Hello,

I am currently using a dual boot Windows 10 + Manjaro KDE.

Right now i'm using Windows for gaming and Manjaro for pretty much everything else (Development, music production, web surfing, text editing, etc.).

Seeing that gaming on linux is way more accessible than before with to proton, and that the end of life of windows 10 is in roughly a year, I would like to use linux for pretty much everything (including gaming) and keep Windows on the side, as an emergency solution in case something goes wrong.

To do that, i would like to reorganize the partitions, but I am unsure of the safest way to do it.

Right now, my disks look like this :

> lsblk -f

sda is a ~200 Gb SSD and sdb a 1Tb HDD. The windows partition is on sda4 and the manjaro partition is on sdb3, meaning that windows takes about 10s to launch while manjaro takes 1 or 2 minutes. To fix this, I would like to move my Manjaro partition on sda, alongside windows.

My best guess to do this would be to :

1. Backup all important data from windows and Manjaro (on an external hard drive)
2. Use window's partition tool to create a partition for Manjaro on sda
3. Install Manjaro on sda
4. Reorder the sdb partitions to clear the old Manjaro data

Can something go wrong with this method ? And what are the partitions I should ABSOLUTELY do not modify ?

As a subsidiary question, I am wondering if Manjaro KDE is a good distro for my needs.

I have been using for about two years so far with no major issue, but I have heard that for some people this ditro can break pretty easily. That being said, I use almost no package from the AUR, so maybe that's why ?

Do you have any recommendations regarding distros for mainly dev/gaming? And is it possible to put KDE on it easily ? I like the way it feels/looks

Anyway, thank you if you have any advice or opinion on this.
