We have had a fair amount of issues relating to Windows 10 and dual-booting.
I believe a lot of trouble comes from using BIOS partition scheme with UEFI and we also say - my self included - the combining BIOS partition scheme with UEFI boot is a no go.
But how true is the statement? I am in a state of confusion right now regarding this issue.
I have been asked to rework a computer to dual boot with Windows 10 / Ubuntu and because Windows 10 needs to be reinstalled and I would have Windows not placing partitions outside a defined size of 64GiB - I have cleaned the disk and used cgdisk to create a GPT partition scheme with a 64GiB partition at the very beginning of the disk and a placeholder partition for the rest.
Now, starting the Windows installation and selecting the 64GiB partition - Windows refuse to install because the partition scheme is GPT.
The system setup in the firmware to boot UEFI and with secure boot disabled.
OK then, let’s tell windows to use a 32GiB partition for install and see what it does.
Reboot into live Manjaro and do a
sudo fdisk -l
Two partitions has been created
- One 549MiB Type HPFS/NTFS/exFAT
- One 31.5G Type FAT16
What? Confused? Indeed I am!

Checking with BIOS - sneaked in CSM boot - disabled - trying again.
It seems disabling secure boot enabled CSM - retry.
