Kan inte boota Ubuntu 11.04

Got a wierd problem trying to install ubuntu, or actually boot ubuntu 11.04 on a "hardware" ssd raid 0 setup. It just won't boot after POST. Tried installing it on one partition. Tried diffrent partitions such as /boot /root /swap... no luck. Even tried softraid and putting the /boot dir on a physical disc without any success.

Funny thing is when i gave linux mint 11 a try. It worked flawlessy on a hardware raid 0 setup.

So my question basicly is, what is it that linux mint 11 has that ubuntu 11.04 misses when it comes to running em on raid setups?

Comp: Asus Sabertooth P67 | i5-2500K @ 3.33 (Corsair H60) | Asus GTX560 1GB OC | Tagan piperock 900W | 8GB Corsair Vengeance @ 1600MHz | SSD: 2 x Corsair Force GT 60GB @ raid 0 | Linux Mint 11

Unless you have an expensive add in raid card not listed in your signature, then you don't have hardware raid. Your motherboard has fakeraid, which you can not mix with software raid. Last time I checked, Mint did not work with fakeraids. You will need to be much more specific about how you installed Ubuntu and what didn't work for any chance of figuring out what is wrong.

See https://wiki.ubuntu.com/FakeRaidHowto for more info.

Hence the "hardware" raid...

Okey some more info about the install:

Attempt 1: Ubuntu desktop 64bit

a) sata controller set to "raid mode"
b) raid arrey created via bios raid menu (ctrl-l)
c) Booting of a usbstick, runs ubuntu desktop 64 bit install on the entire newly created raid drive. (use entire drive as option)
d) Installation runs smooth without any problems
e) last step to complete: reboot and remove the usb stick
f) after the power on self test the startup fails and won't boot.
g) Tried all available boot devices (bootorder in bios) same problem

Attempt 2: Ubuntu alternate CD

a) deleted the "hardware" raid in bios and changed back the sata controller
