Need some recommendations.

Build a beast of a pc. Fancy 16 core X3D. 64 gigs of ram. 5099. Samsung 9100 and all that good shit. Going to install cachy on the fastest drive and windows on a different drive so no dualboot on same drive.

What are recommendations for bootloaders. Pitfalls to watch out for. I for the first tjme in a while need some opinions.
