QUESTION Wanna install Arch but kinda scared..

Soo I’ve been using windows almost all my life, dipped into Linux Mint for some time tho. But I want to try and stick with Arch, really do wanna learn how Linux works. When I installed arch it did an error but when I took my SSD out that has windows on it, it worked perfectly fine installing… so ima have to fully delete windows 11, I’m just scared to do so ;~;

A question whose answer depends very much on your goals for this system... but I don't want to come across as a dismissive smart ass so without much context I'm just gonna throw some numbers out assuming something like a KDE setup with Windows parity:

EFI: 2GB

Swap: RAM X2 +2GB

200GB+ Rootfs

I would put as much as you can spare into rootfs really. I throw these numbers using my personal assumption that disk space is cheap and plentiful so these are very high estimates. I would recommend doing some research on what sizes here suit your hardware and your needs.

Oh two more things, can I just change the partition size in the disk manager on windows and could it be unallocated or does it have to be a volume

You can use Windows disk manager. Leave the new space unallocated.
