Hi everyone. I know this is a familiar looking question, but please hear me out.

I want to dual boot Fedora 15 with Ubuntu 11.04 (to try out GNOME Shell whilst not breaking Unity, which I quite like). As it's mostly to just to try out, I'll probably want to remove Fedora and go back to just Ubuntu, so I wan to ask how to remove the Fedora partition without doing any damage, and how to remove it from the GRUB menu at boot.

Thanks in advance.

Get your partition information with fdisk in Ubuntu. Make a note of it so you know where your Ubuntu partitions are and you don't overwrite them. When you install Fedora, I believe the default will be to create a separate boot partition which you won't need. Read everything carefully during the installation before clicking Next and if you don't understand, stop. The two things you need to avoid are overwriting your Ubuntu partition and making sure you install Grub to the Fedora partition. You will need to run update-grub from Ubuntu after the install. Without more details on your drives/partitions there's not much more anyone can tell you.

if you just want to try it out, why not use a it in a virtual machine? its easy and safe.

True! Why not just use a virtual machine and save your self all the time. As a matter of fact once you try Fedora you wont o back......:-)

There are several reasons why not to try it out in a virtual machine:
1. To test compatibility with your hardware.
2. To get the maximum speed.
3. If you need to run programs that heavily depend on 3D acceleration.
4. If your CPU does not support hardware virtualization.

But if you just want to see how it looks I also would recommend a virtual machine.

Beetle,

To remove the selection from Grub, go into /boot/Grub/grub.conf and edit that little puppy. It's obvious once you get there. Let me know how it works out, yo.

Hey everyone. Sorry I haven't replied sooner, but I've been suddenly busy and haven't had a chance to try anything out yet. Thanks to everyone who's replied so far.

My old computer wasn't brilliant with virtual machines. I tried installing a full distro and found it was unacceptably slow. I'll give it another shot on my newer computer which (I think) has the necessary processor components for virtualisation (it's an Intel Core i3 550). I'm a wee bit concerned about graphics. The computer only has an integrated Intel chip, and I want to check out GNOME 3 with the full graphical effects

Any advice greatly appreciated as always.
