I have found that removing the EFI flag from the partition also works. I just choose which is easier, since removing some nvme SSDs can be buried under a few components depending on the motherboard

I really hope Windows doesn’t alter that. My Gigabyte motherboard forced me to boot into windows after a hios update, because the Linux bootloader was not registered…

I had a similar setup (Endeavour OS + 3080). While most daily tasks worked fine I had some large annoyances.

• Monitor Sleep would sometimes prevent VRR from working afterwards
• Actual sleep would sometimes force me to reconnect my second monitor.
• Hybernation was completely broken
• VRAM swapping does not work at all, leading to stuttering instead of simply degraded performance.

I am sure I missed some more minor ones, but there were the main reasons I got an AMD card
