Ubuntu on Alienware M17x

Hello all. i am trying to install Ubuntu on my m17x, via wubi. the installer downloads the .iso and completes the file copying. but when i boot to Ubuntu, it want to do the rest of the install, and that's fine. my problem is that under the install i get a error messages that says:
no root file system is defined. please correct this from the partition menu
but i can't access anything.. and my only option is to shut down..
does anyone know what to do?
thanks in advance

 

Did you set up any special partitions when you installed or did you go with the defaults?

 

if you already have an ubuntu partition ready to go, why not burn an ubuntu install cd, or create an ubuntu install USB key?

 

Did you define the root file system...?

 

i don't have an extra partition, and i am actually trying to avoid the whole thing with repartitioning, and the grub bootloader..
i can't define the root system like a normal install, beacuse it's automated.
i've searched google a lot but couldn't really find anything

 

Wubi is a bit buggy, and I don't mean any disrespect, but if it doesn't work, it's not really worth the hassle if you can't find an easy fix. There are a lot of threads you can find about this error but I didn't find a definitive looking solution.

You can resize your partitions and make room for a real linux installation, that would be my advice. Of course you should back up your important personal data since there is always a risk associated with resizing partitions. An Ubuntu CD will let you resize with gparted, or direct from the installer.

 

Wubi worked perfectly for me... it wasn't worth the trouble keeping it though. I tried out ubuntu with Wubi first, and then just made a partition for ubuntu alone

 

i will consider a real linux install, thanks for the answers
