Ubuntu 9.04 Installation Questions

Aug 26, 2009 2:54PM PDT

I am trying to install Ubuntu 9.04 on a seperate partition on my computer. I have Windows XP on my primary partition. I made a seperate 15 gb partition for Ubuntu. It is formated to Fat32 now but I am not sure if that is the best for Ubuntu. What file system should I use for Ubuntu? Also when I select the partition in the Ubuntu installer it says that "The root file system can not be found. Please fix this from the partition manager." What is it doing and how can I fix it?

Thanks!!!

What works better.

Is to not format such partitions. Instead we leave space "unpartitioned" and let Ubuntu find and use that.

When installing Ubuntu, you should be able to choose the partition to install on.

What I would do is in the Ubuntu partition manager (During installation, you will have to say you want to partition it manually).

Select the 15gb Partition, delete it (Wait until it has refreshed and now displays 15gb unpartitioned)

Then, from this space, create a new partition, say ext-3 (file system).

There should be a box to enter information in, called "Mount".
For this, type "/" (Forward Slash, this defines this partition as root)

You may also want to create a small swap drive, helps with the performance I think.

Good luck.

Not clear
Aug 28, 2009 4:50PM PDT

as what is that you want. You have installed Ubuntu, and I presume that you will be using both Win XP and Ubuntu. The screen gives this option.

You can change the default OS by editing the menu file in Ubuntu. Is this what you want?

Sorry for the break.

Not too sure if the type of start screen you want is possible without playing around with the Menu listing file of Ubuntu. The screen that you want comes up after the initial Windows boot.

You can edit the screen display so that it shows simply a choice of Ubuntu or Windows.

Yes

That is what I am looking for. How do you do that.

Also, is there any way to have the OS select screen pop up only when a selected key is pressed at start up?

Editing menu.lst
Sep 1, 2009 7:15PM PDT

1. Boot up the computer in Ubuntu

2. Backup the menu.lst file:
a) Applications > Accessories > Terminal
b) Type "sudo cp /boot/grub/menu.lst /boot/grub/menubak.lst" and Enter
3. Edit the menu.lst file:
a) Type in Terminal "sudo gedit /boot/grub/menu.lst" and Enter
This will open the menu.lst file in the editor

locate this:

In your case, only the first 2 title blocks are necessary.
Ensure that ALL lines including "Ubuntu 9.04, kernel 2.6.28-11-generic (recovery mode)" is deleted.

On line 14 you have a statememt "default 0"

If you want the Default system to Bootup as XP, leave it as it is. If you want Ubuntu as the Default bootup, change it to 1.

Save and Reboot.

My advice would be to delete all lines after "### END DEBIAN AUTOMAGIC KERNELS LIST" so that the option of Repairing the Ubuntu OS is available.

Great!

Thanks that worked perfectly.

Also do you know of any way to have that screen pop-up when a hot key is pressed? If the hotkey isn't pressed on startup it will just default to windows XP.

Default line says which option is default start to count from 0, 0 means first. Timeout says how long grub will wait until entering default in seconds. hiddenmenu hides menu unless esc pressed.
Linux users who do not have options in grub may want add to menu.lst:

hiddenmenu
default 0
timeout 0

This is an easier way

You can install Startup Manager Via Synaptic Package Manager. This gives you a GUI panel to edit GRUB.

hmmm

I prefer clasic way: edit configuration text files. This is easy too: you can keep notes, old settings with # at start of line etc.
