Error 22 in Grub with FakeRAID

[Guest]

Hi guys!

I have a computer with 3 HDDs, 2x500Gb in Promise FastTrak 378 RAID mirror with Windows in the first partition and Kubuntu in second; and 1x120Gb with a Linux Boot partition and two another backup partitions.
I could install Kubuntu 9.04 in the FakeRAID array, using LiveCD and installing dmraid. I'm sure that Kubuntu is installer because I always can boot from LiveCD and see this partition.
If I boot from the RAID array I can boot to Windows and use the computer, and I want to keep this if everything corrupts I have Windows at last. So I've instaled Grub in the first partition of my 120Gb HDD from the Kubuntu installer. At this time it's not so importanting to let Grub boot to Windows because I can boot to it from the RAID array.

Sorry for asking, I am very newbie with Linux, and I get so confused to do simple things like this. My problem is everytime I try to boot to Kubuntu by running Grub from its partition, I have "Error 22". I understand that is "partition not found". I've checked with some help from internet, and seems like my grub is correctly configured. I am sending a copy of my menu.lst from grub.

Please guys! What can I do? What config I've missed from grub?

Thanks a lot!

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default		0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
