View Full Version : [ubuntu] No root file system is defined. question

April 7th, 2011, 11:08 PM
When I get to installation step "Allocate drive space" I get this message,

"No root file system is defined.

Please correct this from the partitioning menu."

What is the source of this error and what do I need to do to correct it?
I don't see a partition menu other than a choice of using the whole drive or a partition?

Below are the choices that I have made.

Specify partitions manually (advanced)
Allocate drive space

Choice are device (/dev/sda4) Type ((ext3) size) Mount Point (no choices offered) Size (42088 mb) used (670 mb)

boot looder is sda Windows 7

ext3 42088 MB

I am installing Ubuntu 10.1 on a seperate partition. Windows 7 is on another partition.
The machine is an ASUS A52F Laptop

I have done this before on two other computers and have never had a problem.
