So I have read through articles such as this one, but none that I have read through seem to walk me through a setup that I want, and that I hope is possible without some crazy preparation. The article I mentioned seems to set things up on two hardrives, but doesn't mention if there is already data there that you want to maintain and keep as a shared portion of it.
Right now I run a sole installation of Windows 7. My boot drive right now is a 120GB SSD with about 6GB of free space left. I have a backup drive where I store most of my user data, which is a 2TB HDD that has about 1.77TB of free space left.
I would like to install Ubuntu Linux on my HDD, while leaving Windows 7 on the SSD by itself. However, the SSD does not have enough room to store any user data outside of the Windows installation and a few files here and there, so I would like to maintain all of the data that is currently on the backup drive, and keep a "shared" partition on the HDD of user data that both Windows and Linux can touch.
Is there an easy way that I can install Ubuntu on the HDD while keeping the data that is currently there in place (on a majority of the drive), and just partition only what Ubuntu needs to run smoothly on the rest of it?
Ideally I would then also like to boot from the Ubuntu partition and be given Windows 7 as an alternate bootable option in the GRUB menu, but I've only done this on a single hardrive in the past.
Are there any articles or blog posts about setting something like this up? Or do any of you guys have a set of steps I should follow? I just don't want to screw anything up.
