select your mint partition, it will overwrite your data
6. let it sit there and install windows
7. reboot
8. boot into mint again
9. run sudo update-grub
10. from there on, just make sure to always boot into mint - there, in the grub menu, you can select to either boot into linux mint or windows 10

[radiant moon]

how can I shrink the partition?

[quick gate]

install gparted, sudo apt install gparted
run it

[radiant moon]

om thanks

when I get home I'll apply all your steps

[quick gate]

k let us know about any progress

[golden talon]

you need to make a unallocated space in your hard drive using gparted
then just plug your windows 10 usb and select usb as boot device in bios/uefi and install windows 10.
on disk window select unallocated space.
rest you follow..
windows will palace windows bootmanager as first boot entry in bios so you need to change that to linux mint which named 'ubuntu'.

then most important part :
use: sudo nano /etc/default/grub
change timeout line from 0 to 5 or 10 what you like
and hidden to menu.

save these change using cntr+o and exit using ctrl+x

then run 'update-grub'

now you can select which os you want to boot during boot process

[radiant moon]

I installed it, what's next?

I freed some space

it's now 225 GB unused

[quick gate]

resize the partition, the second one

how much space would you need for apps, files, etc. on windows?

[radiant moon]

I guess somewhere between 80-100 gb

I'll continue later on

[quick gate]

resize the 2nd partition so it will be 380gb total (adjust if you need more or less space than that)
then go back to my first message

[radiant moon]

for some reason I can't resize it

@quick gate

[quick gate]

oh its because its still in use

[radiant moon]

then what to do now?

[quick gate]

download ventoy from github - https://github.com/ventoy/Ventoy/releases
run the VentoyGUI.x86_64 file in the archive to set up a ventoy external drive
https://gparted.org/download.php
download gparted live from here, see the link that is purple for me (because i already downloaded it)
notice theres another purple link at the right handside, you can use it to verify the downloaded iso but its not necessary.
move (or copy) the downloaded gparted live iso into the first and bigger partition that is named Ventoy, on your external ventoy drive. make sure to NOT touch VTOYEFI
boot into that drive, where youll be greeted with the ventoy-styled grub menu that you can use to boot into any iso file in your external drive (including the windowas installation iso later on). boot into the gparted live iso
there youll be greeted by gparted again, but this time without the issue of your main drive being in use.
then do what i told you earlier to do

you do have an external drive, right?

[radiant moon]

I have flash drive

[quick gate]

👍 use it

[radiant moon]

So I can't open ventoy despite running chmod +x

[quick gate]

whats the error

[radiant moon]

it doesn't even open the app in the first place

[quick gate]

try running it in the terminal

[radiant moon]

How?

[quick gate]

ctrl+alt+t
cd into the directory where you extracted the ventoy archive
./VentoyGUI.x86_64

[radiant moon]

Ok I opened terminal

I wrote in it chmod +x ventoy yet it didn't open

[quick gate]

run chmod +x ./VentoyGUI.x86_64 && ./VentoyGUI.x86_64. as it is, just copy & paste

[radiant moon]

It worked!

but it's in russian accent ;-;

NVM, I just accidentally clicked on russin language

[quick gate]

[radiant moon]

I pasted the iso in the first file

[quick gate]

[quick gate]

now resize your partition to leave enough free space for windows

[radiant moon]

what should I write in the new size?

I want the new disk to have 84 gb

[quick gate]

move the slider until there's about 86000 mb free to the right of the partition (it should say at the bottom of the popup)

[quick gate]

yeah that should be enough

now confirm it

[radiant moon]

I did it

[quick gate]

press the "Resize/Move" button

[quick gate]

ok now press apply

[quick gate]

confirm that you want to resize the partition

[radiant moon]

Ok I did it

[quick gate]

AFTER you run sudo update-grub
