I choosed running a VM instead of dualbooting for 3 reasons

• Privacy : I don’t trust Microsoft, so I’d prefer Microsoft not to run bare-metal
• Enjoying the process : learning more about QEMU/KVM, virtualization and passthrough was a valuable experience for me
• Windows tends to mess with GRUB partitions, sometimes even on other drives

100% agree, ty for your answer

I’m quite reluctant to dual-booting Windows because I have read online that Windows Update likes to mess with other partitions, sometimes even completely separate drives… Anyway thanks for your answer
