Comment 3 for bug 614399

Here is the kickstart file I used.
Note that I investigated many different combinations of options without success (zerombr or not, bootloader location on mbr or partition...).

Also, I do not have the option to change the drives order from the bios, in my case the USB key is always sda and the disk where the installation is made is sdb. I have not found a way to change this order elsewhere.

I did not have this issue in karmic using the same target systems.

Thank you for your attention,
Stephane.
