    Default Looking for advice on installing on UEFI desktop

    I purchased a new desktop PC , as documented in this thread: https://forums.opensuse.org/showthre...light=hardware

    I'm looking for opinions on how to install an OS on this PC if UEFI/GPT is selected ?

    The PC comes with a 2 TB hard drive, and a 256 GB SSD drive, and without an operating system installed (at my request). The motherboard is a Gigabyte Z87X-D3H which supports UEFI.

    I'm thinking of puting on the 256GB SSD drive the following;

    • freedos - which may be possible per : https://lists.gnu.org/archive/html/h.../msg00047.html
    • windows7 - it appears this may need to go on first , albeit I would prefer to install it later
    • openSUSE-13.1 ( / root partition)
    • openSUSE-TBD (some TBD milestone/beta release)
    • swap


    The 2 TB HD drive I plan to carve up into a couple of partitions to hold the /home (ie the data) for the openSUSE installs. I could also put partitions such as /var and /tmp on the 2 TB HD as part of an effort to reduce wear and tear on the SSD drive.

    My research into Windows7 failed to give me one case of where a PC with only GNU/Linux only in a UEFI/GPT setup (but with empty drive space/partition) had windows7 installed later. Every guide I found had Windows7 installed BEFORE openSUSE. I don't have Windows7 currently, and it may take a week or two to obtain in an inexpensive OEM version to install. Hence I would prefer to install it later, but this appears frought with risk/uncertainty (and hence Windows7 must be installed first). Opinions?

    Free Dos - has anyone actually succeeded in putting freedos on a UEFI/GPT system ?

    My SSD drive, although it has no partitions, is flagged as MBR. I'm I correct this is a simple matter to reflag it as GPT ?

    Here is some detail on the hardware (obtained by booting to a liveDVD) :


    and from fdisk -l
    Code:
    linux:/home/linux # fdisk -l
    
    Disk /dev/sdb: 256.1 GB, 256060514304 bytes, 500118192 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes

    Sector size (logical/physical): 512 bytes / 4096 bytes
    I/O size (minimum/optimal): 4096 bytes / 4096 bytes
    I was curious if these were setup for gpt, so I tried gdisk:

    First the hard drive:
    Code:
    linux:/home/linux # gdisk -l /dev/sda
    GPT fdisk (gdisk) version 0.8.7
    
    Partition table scan:
      MBR: not present
      BSD: not present
      APM: not present
      GPT: not present
    
    Creating new GPT entries.
    Disk /dev/sda: 3907029168 sectors, 1.8 TiB
    Logical sector size: 512 bytes
    Disk identifier (GUID): 1E15EA18-90C0-419B-B2F6-DDF9EF154E9C
    Partition table holds up to 128 entries
    First usable sector is 34, last usable sector is 3907029134
    Partitions will be aligned on 2048-sector boundaries
    Total free space is 3907029101 sectors (1.8 TiB)
    
    Number  Start (sector)    End (sector)  Size       Code  Name
    and then the SSD drive:
    Code:
    linux:/home/linux # gdisk -l /dev/sdb
    GPT fdisk (gdisk) version 0.8.7
    
    Partition table scan:
      MBR: MBR only
      BSD: not present
      APM: not present
      GPT: not present

    I booted the PC to a gparted liveCD and it appears it will be easy to change the SSD to a GPT ... I note this:

    and for the interested, this is what I see on the 2 TB hard drive:

    So I think I now need to decide if I carve up the HD/SSD the way I want and then install openSUSE now, or if I wait until I have Windows7, install that, and only then install openSUSE. ... < thinking > ... I still have not decided if I want to put Windows7 on this PC. For certain openSUSE is going on the PC.

    How about if you were to install openSUSE now.

    Then, if and when you decide to put W7 on it, you back up all your system first.

    After W7 is on, if you can't get things to work properly in short order, follow up with another -- but basic -- install of openSUSE, then restore your root and home partitions from the backup of your working system?

    <thinking too>

    Hi oldcpu !

    Sorry, I missed your previous thread.

    Just only checked the first few lines of your posting,
    and ... me personally, I do see a problem with windows 7
    (not with openSUSE).

    Not too long ago I assembled a PC my own,
    using a motherboard capable of UEFI booting.

    I just couldn't get windows 7 install on a GPT partition.

    And when - at least - I finally got windows 7 installing in UEFI mode,
    by the help of please_try_again,
    windows 7 created some weird kind of partition table.

    The thread is
    http://forums.opensuse.org/showthrea...os#post2463057
    don't put it aside just because oS11.4 appears in the title - I finally installed oS (openSUSE) 12.1.

    Since your hard disk has only 2TB size (like my hard disk),
    you probably could as well still format it using an MBR partition table.
    For example:

    (1) primary partition - microsoft reserved - created by win 7, which probably should be installed first
    (2) win 7 (NTFS) "drive" C:
    (3) freedos
    (4) extended partition for
    - openSUSE partitions (swap, perhaps two / or root as logical "drives" in the first part of this extended partition, and two /home after that)
    - a possible NTFS "drive" D: for windows and data exchange.

    However, if your hard disk has physical sectors/blocks of size 4096 instead of 512 bytes then you may have a problem.

    Otherwise not.
    Booting openSUSE, you should further still be able to use additional hard disks with more than 2 TB size that have a GPT - at least as far as I read.

    Good luck !

    This should read:

    I just couldn't get windows 7 installed on a drive with a GPT partition table.

    Further thoughts

    Where is the need to do this ?
    Leave it as it is, i.e. use MBR for it.

    Yes, you are at a different starting point than I was, because you have two drives - the SSD and the hard disk
    (I only had and still have one hard disk).
    I didn't take that into account in my posting above.

    If you don't want to use the SSD as a cache, but as a separate drive,
    then you probaly would like to boot openSUSE from the SSD,
    to speed up booting.

    freedos would probably like to boot from that SSD in non-UEFI mode as well
    (i.e. booting from a hard disk/SSD with MBR).

    And windows 7 doesn't even seem to have the capability to secure-boot
    (which would require UEFI-booting).

    You may end up with an MBR for your SSD and a GPT for your hard disk.

    But I have no idea if windows 7 will support this,
    if any "drive" like D: is to be placed on the hard disk when this one has a GPT.

    Good luck !
    Mike

    Yes, that is in fact why I limited myself to a 2 TB hard drive. I wanted a backup option of adopting an MBR approach. I know how to easily install GNU/Linux on an MBR system, and then later install MS-Windows-7.

    But I would like to learn about UEFI/GPT, and one way to do it, is to put same on one's PC. Hence my being tempted to go for the challenge of a UEFI/MBR approach.

    I thought about this but when I surfed to try and find proof that one could mix MBR and GPT with one operating system, I had no success in obtaining successful examples (only posts of users with trouble and no solutions).

    Understand. I recall that thread of yours.

    Having typed that, I also note there are videos on youtube showing cases of users who succeeded , and they give step by step guidance in the video. But in all cases, they started with a clean unpartitioned hard drive.

    I am very tempted to do that.
