Ubuntu Linux has become one of the most popular of all the Linux distributions.
And through the process of updating a system, you should be able to tell exactly why this is the case. Ubuntu uses two different tools for system update: The Update Manger is a nearly 100% automatic tool.
It detects, but does not add Debian to the grub menu.
I'm finding precisely the same problem when I boot Debian (for which I have to edit the BIOS boot order and choose that hdd). EDIT: And, yes, I have os-prober, and when I run that, it finds Debian, but that doesn't add it to the grub menu, either, or, rather, running that first, and then running grub2-mkconfig, still no difference.
In fact, some distributions are distinctly different down to the type of file types they use for package management.
As you can see there are number of possible systems (and the above list is not even close to being all-inclusive).
For some new users this left their machines outdated or without applications they needed. Now Linux is exponentially more user friendly - to the point where so much is automatic and ¬†that today's Linux hardly resembles yesterday's Linux.
Of course, at the time, most everyone trying their hand at Linux knew they were getting into something that would require some work. But even though Linux has evolved into the user-friendly operating system it is, there are still some systems that are fundamentally different than their Windows counterparts.
Instead you will know updates are available because the Update Manager will open on your desktop (see Figure 1) as soon as the updates depending upon their type: If you want to manually check for updates, you can do this by clicking the Administration sub-menu of the System menu and then selecting the Update Manager entry.
Often people want to use install or update software using the command line. First become root, and then you can use the following commands: And now you can play DVDs!
You can find Totem in the "Applications" menu, under "Sound and Video." It's just called "Movie Player." Sometimes it will say that it can't play a DVD, but it will usually work if you close Totem, then insert the DVD into your drive, then wait for a popup to ask you what you want to do, and then click "Open." (Thanks to Kai Thomsen for the original location of the ATrpms key, and thanks to Tom Householder for the new location!
But you must have all /boot partitions mounted (use "palimpsest" to do this) the ubuntu equivalent for this command is easier : "update-grub" but the fedora grub menu you get looks and is better.jringoot run grub-mkconfig/su grub-mkconfig to update grub so in your case what happened is fedora was installed first, with GRUB 2 installed to the MBR of /dev/sda.
linux mint was installed second, again to MBR, overwriting the previous instance.
So to make the task of covering this topic less epic, I will cover the Ubuntu and Fedora systems.
