I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD.
I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table.
In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.
After following your directions completely, when I choose to install, I still have the same problem. No partitions show up to install from. It's just a blank box and I still get the same error.
In Gparted it show:
Partition File System Label Size Used Unused Flags
unallocated unallocated 698.64 - - /dev/sda1 ext2 / 698.63 11.03GiB 687.60 boot unallocated unallocated 2.49 - -
I close out Gparted and then click Install Ubuntu on the desktop. It asks me to choose a language, make sure i'm connected to the net, download updates, install 3rd party software. I click next. Then the option to choose where to install it comes up, however there is nothing to choose from. At the bottom it says /dev/sda. I click install and it gives me the error "No root partition is selected check your partition table" ???
I am not getting an Installation Type choice on the third screen. I do not know how to take screen shots of what I am doing either, so I am doing my best to spell out what is happening:
On the desktop I open the shortcut that says "Install Ubuntun 12.04.1 LTS.
The first screen that appears says Welcome and it asks me to choose a language. I select English and click Continue.
Screen 2 says Preparing to Install Ubuntu. For best results please ensure that this computer has at least 4.5 GB of available space - Check Is connected to the internet - Check Download Updates while installing - Checked the box Install 3rd party software...mp3, flash etc... - Checked the box
Screen 3 says Installation Type.
There is a box that apparently should show where the OS is going to be installed to.
The top of the box says Device, Type, Mount point, Format? Size, Used Below that is a large empty space Towards the bottom there are buttons "New Partition Table... Add... Change... Below that it says Device for boot loader installation: /dev/sda
Then on the bottom right of screen is Quit, Back, Install Now.
The first two buttons at bottom are obvious, but when I click "Install Now" I get the following error:
No Root file system is defined. Please correct this from the partitioning menu.
