Can't mount root partition

I just installed arch on the hdd of my Lenovo Thinkpad 560Z laptop (old'ish, previously had win98). I had to do the installation on another computer since couldn't usb/cd/network boot on that one.

Now when I'm booting it, GRUB is loaded fine, after that I get

ERROR: device 'UUID=xxx' not found. Skipping fsck.

And I'm booted to rescue prompt. I tried using both LABEL and UUID in fstab, same error with both (even when using LABEL, the UUID is printed in the error message, and it seems correct). I also see no block devices when listing /dev from rescue prompt.

HDD model is IBM DKLA-24090.

Any pointers?

Re: Can't mount root partition

Could be a slow disk. Give it a few minutes at the rescue prompt and see if the disk appears in /dev. If not, then perhaps your initrd is missing some necessary kernel modules. Try booting the fallback image (which should have all modules) and see if that mounts your root partition okay.

Didn't appear after a while. Booting fallback image just freezes after 'Loading initial ramdisk ...' message. (Waited there around 20min, tried twice)

Have you checked /boot/grub/grub.cfg to see if the UUIDs in the Arch menu entry are correct?

Checked, they are all correct. Could the issue be that the computer I used to install the system was 64bit? I installed i686 system though.

Re: Can't mount root partition

Same problem after i installed arch end I've formated hdd and intalled for second time.
If you are in the same situation , the rudimentary way to solve it is to install (or maibe just partition from a livecd) a different  distro (i have used mint) and after to install again arch .
For some reason if i partition disk from the arch install image (parted,fdisk) i will have same error with grub.

Re: Can't mount root partition

I have the same problem. First time to install. I have an Asus UX301LA and followed this guide in order to install it (up until "Post install", since I became stuck with this problem). I also created three partitions, one FAT for /boot and two ext4 for / and /home. Both the latter were encrypted with cryptsetup like in the guide.

I also use RAID 0. (I'm not sure what type of RAID I'm using - software/firmware)

When in recovery shell and listing /dev i can see my actual physical disks, (sda and sdb) but not the ones I have installed on, and which were encrypted (md126p2 and md126p3). I also cannot see any block devices under /dev/disk. (There is no "by-uuid" for example).
