I followed your instruction, but I can’t boot ubuntu by pressing the media direct. It just loads windows 7.

I have a dell xps m1530.
My partitions are:
OEM Partition ( /dev/sda1)
System Partition( /dev/sda2)
Linux Root Partition( /dev/sda3)
Swap Partition (/dev/sda4)

After installing ubuntu (with the bootloader located at sda3) the pc restarts and boots in windows. There I inserted the Dell Media Direct CD and runned rmbr (as administrator):
cd\
e: (because my dvd-drive is e: and not d:)
cd dellkit
rmbr DELL 2 3

Shut down the pc and tried to boot ubuntu.
But my laptop just boot window 7.

What’s the problem??? Do you know any solution??

Thanks in avance,
Pigmaster
