dual booting system


I am a bit confused about a dual booting system. I Already have windows 7 on my computer and wish to install ubuntu 11.04 but I keep reading about Grub 2.
Does grub automatically install with ubuntu or do I need to install it prior to installing ubutu ?

I just did it myself buy downloading a free partitioning software and ran the software in windows.
I used EASEUS free Partition Master. You can use this create a unallocated partition and when you reboot with, lets say Ubuntu live CD, You will be given the option to install along side windows.

You can also use the live CD to manipulate your partitions as well. More detailed info at this site;
https://help.ubuntu.com/community/WindowsDualBoot
I just found it easier, since I already had Windows, to run a partitioning software within windows first.
Be sure to backup all data before any partitioning procedure and if you are already running Windows, Be SURE to defragment first.
If you Google "dual boot windows and Linux" you will find many tutorials that give you step by step instructions.

So once you have defragmented, backed up you data, made you partition and ran the live CD, their will be an option to install beside Windows.
Install will do everything for you to dual boot.

Hope this helps

I'd suggest that you do not dual boot.

If you have a new system you can easily install a free virtual machine to run both windows and almost any number of OS's safely, easily and without any danger of wrecking your windows install or it's recovery data.

Yes, Grub automatically installs with Ubuntu. It installs with most other Distros too.

Play Bonny!

This sounds like an excellent idea but why would anyone want to use a dual booting system if they can use this virtual machine ?
I am tempted to wipe my drive and start from scratch, installing virtual machine, then windows 7 then a couple of Linux programs.
Is it that simple or am I missing something ?

There are advantages and disadvantes to both approached. Virtual machines run on virtualized hardware, how the hardware is virtualized and how much of it is virtualized is an issue of Paravirtualization vs Full Virtualization, generally speaking Paravirtualization is better but may not be possible.

Advantages of VMs
- you can run them at the same time as the host OS/Hypervisor
- You can switch between them at a moments notice
- It is easier to back-up and restore VMs then entire machines

Disadvantages
- VMs lack direct access to hardware (lower performance/Somethings occassionally require direct access to certain types of hardware EG Games requiring GPU Access)
- You MUST be running the host OS/Hypervisor to run any VM(more resources required/lower performance)

You will need a VM manager/Hypervisor if you wish to go down the VM route. I personally have used several different such programs and hypervisors in the past and they all have pros/cons. VMWare Player I think has been my favorite for the home.

Advantages of Dual Booting
- Dedicated use of hardware (higher performance)

Disadvantages
- You have to split Partitions up, Mess around with the MBR, Ectera.

r3sistance posts good points but my opinion was more directed towards what a newbie ought to consider more based on two issues. One is ease while the other is data security. It is well known on linux forums that someone will bork their host system and post a question how to fix it. I have done it many a time long ago.

A VM is a real easy way. Most new systems can run a VM client OS near, at or above native speeds. I feel it is really suited for newbies and people like me that just want stuff to work as fast and as easy as possible.

With the ease with which Ubuntu installs now, I think it is safe to do a dual boot with it. I think the only thing to keep in mind is to not try to partition the drive using GParted (I have not tried such a thing after being free from Windows for three years, but back then it was a bad idea - don't know if GParted can handle the C: drive now). If one partitions the drive using the Disk manager in Vista/7 itself, then there is virtually no chance that the Windows install will be borked.

The reason I am advocating this is because when I first installed Ubuntu, I tried out many other GNU/Linux flavors by installing in VMs. However, it became very clear that I could never have the true experience of things unless I did the full install. I now maintain a quintuple boot system, and I love every moment of it! If one wants to experience the true power of a flavor, one is better off dual booting; if one just needs to run a few programs and use Windows most of the time, maybe Cygwin is smaller and simpler (though I loathe such a thought... I did once try out Cygwin when I still had Windows, and I found myself that I was expanding it more and more in the hope of trying to become a full-fledged system in itself... That was when I installed Debian Etch alongside, and here I am now...)

Maybe use virtualisation to do a bit of distro-hopping 'til you find the distro that suits you best, then dual-boot with it?
