That’s exactly what can be done for an easy installation. You only need one partition to install Manjaro in BIOS mode. Only, consider using a swap file then later-on.
You should place the bootloader into MBR. After executing
in your freshly installed Manjaro OS you can boot into Windoze from your grub menu. If your grub menu is not appearing you might need to modifiy the /etc/default/grub file a bit, but one step after another, see here:
Thanks for the link, linux-aarhus, but that guide is aimed at UEFI systems…
If I follow the partition instructions, after creating the swap partition, and clicking on ‘Create’ button again, I get the you already have 4 primary partitions message. This message is why I posted my original post…
Also, since I have 8GB RAM, do I really need a swap partition?
So, given situation, I can just create a root partition and call it good, correct?
If I can just use ‘/’ mount point, would I need to check any of the boxes under heading ‘Flags’ ?
Correct - it was initially targeted efi boot but has been amended with info where mbr and uefi differ.
You don’t need to bother with the flags - but for info the flags primarily sets different partition type UUIDs e.g. 0x8304 for x86_64 root and 0x8302 for /home. Those flags make the partitions discoverable by systemd without entries in fstab.
@ArchiMark, don’t follow that link, it’s not much helpful in your case!
Simply, use the manual partitioning mode in Calamares to let it format your / partition and make sure the bootloader is placed in MBR, that’s all what you need to consider. I have done exactly the same when first installing Manjaro as dual boot with Windoze and still use this install.
No, you can use a swap file as indicated already. Not having swap would be possible but not recommendable.
