When I installed Manjaro, I gave it 100 GiB to work with. I then split 90 GiB for the main installation of Manjaro, 9.8 GiB for a swap partition, and the rest towards an EFI partition. While the installation is succesful, and I am able to boot into it manually, the computer will still attempt to default boot into Windows. I suspect it may be due to the EFI partition of Windows that has not been replaced, therefore the Manjaro EFI won't boot default unless I specifically select it in the Boot-Options.
If I simply delete the Windows EFI partition, would Manjaro default boot? Would that potentially break GRUB booting to Windows, or would I still be able to access Windows through the GRUB bootloader?
Additionally, if possible, how can I hide the EFI partition from being shown in Dolphin?
