Downloaded it and trying it on a virtualbox. Very impressed with the new look. It's very well done, has a good 'feel' to it and overall gives a very polished impression. The installer is also very consumer-oriented, which is a nice touch.

now we need a smartbook or tablet with similar specs (IPS or better screen, 10+ hours battery life) as an Ipad to run it. Preferrably with a slightly stronger CPU (dual core Cortex-A9). I would buy one!

Ok, upgraded to 10.04 and been going nuts ever since. Simple: it won't boot.
The excuse:

ALERT! /dev/disk/by-uuid/XXXXXXXX does not exist. Dropping to a shell!

I've been digging around for any sort of solution (and even tried some) but to no avail. Finally, I've located a post someone wrote about typing 'exit' and having his system boot.
I tried it and.. it worked! Then I tried again and it failed a few times till it worked again. Confused? So am I.

ls /dev/sd* showed something rather peculiar: sdf (the hdd) and the partitions inside it only agreed to appear 20 seconds or so after dropping to shell. To make things even more bizzare, WindowsXP which is on the same HDD boots just fine, as usual.
I've done a complete reinstall, dist-upgrade, the works, nothing changes it.
Like I said, I've googled around and nothing helpful came up. Any ideas?

My system relevant(?) info:

edit: some more info about my bios - My IDE (250G) HDD is set as none in the bios (not auto detect or anything) and my boot HDD is the Sata one (sdf). My boot partition is the same as / and my installation uses my old swap partition on the IDE hdd (sde2)

[TransformX]

Another weird bit:

$ ls /dev/sd*
/dev/sda /dev/sdc /dev/sde /dev/sde2 /dev/sdf /dev/sdf2
/dev/sdb /dev/sdd /dev/sde1 /dev/sde3 /dev/sdf1

$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sda1 / ext4 errors=remount-ro 0 1
# swap was on /dev/sdf2 during installation
UUID=5aca2eaf-a841-4694-978b-e4b9cdb04848 none swap sw 0 0

No such thing as sda1 in my device list..

[Haig]

I had a similar issue where the UUID in fstab did not match the ones listed in menu.lst

I followed instructions from user "chrisccoulson" on this thread and got it back to booting properly:

http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=813090

[TransformX]

Switching my fstab to be uuid based didn't fix it, neither did an upgrade (mentioned later in a link to a new thread).
I find it weird that SDE and SDF are only discovered about 20 seconds after dropping to the shell. They simply don't exist before that, either by UUID or by /dev/sdX location.

[Marshmallowman]

You could set a startup delay for the hdd in the bios. (if your bios allows it)

It maybe a band aid, but worth a try.

[TransformX]

I'm not sure my bios allows it, but I still don't get why my WinXP boots almost instantly when it's just another (2nd) partition in the very same hdd.

[UtwigMU]

You could replace UUIDS with sda etc... I had similar issue when I was trying to clone Suse and since it listed disks by IDs it didn't boot. I edited grub and fstab and added partitions instead of UUIDS and it booted. Just an idea, I'm not sure it's the correct solution.

[TransformX]

Didn't work either.. apt-get dist-upgrade kind of helped, sometimes it boots all the way.
