“No root file system defined” error while installing ubuntu

1
Hello,

I got Ubuntu to run off of my USB drive, but I cannot get it to install onto my hard drive.

The installation guide shows a step where the user gets to choose between "Install Ubuntu alongside Windows", "Replace Windows with Ubuntu", or "Something else".

I don't get that option. Instead I am just pushed into the partition table, except all of the buttons, like "New Partition Table", "New Partition", "Edit Partition", "Delete Partition" are grayed out.

If I try to continue, I get the error "No root file system defined"

I got the same problem with Ubuntu 11.10 and 10.04 LTS.

Another guy posted a video of the same problem on youtube if you want to know what I'm looking at.

Please keep in mind that I'm new to this, and don't really know what I'm doing.

Any ideas?

Thanks in...

When you use WUBI to install, you have absolutely no need to change your partitioning. WUBI creates a large Windows file that becomes the entire Ubuntu hard disk, and then installs within that file. For 12.04, using a 19-GB area will be making it very tight. If you still want to use your G: drive, format it back to NTFS and then select it in the WUBI installer; the installer will create the necessary file and format that "virtual disk" to ext4, then install 12.04 into that space. When installation is complete, your 12.04 system will contain an additional directory named "/host" which gives access to the Windows drive on which it is installed. If you want to access your C: drive's files from inside 12.04, you need to put the WUBI installation on C: rather than G: though. Since it's just another file to Windows, it will not interfere with your Win7 system.

I have a somewhat similar installation on my laptop, which has two Windows drives. I told WUBI to create a...

Question:

I am new to linux/ ubuntu and just downloaded the v11 of ubuntu to learn linux. I faced this "No root file system is defined" error while trying to install it. This is how I was proceeding -

Downloaded ubuntu v11 from the ubuntu.com website, wrote the iso into a bootable cd, and then got into the linux installation process on restarting; everything fine till here.

In one of the screen during installation, there are three choices - install alongside windows, something else etc.. Since I have windows 7 in the C drive, I selected the first option - "Install alongside another OS".

Let me interrupt here to give my existing system details - HardDisk size: 640GB. Number of existing partitions - 5 C drive - label windows - 160GB - has windows 7 installed D drive - label linux - 160GB - does not have any data E drive - label backup - 100GB - has some data F drive - label entertainment - 100GB - has some data G drive - label...

Is there a hard drive with more than 8GB? Any existing partitions (or a MBR/GPT) on it? Does it show up in sudo parted -l or sudo fdisk -l?

Can you "+ / - / Change" anything on that last screen? Or is there an earlier screen where you can pick a different option like "Install alongside windows / Replace windows / Something else" where you can pick a different option? Similar to this:

Take a look at these related questions, you may need to create/format some ext partitions using gparted, or even a new MBR/GPT, or just pick some from the last installer window (the one in your image). Or possibly sudo apt-get remove dmraid

And in case the above are no help whatsoever, the Mint installer runs ubiquity (an apparently customized version 2.18.8-1linuxmint8), "ubiquity is a graphical installer for Ubuntu, written largely in Python, using debian-installer (d-i) as a backend for many of its functions."

At least on XFCE it does, you can double-check yours by...

I am trying to install Ubuntu 12.04 using WUBI.exe from within Windows 7. All goes well but when it restarts and installation proceeds it gives and error “No root file system defined”. I have tried booting from live USB and Live CD but the same error occurs. Then i downloaded 11.10 version and booted into it using live USB but same error occurs there.

Now the thing is that I have 4 partitions on hard disk: 1- C: 147GB (with Windows 7 installed) 2- D, E which I use for file storage in Windows 3- G: 19GB NTFS formatted from Windows.

I am trying to install Ubuntu into this G drive. I want to keep my Windows 7 files and installation intact. I have tried it a while ago for 11.10 and at that time it all went super smooth. I have tried rebuilding the partition table from cmd.exe in Windows and i have also tried by formatting my G drive to ext3 using Easeus Partition manager in windows and then installing using wubi but wubi.exe didn’t detected the partition formated to ext3....

Hello, Townsheriff.

Are the following assumptions correct?
+ The Acer S5 is one of the really recent powerful ultrabooks. Actually its name is Acer Aspire S5 (plus some further number which specifies the exact type.)
+ It comes with Windows 8.1 64-bit pre-installed.
+ It does not use Bios plus MBR boot.
+ It uses EFI boot instead.

Which Mint 17.1 edition exactly are you trying to install? A 32-bit edition? A 64-bit edition?

Provided my assumption that this notebook uses EFI boot is correct, you will need a 64-bit Mint 17.1.
Provided my assumption that this notebook uses EFI boot is correct, you must make sure that the Linux Mint 17.1 live system boots up in EFI mode.

Does all this ring a bell?

