Thread: Installing and partitions

  1. #1

    Default Installing and partitions

    Hello all
    I am almost 100% sure that my question has an answer somewhere on this site but I couldn't find it so...

    I want to install opensuse on my computer that has Windows installed (I can't remove windows[because my father is using it :@]) so I have to resize my partition... I started the instalation and when I got to the Disk step it showed me 2 red line (which as I read mean deleting) and 3 whit lines. So

    I aborted and switch to windows to ask for some help because I don't want to mess up my system.

    I saw that I can resize but I was a bit confused and didn't want to take the risk.
    So can you tell me what should I do to install openSUSE on a 10 gb partition when:
    Current partitions are
    50GB Disk C(Windows) >> 30 Free
    100GB Disk D (stuff) >> 35 Free
    (I think 10GB is enough for learning open suse)

    Thanks in advance

    Note JUST before installing, you MUST defrag Windows.

    Do you have access to a digital camera? I recommend next time you go for the install, when you get to the partitioning section, take a pix with the digital camera, and then post the image on an image paste site such as ImageBam - Fast, Free Image Hosting and Photo Sharing , and post the Link here, and ask for comments.

    Note that a hard drive will allow a maximum of 4 primary partitions. Typically, an MS-Windows operating system should be in one of the first 3 primary partitions (usually the first). Often the 4th primary partition is an "extended" partition, where one can put many "logical" partitions in this "extended" partition. Linux will use both the primary partition and/or the logical partition as appropriate. MS-Windows typically wants to be in a primary partition.

    Also note that the convention in Linux is to label hard drives as hda ( hard drive a ) or hdb ( hard drive b ), etc .... and partitions inside the hard drive "a" as hda1, hda2, hda3, ... etc ...

    Starting with openSUSE-10.3 (I think) a new package known as libata was used, where the names for hda, hdb, hdc ... etc ... were changed to sda, sdb, sdc ... etc (ie change "h" to "s" ) .

    Hence reference your:
    Code:
    50GB Disk C(Windows) >> 30 Free
    100GB Disk D (stuff) >> 35 Free
    its possible that Windows OS is sda1 and the "stuff" is either sdb1 (if a separate drive) or sda2 (if a separate partition).

    openSUSE Linux will want to create 3 partitions for itself. One for a swap partition (very small - approximately equal to, or possibly double your PC's RAM memory size), one for the / (root) partition where all the executables and libraries reside, and one for the /home where all the user data and user configuration information resides.

    For example, you might see proposal for a:
    /sda1 - windows c:
    /sda2 - stuff
    /sda4 - extended *
    /sda5 - swap
    /sda6 - /
    /sda7 - /home
    where the /sda4 might be the active partition.

    But you need to give us that pix from your camera so we can do a quality check.

    I suspect now, when your PC boots, the BIOS after it completes its tasks, then goes to the hard drive master boot record (MBR) which then directs execution to the C: (sda1) drive, which is likely the active partition.

    openSUSE Linux will install a boot manager so that your PC gives you a choice to boot either Windoze or Linux and to do so, it will modify the MBR.

    Most the time, IF things go well, openSUSE will replace the Windows code on the windows C: (sda) hard drive partition's Master Boot Record (mbr) with generic mbr code, pointing to a Linux partition, where that Linux partition will be the active partition. That Linux partition will then allow the grub boot manager to run and give you a choice to boot Windows or Linux. This should all go automatic, but to be doubly sure, you could also take a pix of that grub boot proposal with your digital camera, and post that here also.

    I'm no expert in this (others know a LOT more than I) but if you defrag before hand, and IF you have your father's permission, this should go well. Ensure all important data of your father's is backed up first. That is very important.

    Here are some photos:
    WHen I see it know (and look carefuly) I think all is OK

    The Wizard is thinking properly. Shrink, create 3 partitions, set maunt poit... But I want to see that you aprove it before I continue.

    It looks ok. Its taking space from /dev/sda5, which appears to be a logical partition inside of an extended partition. I suspect /dev/sda5 is the "stuff" D: partition you referred to.

