I'm currently using a dual-boot setup with Windows 11 and CachyOS, and I've been using rEFInd as my boot manager. Everything was working fine until I had to replace my power supply unit (PSU) and reset the CMOS to troubleshoot a different issue. Since then, my system boots directly into Windows without showing the rEFInd menu, and I can't find anything about CachyOS, Linux, or rEFInd in my UEFI settings. I have an A320MH motherboard and the BIOS version isn't updated. What steps can I take to regain access to my Linux installation?

That's strange if rEFInd isn't in the UEFI boot menu at all. You'll want to check if the EFI partition still has the rEFInd files. If not, you might have to reinstall rEFInd from within Windows, but you might need to access that EFI partition first.
Have you checked your BIOS settings? Sometimes resetting the CMOS can revert settings back to defaults, which might affect the boot options. Make sure everything is configured correctly for rEFInd to work.
If your BIOS has a "boot from file" option, you can try to locate and boot the rEFInd application directly from there. Alternatively, you can also create a new boot entry using a USB drive and the `efibootmgr` tool. Just look up the instructions on how to use it if you're not familiar.
