    I have installed Windows Server 2008 on a logical, but there was also a
    Windows 7 install that had a small boot partition as well.

    I am having problems with this parted magic. I've written it on my USB and tried booting from it. But everytime I turn on the power of my laptop, after changing the boot priority, it always starts normally. I do not know what's the problem.

    What I did is I turn on the computer, pressed F2 upon startup. Then change the boot priority. I even placed the 3 USBs indicated on the list because I don't know what to choose. (http://azbooki.ru/wp-content/uploads...rviceGuide.pdf page 32)

    Am I doing the right thing?

    You can't just copy the iso to the device you need to dd it or to be sure you need to follow instruction on the site to get a proper boot image to the USB stick.

    Which restrictions?. You can get 50 Linux distros (or more) installed and booting on this hard disk. The only restriction is that you propably won't have time to install them and play with them. The number of logical partitions you can create with MBR partitioning is unlimited. The number of kernel devices used to be limited by the old SCSI and PATA drivers, but it's a different problem*. With GPT, you can have 128 partitions. They are all primary partitions. Thus, in theory, you can install more OSes on a single MBR partitioned disk than on a GPT disk, where you won't get more than 127 OSes (1 partition being needed for the ESP) or rather 126 if you exclude the swap partition.

    * I don't know what's udev limitation. It probably has some (in major an minor disk node numbers). So it's probably still possible to create more partitions than you could actually see... but I don't think we're going to try.

    Actually any distro with Gparted on it will do the partitioning. Linux Mint is one example. It might be easier for you to figure.... Unetbootin and all that....

    Mike, as please_try_again says, having two Linux installs on your system is not only possible but your setup could accommodate more. I always have at least two installs (one for serious things, another for tinkering around). You can stick any Linux distro on a logical partition so long as you can boot via MBR. In accordance to the advice from SDBartitioning - openSUSE (near bottom) I have a separate primary bartition for a /boot/ but I don't know how essential this is to be honest. If you need to move around partitions, you can do using either Windows's DISKPART utility, or Gparted ( although openSUSE Wiki's SDB link http://en.opensuse.org/SDB:Gparted seems to be broken ).

    1. In order to shrink your partitions, you can use the windows partitioner.
    Like described on the page the link to which you gave in your 1st posting.
    It would probably be helpful to defragment your existing partitions beforehand.

    2. The .iso image of Parted Magic represents a bootable live CD, like the .iso image of openSUSE KDE Live CD does,
    which, besides, you may as well use for installation of openSUSE, if you are connected to the internet at reasonable
    bandwidth (at least 0.5 to 1 Mbit/s would be good) !

    You may perhaps have difficulties to understand this hint

    Translating that for you I would write:
    In order to get Parted Magic booting, you as well have to follow one of the procedures described on page
    https://en.opensuse.org/SDB:Live_USB_stick

    In order to get it all running and installed, you anyway need to get practice on how to boot from an USB stick,
    or at least a CD or DVD drive.

    And as proposed by caf4926 earlier:
    Do it, download an openSUSE Live CD through www.opensuse.org,
    burn to a CD or transfer it to an USB stick,
    boot from it and have a look.
    This won't change your system at all, until you eventully decide to push the button and install.

    I suggest you use the openSUSE KDE Live CD, with which you, being used to windows, probably will feel more familiar with,
    and which I like most ... :-)
    If you don't intend to have more physical RAM than 2 MB in your laptop, and as you're not UEFI-booting,
    even the 32 bit version of openSUSE will do.

    And, the openSUSE Live CD's are like quite comfortable rescue systems for openSUSE !
    You'll probably have your recovery/rescue CD for windows as well, don't you?

    Good luck
    Mike

    The OP does not seem to have an UEFI BIOS, and has a pre-installed windows 7 on a 320GB HDD whichthis thread he wants to keep,
    so a GPT isn't a real topic here

    Hi flymail,

    Be assured that I quite well knew what I did, and why.

    Trying to install openSUSE 11.4 with a 1st configuration of my quite new PC where windows 7 occupied about the first 1.5 TB of HDD space
    I once got the warning message
    Code:
    The bootloader is installed on a partition that does not lie entirely below 128 GB.
    see posting #1 in this thread of this forum.

    Despite some in this forum later on stated, that this would be a warning message relevant only to quite old hardware, and that it can be ignored,
    as described in the same posting in the same thread, my system just failed to boot openSUSE from hard disk !

    After making a guided tour around UEFI booting openSUSE and windows 7 with please_try_again then (same thread),
    I finally took the decision to return to a conventional MBR setup for my internal hard disk,
    because windows 7 wouldn't install with a GPT. Period.

    Because I was in the lucky situation that I had a real windows 7 installer disk instead of just a recovery CD,
    I allocated the extended partition as the second partition, right after the small "system-reserved" partition necessary for windows 7,
    see my partition setup as posted above.
    This made it possible to have all root partitions and swap below 128 GB.

    This may have been resolved in openSUSE 12.1, but I didn't check that then.

    Besides, I don't even use yet the 2nd set of logical drives earmarked for Linux distros.
    Probably I'll install openSUSE 12.3 on it, when that gets finished off.

    Yours
    Mike

    In my experience that warning is virtually always a guarantee that the system won't boot after installation.

    TBH, I find It's an issue that's conveniently `swept under the carpet' by installation guides. I hoped the problem would go away with GRUB2. It didn't. If that warning is supposed be relevant for only `quite old hardware' than by `old', the people giving you advice must be referring to hardware built in 2011, because I've regularly seen boot failures after such warnings have been issued.

    Sounds like a sensible solution. I find that dual-systems are most easily managed from scratch (so long as you have all the relevant installation CD/DVDs to hand). I remove all partitions and start again: two primary partitions and one extended. The first primary is /boot/, the second primary is Windows (if I want it), and I divide the extended partition into at least five more logical partitions (Windows' page (D:/), a common NTFS partition for data (E:/), / (i.e. slash), /swap/, /home/ (with symbolic links to E:/).

    Nowadays on desktops, I just find it a lot easier to install a second hard drive for dual-boots, physically partitioning Windows and Linux. Unfortunately this isn't a solution for laptops where the situation is often made worse by not having a Windows Installation DVD to hand because they've shoved a recovery image on the first 10GB of your hard drive as a primary partition!
