Installing Ubuntu on Parallels desktop (/dev/disk/uuid error)

I recently started to develop some software for the beaglebone, and since I do most of my stuff on my Mac, but developing for the beaglebone requires a "real" (sic!) Linux machine, because the openembedded build system used for managing your cross compiler etc., does not really run on Mac OS X, I installed a virtual ubuntu machine on my Mac.

Marcus from interactivematter gave me a nice link to get a minimal installation on a virtual machine, which can be found here:  http://nut-bolt.nl/2012/ubuntu-virtual-machine/

Only problem: it does not work, after installing you try to boot via the bootloader and the bootloader complains with something like

Alert: cannot find /dev/disk/uuid-SOMELARGENUMER

I banged my head against the wall a couple of times, and tried to google the problem, but most of the problems were very specific about update problems withing Ubuntu proper. I found a solution in the end, which I write down now for eternity:

1. Stop your virtual machine
2. Go into the virtual machine settings
3. Go to the harddisk settings
4. Change your Harddisk from SATA0 to SCSI 0 
5. Reboot, be happy.
