• Dual boot partition help


    I have partitioned my drive as below within Windows 10.

    The guide to dual booting says I should have a fat32 edit boot partition to edit to add a mount point of boot/efi

    I don’t.

    What do I do?

    I am just trying to get a partition for Windows (sda2) a big ntfs partition for files (sda3) and then antergos on another partition.

    How do I achieve this?

    I also get a message about only being allowed 4 primary partitions, am I safe to extend for the home/swap/root

  • You can add more partitions if you create a extended partition first and then all other inside this one.

    On this fat32 EFI partition: only on EFI systems, may you have an legacy BIOS system, or EFI with legacy enabled.

    On BIOS systems grub will be installed inside MBR of the disk, and no extra partition is nedded.

  • Do exactly what do I need to create here, simply 1 extended partition containing the root and swap partitions?

    Will I then get the selection between os on boot?

  • yes exactly, grub menu will be aviable with both OS, if it detects windows right, if not it is simple to add after first boot to Antergos.

  • swap with the size of installed RAM on your system. Rest for root (/) and if you want you can take 30GB for root and the rest as /home to make it more easy, in case you need to reinstall Antergos.

  • @daveydoodle
    You seem to have a non-UEFI system, aka legacy BIOS system. In that system you do not have nor need any /boot/efi partition.

    So in that case the dual booting should be quite easy to do.

    Just install Antergos to the available space. Since the space is the last primary partition, you may need to use it as several logical partitions, if you want to use several partitions for Antergos.

    Antergos can be installed to only one partition (marked as root (/)). That partition can also have a /home folder and a swap file (instead of a swap partition). But if you want to have a separate /home partition and/or swap partition, just use logical partitions.

    Your grub will be installed to /dev/sda. Note that it will overwrite your MBR (what Windows uses for booting in your system), so I recommend you create a Windows rescue disk before installing Antergos, just in case of any problems.

  • Oh I’m such a slow writer… 😉

  • Thanks all for your help, so just to clarify I can just create one new ext4 partition for antergos with a mount point of /.

    I don’t need a separate partition for swap/home if I don’t want separate partitions?

  • @daveydoodle That’s right. But please create the Windows rescue disk, and make backups, both before installing Antergos. 🙂

  • @manuel but you are adding more information, thats never bad 🙂

  • Hi, unfortunately I have tried the above and now after installing antergos my PC just displays the text ‘no operating system’. What to do?

  • @daveydoodle
    Well, what did you do?
    How did you create the installer stick?
    How did you choose partitioning?
    Did you select to install grub to /dev/sda disk?

    The message sounds like you didn’t install grub, or there was a problem with it.
    Can you show a picture of your partitions?

  • The install stick was made using Rufus in Windows in DD mode, it went through the installation fine.

    Partitions attached. I didnt do anything regarding grub, I just made the partitions as suggested above.

    If I insert the usb stick back in it will boot into the installer again.

  • @daveydoodle You deleted your large Windows partition and installed Antergos in its place. And you have no grub installed?
    You can install grub to /dev/sda using terminal command arch-chroot. So boot with the stick, command
    sudo mount /dev/sda3 /mnt
    arch-chroot /mnt
    grub-install /dev/sda
    grub-mkconfig -o /boot/grub/grub.cfg
    exit
    umount /mnt
    reboot

  • Sorry, use word sudo in front of all commands above.
    I put it only to the first.

  • Hi,

    The smaller 115gb partition was Windows, however i’ve just decided to do a completely standalone Antergos install, i’m just going to use a KVM to access my windows desktop instead.

  • @daveydoodle Alright, that is probably a bit easier. Good luck! 🙂
