    Installing ArchLinux, can't find partition/root

    I've used Ubuntu Server earlier but decided to migrate to ArchLinux. I've followed the beginners guide on the official site, read the wiki and googled but can't seem to find a solution although I'm sure it's something simple.

    After selecting my ArchLinux install with Grub it can't find the partition specified for my root. One other partition boots but there is nothing on it so it can't find /sbin/init.

    I'll give you the information first and then the error message:

    disk/partition# UUID Purpose
    sda1 7e456a2c-c6b1-4458-a14a-1bd3e14043e5 Storage
    sdb1 f759577b-b219-438f-972b-73be9b57b633 Storage
    sdc1 0147f5cb-4501-4bcd-b55e-3bdcf656708b Storage
    sdd1 704c5080-06e1-4b43-a18a-00d61be4d0c6 Boot
    sdd2 61399044-f8b4-4904-8a12-c87065a42125 Swap
    sdd3 760aa8a4-6916-4bbe-a63e-df4885fa7974 Root
    sdd4 1017ec17-8bde-4afd-a594-144745d9fe71 Home

    On sdd1 which is the boot partition I get the following from 'ls -l':
    The menu.lst in grub looks like this (I got (hd0,0) from 'grub> find /grub/stage1'):
    grub menu.lst
    # (0) Arch Linux
    title Arch Linux
    root (hd0,0)
    kernel /vmlinuz26 root=/dev/disk/by-uuid/760aa8a4-6916-4bbe-a63e-df4885fa7974 ro
    initrd /kernel26.img
    # (1) Arch Linux
    title Arch Linux Fallback
    root (hd0,0)
    kernel /vmlinuz26 root=/dev/sdd3 ro
    initrd /kernel26-fallback.img
    sdd3 which is the root partition looks like this with 'ls-l':
    I grew frustrated and input the uuid for all partitions and the only one that got recognised and booted from was sda1 but that contains nothing so it complained about not finding /sbin/init.
    In every other case I get the following error:
    Waiting 10 seconds for device /dev/disk/by-uuid/760aa8a4-6916-4bbe-a63e-df4885fa7974 ...
    Root device '/dev/disk/by-uuid/760aa8a4-6916-4bbe-a63e-df4885fa7974' doesn't exist. Attempting to create it.
    ERROR: Unable to determine major/minor number of root device '/dev/disk/by-uuid/760aa8a4-6916-4bbe-a63e-df4885fa7974'.
    You are being dropped to a recovery shell
        Type 'exit' to try and continue booting
    /bin/sh: can't access tty; job control turned off
    Why does it not recognise my partition when I identify it by UUID? I might need to mention that I'm doing all the OS partitions on a USB-memorystick. The sda1 partition is a regular SATA-disk but the other SATA-disks (sdb1, sdc1) is not recognised either.

    Any ideas about what my problem/solution is or what more information might be needed? Thanks in advance!

    what does blkid report?
    if you use root=/dev/sdd3 does the system boot ... is it just uuid that causes a problem?

    ... it's quite a while since I did a fresh install but I'm sure I was asked as part of the install if boot from USB was required ... did you answer yes to this?