Irrespective of my questions asked above, I found this note on running Linux on Acer S5:

Linux runs fine on the Acer Aspire S5… Provided you set the SATA controller to AHCI in the BIOS.

I am new to ubuntu, and was installing ubuntu 11.04 from a CD. I booted up the CD and went to the installation process. I got to the step where it asked me to allocate my drive space. The window above with the columns titled mount, drive, etc., was completely empty. I didn't know what to do, so I pressed continue anyway. Another window appeared saying that the root file system was not defined, and that I needed to define it from the partitioning menu, which was blank! I have looked everywhere for the solution, and there is a lot of talk about setting the mount point to "/". I understand that that, but where do I set it! I also have not gone through the same installation windows as everyone else. (My installation process seems to skip the window where you decide to install ubuntu or try it from the CD.)

x10!

I don't know why so many people struggle with the extra work of manual partitioning when they aren't quite sure what partitions they need or how to set them up. The defaults that the installer creates for you are just fine (and a lot less work! ).

Glad it is up and running, though (Y)

Remember, the typical newbie (to Linux) comes from the world of *Windows*, where you typically don't have to do this sort of fiddling. (In most cases, not even the NT-based versions of Windows require the amount of partition fiddling even a distribution like Ubuntu would *normally* require.) Though I know how to do it, I still find it a major pain.

Thank Heaven for Wubi!

It's almost *Ubuntu for Windows*, in that it installs (and uninstalls) entirely from most 32-bit versions of Windows (and is known to work with XP and Vista); however, it doesn't boot from there. (It boots from the OS Loader included with Windows, such as OS Loader 6 included with Vista, so...

If you have an Ubuntu installation CD made from an ISO you downloaded from Ubuntu.com, you'll notice quickly that your slim, shimmering, featherweight personal computer has no DVD drive. While this might be the only time you'll want to use the DVD drive, this is a time you want to use the DVD drive. But never fear! There are other ways. Mostly, that means following these directions:

Have a go at installing grub in Suse from Ubuntu: boot to the Ubu Grub screen and press escape. Go to the text screen as suggested and press c for command line. Enter this command: grub, then this command : find /boot/grub/stage1

If you get a list that includes this item: (hd0,4) then the Suse installation went far enough to install Grub in Suse. But did it go far enough to analyse the hard drive and put the Grub config file menu.lst in place? To discover that enter this command next: find /boot/grub/menu.lst.

If it did you will once again get (hd0,4) in the list. Then boot from the Suse Grub by doing this:

root (hda0,4)

kernel /boot/vmlinuz

initrd /boot/initrd

boot

When if you get into Suse, repair the bootloader in Yast, using "Step 2 - Reinitialise and Reinstall Grug" inthis Tutorial"

If you are an

Ubuntu

or Linux user, you may have experienced a situation in which the file system may have been damaged for unknown reasons. When this happens, you can repair the damaged file system and return it to its normal state using the

Ubuntu boot CD

. Accessing the boot menu can help you to detect any errors that may have occurred and help you address the crash correctly.

This article will show you how to address a damaged file system by using command lines to search for and find errors.

How To Repair a File System Error on Ubuntu

Boot your system using the Ubuntu installation CD, and then select

Test Ubuntu

.

Next, open a terminal, and use the command line

$ sudo fsck.ext3 -f /dev/sdaX

to launch a search for any errors. All errors found should be repaired.

You can ask the system to check the file system at the next reboot by typing

sudo touch /forcefsck

.

Used unetbootin to create a drive and booted my little Win7 PC off it, and was able to select "Ubuntu" from the list of operating systems. It started up what seemed to be normally, then gave me a message along the lines of "No root file system is defined". I can not use Ubuntu because of that error.

Issue #2: When I shut off the desired pc and reboot, the screen to select whether to use Windows or Ubuntu appears, and neither before nor after this screen can I access any boot settings screen. I can also not seem to uninstall the wubi install of Ubuntu.

Essentially, all I need is the Windows 7 wiped, and ubuntu (12.04-15.04, don't care) permanently installed.

What are my steps to correctly do...

Sup. I'm a complete rookie when it comes to Linux.

I just got a Ubuntu 11.10 boot CD (Wubi) and I want to install it on a clean HDD.

I only have that one drive, so I don't want dual boot or anything like that - just an HDD that automatically boots Ubuntu when I turn on the computer.

The problem is that when I boot using the CD, I can't do anything in the setup because the partition list is empty and when I click "Install", it says "No root file system defined" etc.

I was looking for solutions on other sites and saw this:

I don't see those options at all.

The HDD has been cleaned with CCleaner (1 pass) and quick formatted in Windows 7, if that helps. Maybe I'm using the wrong setup CD? I dunno.

Help!

--------------Solutions-------------

I may be wrong here, since I've never used the WUBI version of Ubuntu, but I think it's meant to be installed from inside Windows, just like you'd install a normal Windows app....
