Trouble understanding where intel-ucode.img needs to be placed

I was trying to load my intel-ucode as explained here https://wiki.archlinux.org/index.php/microcode#rEFInd.  I use refind-install script to auto detect my operating systems.

Device         Start       End   Sectors   Size Type

I tried using /boot/refind_linux.conf as the following

"Boot with standard options"  "rw root=UUID=5ca3bd25-5882-449a-a4d8-c52fe2f178cf quiet initrd=/boot/intel-ucode.img initrd=/boot/initramfs-linux.img"
"Boot to single-user mode"    "root=/dev/sda6 rw single"
"Boot with minimal options"   "ro root=UUID=5ca3bd25-5882-449a-a4d8-c52fe2f178cf"

However when I try booting with standard options, refined says that it can't find "boot\intel-ucode.imng" or "boot\initramfs-linux.img", but both of them are in the /boot. Where do these files have to be? Or am I just setting them wrong in the refind_linux.conf.

Thanks to anyone that can help

Re: Trouble understanding where intel-ucode.img needs to be placed

Remember, refind is loaded before the operation system; it's looking at the ESP, not at the root filesystem (which is where /boot/ is).

Re: Trouble understanding where intel-ucode.img needs to be placed

If, within your Arch system, the initfs is at /boot/initramfs-linux.img.  In which case the path in the command line should be /initramfs-linux.img  .  This is how my system is configured.
If, within your Arch system, the initfs is at /boot/boot/initramfs-linux.img.  In which case the path in the command line should be /boot/initramfs-linux.img (this implies there is a directory called /boot on your boot partition)
If, within your Arch system, the uCode image is at /boot/intel-ucode.img.  In which case the path in the command line should be /intel-ucode.img  .  This is how my system is configured.
If, within your Arch system, the uCode is at /boot/boot/intel-ucode.img.  In which case the path in the command line should be /boot/intel-ucode.img (this implies there is a directory called /boot on your boot partition)

My system has reFind installed, but it is not my primary method of booting.  I use EFI stubs.  My system does not have a /boot directory on the boot partition.  This leads me to think that your use of /boot/boot/ is probably wrong.

Edit: Scimmia said what I said with much fewer words.