    It recognizes your
    • /dev/sda1 is your MS-Windows OS and it will be mounted as /windows/C
    • /dev/sda4 - not mentioned - but I think it is there and it is your extended
    • /dev/sda5 was likely your windows D: drive, it is being reduced to 77GB from the 100GB previously mentioned. It does not appear that it will be mounted. You may wish (after a successful install) to set up a mount point for it under /windows/D
    • /dev/sda6 - this is a 2GB swap drive
    • /dev/sda7 - this is the " / " (root) where the programs and libraries and system files will go. Its only 8.8 GB in size, so do not go hog wild installing too many programs ...
    • /dev/sda8 - this is the /home. This is where the user's data/configuration stuff will reside, and its where you should be spending most of your time.
    So yes, it looks ok to me.

    Be certain you defragged D: before this.

    Its too bad you did not provide the grub boot manager info.

    I actually don't know what this is and where I can find it...
    I just insert the cd and restart it boots automaticaly and the instalation screen appears. If you explain where can I find it I can take a pic.

    CD ? or DVD ? I think those images come from an installation DVD ? or do I have that wrong ?

    So you gave me a pix of step-6:
    Installation/11.1 DVD Install - openSUSE

    If you look at the second image in step-7, (Installation settings) you will see a "booting" section. I'm curious about that:
    Installation/11.1 DVD Install - openSUSE

    Have you looked at this guide:
    NEWBIES - Suse-11.1 Pre-installation PLEASE READ - openSUSE Forums

    Oh I aborted before that step
    I will post a photo tomorrow becuase I have some work and it's getting late here. And I will defrag tommorow also so I will be ready for the install.

And it is planning to make sda2 the active partition. Which means after the install is complete, when the PC boots, the BIOS will go to sda2 (and NOT to windows sda1) and from sda2 it will be directed to the file /boot/grub/menu.lst on sda7, where that "menu.lst" file provides the option for your PC to boot to either:
    • Windows C: (sda1) or
    • SuSE Linux (sda7) or
    • SuSE Linux safe settings (sda7) - identical to the above regular settings, but it has a bunch of boot options. Its used for emergencies when the above does not work.

    Needless to say, this menu.lst file is an important file. I always back it up. That backup can be done some time (a week or so) after the install is complete.

    Hence, to change my post above, I believe the openSUSE installer will designate:
    • /dev/sda1 - is your MS-Windows OS and it will be mounted as /windows/C
    • /dev/sda2 - it is your extended partition
    • /dev/sda5 - is likely your windows D: drive, it is being reduced to 77GB from the 100GB previously mentioned. It is a logical partition inside the extended. It does not appear that it will be mounted. You may wish (after a successful install) to set up a mount point for it under /windows/D
    • /dev/sda6 - this is a 2GB swap drive. It is a logical partition inside the extended.
    • /dev/sda7 - this is the " / " (root) where the programs and libraries and system files will go. Its only 8.8 GB in size, so do not go hog wild installing too many programs ... It is a logical partition inside the extended.
    • /dev/sda8 - this is the /home. This is where the user's data/configuration stuff will reside, and its where you should be spending most of your time. It is a logical partition inside the extended.


    I do not believe you will be able to see the D: drive after you boot to Linux. Windows will see it. (although from Linux it may be mounted as /windows/D and its just now shown by the installer). No worries, as openSUSE can be "tuned" later to add the D: drive as /windows/D. Also, after installation is complete, you may have difficulty read/writing to /windows/C (the C: drive) and if so, post here and one of our users can explain the easy fix to that.

    Reference software being installed, you could also consider removing all "beagle" applications. Beagle will slow down the PC incredibly. Also , in a later menu you will be given the option to disable ipv6. Do disable it. ipv6 may slow the PC Internet access down incredibly.

    So that looks ok. Good luck.

    When I installed openSUSE-11.1 I choose "OTHER" and selected KDE3 which is more stable. If its not too late to go back, I would recommend you go back and select "OTHER" and "KDE3" for your desktop.
