Thread: dual booting windows/opensuse

    Default dual booting windows/opensuse

    I'm attempting to install OpenSuse Tumbleweed on a new laptop (Acer Touch 12) with an already existing Windows installation. I had already tried this by going with the installation prompt (auto) but only Windows booted up. Upon further looking online, I understood that I needed to manually partition plus edit the windows boot partition to /boot. So trying it again, my main objective is to delete the partitions the previous install created and replace them with simply "/" and swap. When I got to the expert partition screen I saw a lot of partitions listed and really want to be careful *not* to delete anything windows related. I've included a picture of the the partition list. Noticed I can't do attachments here so here's a link to flickr https://www.flickr.com/gp/rkonrad/537b85

    Which are safe to delete? Thanks!

    You'd better create some free space from Windows. If you want to use btrfs I suggest a minimum of ~60GB. And make sure FastBoot is disabled.

    Hi and welcome to the Forum
    I would suggest also grabbing the live USB of Tumbleweed and booting from that to check all is good with the hardware etc.

    Now unless there is something specific for the windows install, you can download the latest iso image for windows (direct from Microsoft) to re-install, WinX key is stored in the BIOS so will re-activate if you need to re-install (and in WinX case when it upgrades the build it will create yet another small partition).

    Also if booting from the live USB can also post the information about the disk partitioning (lsblk gdisk etc).

    The standard is sda1, type ef00 and around 200MB for /boot/efi (all OSes), sda2, type 0c01 16MB reserved for windows, after that it's what ever you want, I'm sure there is also an Acer image for recovery, those I normally dd to an image stored on an external usb device (never used one yet).

    What went wrong last time was an additional 500M ESP partition was created instead of reusing the existing 100M ESP partition. An unfortunate and misleading message by the installer induces many to make that mistake. While it is technically OK to have a separate ESP for each OS, it requires intervention of the UEFI BIOS each time you wish to boot the other OS than what was booted last.

    No /home partition was created. The prior installation created:
    Code:
    /dev/sda5 500M ESP #2
    /dev/sda6 35G BTRFS
    /dev/sda7 2G swap
    You could delete all those at any time, before or during openSUSE installation. As Knurpht wrote, best place to start is have Windows itself create needed freespace - normally. However, with so small an SSD as you have, both Windows and openSUSE would be crowded by a partition scheme materially different from what is already in place. The only change I suggest to make is to delete sda5 and sda6 and recreate sda5 using the combined space of those two. Then have the installer utilize the EXT4 filesystem type for openSUSE on sda5 instead of BTRFS, which would be troublingly small because of its snapshotting. openSUSE should use the existing /dev/sda1 ESP partition mounted on /boot/efi/. You should ignore the error message about 100M being a too small size.

    In the future, please try to use https://susepaste.org/ for image uploads. The one you created is too small for me to be sure I understood what I was seeing, and very difficult to force to a large enough size to make out anything at all.

    Burn a netinstall image to USB stick and boot from that.

    You may safely delete sda5, sda6 and sda7. Mount sda1 as efi system partition at /boot/efi. Create / and swap as needed.

    When done with the installation you will want to boot opensuse. It has a menu offering Tumbleweed as default and Windows as another option.

    Watch for boot order:

    Code:
    erlangen:~ # efibootmgr -v
    BootCurrent: 0004
    Timeout: 1 seconds
    BootOrder: 0004,0000,0001,0002,0003,0005,000B,000C
