I want to have two OS:ess one is arch (btw) and the other i want to be win10-11. I have already got another empty disk for putting it on. I think I got the knowlage but I do not want to find out I don't when it is too late.
I want to select which one to boot with grub and the hardisk is 120GB.
And to clarify I have arch already set up and done. Jus' need windows for some windows specific shtuff!

that's the exact setup i have, arch in a disk and windows in the other, heres how i did it
install linux first, set up grub and everything
with the linux disk disconnected install windows, it will install in the only drive on the computer and setup it's bootloader and stuff
back onto linux mount the windows boot partition anywhere and install os-prober
redo grub config, it will find windows and add it automatically
.aw dual boot with windows

you will need ntfs-3g and os-prober
with them in separate drives it's very easy since you can just disconnect one

Thank you! Although.. I lost you at "back onto linux mount the windows boot part...
once windows is installed reconnect the linux drive, boot into linux (you'll need to manually select it in the firmware) and mount the windows boot partition somewhere, where doesn't matter, i did it at /mnt/winboot install the os-prober package and rerun the grub config
the wiki has the commands, I'm not on my pc rn so I can't check the actual things easily

mm
I'm kind of new to his atm. Would you be so kind and get back to me later when you are on your computer?
Also the bootable USB
I tried a tutorial but all of them start on windows

sur lmk when you're on

so these are my drives
you can see nvme0n1 has 3 partitions, efi, swap and some other stuff, that's my linux install
sbd has 3 partitions as well, but isn't mounted, that's my windows install in a separate drive
sdb1 is the windows bootloader, the 100mb one
this can be confirmed by running blkid and seeing it has the EFI system partition label
so all i have to do is mount the windows efi partition somewhere, like /mnt/winboot
install the os-prober package and run the grub config
it automatically finds windows and adds it to the settings
see how it says 'Found Windows Boot Manager'
so now when i boot grub will have the options to boot into arch or boot into windows
os-prober is just a package, it has no config needed just install

Mine detect the window EFI file and boot into it
But the second reboot the file somehow is deleted and not found
I have to remount in linux and then reboot for it to work

The mount get removef after rebooting is this normal ?

yes unless you add it to your fstab the system won't know it needs to mount it, and you don't have to, it only needs to be done once
you may want to mount the windows data partition, in my example it is sdb3, if you want to share data, but it's also not needed, i didn't

Idk it work once and then, when i try to reboot again i get the disk not found / no such device errors
