How to install Windows 10 and Linux Mint Cinnamon dual boot on same Hard Disk ?

[lone frigate]

so what u need to do is determine bios mode from windows 10

or just disable CSM/Legacy boot suport in bios. from the very very beginning.

• install win 10 as uefi, then install Mint as uefi. done.

how to determine bios mode ?

[sharp ginkgo]

so bios is UEFi always ?

[sharp ginkgo]

i have UEFI bios in my PC

[sharp ginkgo]

how to install Linux Mint to dual boot with Windows 10 ?

[sharp ginkgo]

what means installing Linux Mint "as UEFI" ?

[lone frigate]

if u disable legacy/csm, u wont even see the option with the red x above.

[sharp ginkgo]

i can boot into Linux Mint media by UEFI

[sharp ginkgo]

problem is that i dont know how to make partitions for boot, UEFI and Linux Mint root

[lone frigate]

u dont need to

[sharp ginkgo]

or MBR and GPT

[lone frigate]

AS LONG AS U BOOT UEFI USB EVERY TIME from usb, then mint will just do nice co-install with Windows.

[sharp ginkgo]

i always install Linux with option , something different

Did you check https://discord.com/channels/628978428019736619/1296501856121393222 ? might answer a bunch of question then you can ask abbot what parts you are not sure about here.

[lone frigate]

just choose 'install alongside Windows"

[sharp ginkgo]

why ? idont like it

[lone frigate]

then dont dual boot

[sharp ginkgo]

i want know what is happening in the install

so something else, is not working any more ????

[lone frigate]

ur mixing modes, that's what's happening. DON'T MIX BOOT MODES

[lone frigate]

like this always or gtfo

[sharp ginkgo]

in Linux Mint 21, something else-option worked full

[lone frigate]

and choose 'alongside' option

[shell anvil]

When you have Windows installed first and you plug in your USB containing the burned Mint ISO, then boot from it, you will have an additional option in the install process to install Linux Mint alongside Windows. Then the process is a bit different from there.
Other options are to erase your entire disk and only install Linux Mint or to do a manual install where you can arrange partitions by yourself.

[sharp ginkgo]

i want to use manual arrenge option

there is Windows boot manager - partition and EFI partition

but i dont know what to do with them and where to install GRUB ?

what alongside with Windows, really do to the HDD ?

[shell anvil]

Might be easier for you to understand visually

[sharp ginkgo]

that has not even WIndows boot loader on the disk ....

I have UEFI bios, that video is not for UEFI

[shell anvil]

If you choose the 'install Linux Mint alongside Windows Boot Manager' option, it's much more simplified because then all you have to do is choose how much space you'd like to allocate to Mint.

[shell anvil]

UEFI has nothing to do with the install process. It only matters when you're trying to boot Mint from your flash drive to perform it.

[sharp ginkgo]

so you think there is no EFI partitions with UEFI system ?

and no Windows Boot Loader ? why i have those ?

[shell anvil]

You have Windows Boot Loader because you have Windows installed first and it has its own loader

When you install Mint alongside it, Mint will install Grub to help you choose which OS to boot into when you turn on or restart your computer

EFI is the partition mandatory for UEFI boot

All you need to do is handle which partitions you'd like to assign to Linux Mint.

If you're not sure and don't want to mess with it manually, choose the option to 'install Mint alongside Windows' and go from there

[sharp ginkgo]

put same video with Linux Mint 22.1 ?

[shell anvil]

Version doesn't matter here. It's been the same process for years.

[sharp ginkgo]

no it is not

or then i have forgot something in time

[sharp ginkgo]

so i indeed, need to make another EFI for Linux 😮 😮 😮

[shell anvil]

If you insist on a newer video, here you go:

[sharp ginkgo]

thanks buddy 🙂 🙂 🙂

my mistake was, not making EFI partition for Linux Mint and choosing it to Boot Loader - partition

[sharp ginkgo]

this did solve my problem : https://unix.stackexchange.com/questions/758353/resolving-dual-boot-issue-windows-not-showing-in-grub-menu

For me I also encounter this problem recently when I upgrade my grub2 package from version 2.06-13 to 2.06-13+deb12u1. The solution is to uncomment this line in /etc/default/grub:

GRUB_DISABLE_OS_PROBER=false

Then run sudo update-grub to let GRUB scan for Windows 10.
