[SOLVED] reFIND intel-ucode and macbook pro-can't find intel-ucode.img

Hi all,

I am trying to get the intel-ucode drivers going on my mbp. Reading the wiki here https://wiki.archlinux.org/index.php/microcode#rEFInd

and I added these lines to /boot/refind_linux.conf

"Boot with standard options"	"root=UUID=<UUID> rw initrd=/intel-ucode.img initrd=/initramfs.img"

when i boot, it fails and says it cannot find intel-ucode.img or initramfs.img. I've also tried

"Boot with standard options"	"root=UUID=<UUID> rw initrd=intel-ucode.img initrd=initramfs.img"

and

"Boot with standard options"	"root=UUID=<UUID> rw initrd=/boot/intel-ucode.img initrd=/boot/initramfs.img"

all of which give me the same error message.

I verified that intel-ucode is installed. The root=UUID matches the / mountpoint in my fstab. I do NOT have a separate boot partition.

help

thanks. . .

care to elaborate on this?
uefi by definition requires a boot partition in the form of the ESP

Sorry, yes to clarify. I have a seperate partition that is already in place by osx that contains the EFI information. That's /dev/sda1. I installed reFIND and not anything like grub or syslinux.

The linux kernel and intel-ucode.img live in /boot, but that's /dev/sda5, which is the / partition.

thx

I believe that the kernel and initrds need to be on the ESP.

I believe that the kernel and initrds need to be on the ESP.

It does with some systems, like systemd-boot, but it doesn't with rEFInd. You do need to make sure it's reading from the correct partition and that rEFInd has drivers for the filesystem.

Okay, I'll take your word on that.  I installed eEFInd on my daughter's MBP using my standard approach of mounting the EFI partition on boot, so I know that works.  I have not tried it the other way, but have no reason to suspect it won't work.

Re: [SOLVED] reFIND intel-ucode and macbook pro-can't find intel-ucode.img

Thanks Scimmia,

that was it. I bypassed the refind_linux.conf, rebooted and looked at the boot options that reFIND uses by default. It was using root=/dev/sda5 instead of the root=UUID=<UUID>. I swapped over to that and all is well.

Thanks for the help.
