    That is the ms reserved partition which does not have a format so gparted will not parse it, but it is ok. Windows has to have space to store serial numbers, DRM license info, and some virus checkers may use it.

    Are you booting in UEFI mode? Ubuntu should offer just to install to unallocated space or let you manually partition if you want a separate /home.

    Re: Unbuntu 12.10 Installer doesn't see windows partition.

    I'm getting this screen when I choose to boot into LiveUSB in UEFI, so I'm pretty sure it's loading in UEFI.


    I choose to try ubuntu and from there I attempt to install. If I choose "something else" what are the steps I should take to get it to dual boot?

    See post #5.

    If you just do the default install it will only give you / (root) and swap. Better to use Something Else or manual install and choose a smaller / of 25GB and separate /home or data partition(s). You then do have to choose partition size, format (ext4), and mount like /, /home or other. You do not need other system partition for most desktop installs, but may want data partitions. If dual booting with Windows also create a shared NTFS data partition. I think the installer now allows that, it did not have the NTFS driver until after the install, so you used to just leave unallocated and create it later (or before hand).

    Re: Unbuntu 12.10 Installer doesn't see windows partition.

    K... I am going to want to use my external hard drive for all my stored data so I don't think it will benefit me to separate my root and home. However, how large should I create my swap? I have 8gigs of RAM, and NixiePixel says I'll need twice the size of my RAM. Do I really need 16gigs of space? And what should happen If I add/upgrade my ram?

    Even so... before I do this I want to clarify my plan with you.

    Run the installer from my LiveUSB.
    Choose 'somthing else' when prompted.
    Create a logical partition for the swap (however large you think it should be)
    Create a primary partition for (/) and use the rest of the space.
    Then install ubuntu on (/).

    From what you know of my situation. Do you think this will achieve a dual boot? Or have I skipped a step?

    Re: Unbuntu 12.10 Installer doesn't see windows partition.

    I would still create a / (root) of 25GB and separate /home for the rest of the space you want for Ubuntu.

    The old rule of 2X RAM was when RAM was only 256K or 512K. Once you get over 2GB you will not use swap much. And with 8GB you may never use swap. You would have to load every program and edit large videos all at the same time to need swap. But if you hibernate then you need to be able to save all of RAM into swap (again only if you have filled RAM) or it needs to be the same size as RAM in GiB not GB.
    I suggest 2GB for swap if not hibernating. And with Linux it boots pretty fast so hibernating does not add much.

    Okay then, that leaves me with a 3gig home folder but oh well. I'm installing now. Hope this works! *fingers crossed*

    I might shrink /home a bit and save the space for future use, but that is up to you.

    I installed a new 650GB drive several years ago. I put 2 100GB data partitions and have not filled those. I left most of the rest of drive unallocated and started adding 25GB / (root) partitions for testing or betas. I now have too many.

    Well that didn't work mostly.

    So no dual boot first off. Then I tried to get my dual monitors to run which blanked out the screens. Rebooted and now no desktop or anything. Sheesh. I'm thinking reinstall first off... Then what?

    You think I should shrink /home? 3 gigs is pretty small I'd think. but then again I'm not sure what I'd save their to begin with.

    I mis-read your 3GB /home. If it is that small it is better just to leave it inside / (root). So both can share the same unused space.
    I find the hidden user settings for /home take less than 500MB, but as soon as you start saving anything it can fill quickly.

    I do not know multiple monitors but have seen several posts where users had issues. Depends on your video card and you may have to edit xorg. But some like to push the limits.
