    Re: problems dualbooting windows 8 and ubuntu

    Your SSD has to be either for Windows or your turn off the Intel SRT and use the SSD for / (root) but then you cannot use it for Windows. Your choice. If you use Windows more then I would keep it for Windows.

    My standard recommendation is 10 to 25GB for / (root). For new users I usually suggest the separate /home as then a new clean install is easier. But more advanced is separate data partitions. But if dual booting with Windows I do suggest that you have a shared NTFS data partition and only set Windows system as read only. And with Windows 8 hibernated (it is always hibernated or SRT), you may not even be able to read it.

    Partitioning is personal and how you use system. I find my own most optimal configuration a year or two later is not so good & time for changes. By then I decide I want a new hopefully more reliabe drive and have space to reorganize.

    I started with just /, swap. I did have XP & shared NTFS data on one drive and Ubuntu on another drive. When I got a new larger drive I created new NTFS shared data and Linux formatted data partitions and lots of 25GB partitions where I install another Ubuntu to test or install another system. I now need to houseclean several version as they are not supported but I still have them. I only have a separate /home for literally one day. I created it for my new upgrade from 32 to 64bit with 9.10, but realized I wanted to share data not user settings.

    I would create a 25GB / partition, and either 4.5 or 2GB for swap. I have 4GB of RAM and do not think I have used my swap. But because I have some swap on every drive except SSD, it automounts all of my swaps so I end up with more than I want unless I manually remove entry from fstab.

    You also do not have to fully partition drive but have to plan ahead a little as reorganizing can be difficult. I usually put swap last, Windows first, then Linux boot partition and then data partition(s). If thinking of other installs I may leave space between last data & start of swap so I can either expand data partition or create another 10 to 25GB partition to experiment with.

    If you have UEFI, you have gpt partitioning. You can only have 128 and they all are the same.
    Only with MBR(msdos) partitioning do you have primary & extended with logical partition in the extended.

    Re: problems dualbooting windows 8 and ubuntu

    what about boot partition? does the installation automatically do it for me or do i need to manually do it?

    ill leave the ssd for windows (i want to get used to using linux but i want to leave it for windows because this is what i use for college and leaving windows will be for that)

    so then correct me if im wrong (im sure im doing it wrong)... i would make a 25bg for /root, 4gb for swap, and the rest for the os? in that order?

    what about making a seperate partition to put my media files in for both os's to use? would that be considered /home?

    ive decided to give each os 100gb including the other partitions needed on both os's and 300 as storage for my movies, photos, etc.

    if im wrong (which i know im missing something to get it how i want), please let me know in what order you would do the partitions, what size, and what type of format...


    EDIT: can you please also explain what each partition is for? some are self explanatory but since im a new linux user id like to know what exactly these partitions are for, thanks!

    With Ubuntu the default install partitions are / (root) and swap. All the system is in folders in root. And that is all you need for a desktop install.
    In the old days or on some servers to isolate activity some or many of the system folders may be installed to separate partitions. Old systems or servers or some with different formats may need a separate /boot partition.

    But if you want to easily reinstall / (root) for a new version separating /home makes that easier. You still should backup /home as it has all your data & user settings, but you can reinstall to / reformat it, but not reformatting /home to preserve data & settings.
    Since /home is Linux, it cannot be NTFS, so you cannot use it for sharing data.
    You need a separate NTFS formatted data partition.

    Swap is used as overflow for RAM or if you launch so many apps at once that all of RAM is used. But Linux caches activity so RAM is often full, but it releases unused apps space for a new active app. Only if all spce is used for active apps then you may need swap.

    /dev/sdd4        28G  4.8G   22G  19% /media/Quantal
    My sdc2 is NTFS from when I still used XP, my sdc6 is ext3, but I would use ext4 if creating it now. And I just have / on my SSD in sdd3. I have another install in sdd4. I am up to 18 partitions in sdc, many obsolete or test installs.

    You can only have 4 primary partitions and one of those needs to be the extended partition. The extended partition acts as a container for all the logical partitions.
