This guide provides a detailed plan for your fresh system install, incorporating your specific drive usage, CachyOS with Btrfs for snapshots, and the GRUB bootloader, accounting for the Calamares installer.
Summary of Your Desired Disk Layout:
- /dev/sda(SanDisk SSD PLUS 931.5G): Scratch/test drive for Linux installs. (Will be ignored for this main plan, as you'll use it for temporary installs.)
- /dev/sdb(Samsung SSD 850 931.5G): Dedicated developers' files drive for Linux. (Will be formatted.)
