[Solved] ERROR: Unable to find root device 'UUID=95e0c7c1...

After installing arch linux following the procedure in the wiki and on other websites I still unable to boot into linux from GRUB, getting the following message:

starting version 228
[    1.070026] firewire_ohci 0000:03:03.0: failed to read phy reg 2
ERROR: device 'UUID=95e0c7c1-22c3-4daf-ad93-88f0605c324f' not found. Skipping fsck.
ERROR: Unable to find root device 'UUID=95e0c7c1-22c3-4daf-ad93-88f0605c324f'.
You are being dropped to a recovery shell
    Type 'exit' to try and continue booting
sh: can't access tty; job control turned off

However, if I go into the advanced options in grub and launch Arch with fallback initramfs it seems as though everything boots normally and I am presented with the arch login screen.

I know there are many other threads and discussions online about this issue but so far none have solved my issue.

Any help would be greatly appreciated.

ERROR: Unable to find root device 'UUID=95e0c7c1-22c3-4daf-ad93-88f0605c324f'.

Does that UUID match the output of 'blkid' for your chosen root partition?

That last bit is a very bad idea™ - no wonder you have issues. Just use the Arch documentation.

Re: [Solved] ERROR: Unable to find root device 'UUID=95e0c7c1...

Because I can't boot into the installation, I inserted the live-cd, mounted my root partition (sda4) and chrooted into the system. sda1 is my mac's ESP partition, sda2 is the OSX installation. Then I get the following:

lsblk

Try regen initramfs with mkinicpio after you booted with the fallback, and then try again.
