Bootloader installation fails while installing the system as dualboot on separate disks

General system EndeavourOS installation
1

Hi,

I’m trying to dualboot endeavour with windows on separate disks but the installer returns an error during the bootloader installation.
I want the bootloader to be on the same drive as windows so that it shows up automatically when turning on the computer. I managed to successfully install endeavour with the bootloader on the same drive as the OS but that causes it not to show up on startup and turn on windows automatically (I have to press F11 and choose the correct disk to access endeavour).
Here is a link to the logs that the installer generated:

If it matters, I previously had manjaro installed on the drive I’m trying to setup endeavour on now. With manjaro the boot menu turned on automatically on startup and allowed me to choose a system.
Is it possible to get the same result with endeavour?

Thanks in advance!

Please send output of

Looks like you are doing an MBR/Legacy install on a disk with GUID partition table.

This is called BIOS/GPT :sweat_smile:
Also EndeavourOS is one of the very few distributions which is OOB capable of doing that.

Sorry, I don’t really follow. Could you explain how I can fix it?

I have never tried it myself.

So that would mean that EnOS’ Calamares will create the required Bios boot partition on a GPT disk if you do a MBR/Legacy install?

Probably yes if you boot in Legacy mode and use an empty disk.

If I am reading the output of fdisk -l correctly, your Windows is installed in UEFI mode on a GPT disk.

I would suggest to install EnOS in UEFI mode as well.
That means you need to boot your Live USB in UEFI mode and let the installer automatically create all needed partitions for you “erase and install”.

Go into Bios and disable Legacy/CSM boot mode and then boot up your Live USB.

While doing what @pebcak mentioned, don’t install EnOS bootloader to Windows disk, install it to EnOS disk.

That’s something I need to test on some occasion.

That solved my problem, everything now works as intended. Many thanks!

Glad to hear that!
Enjoy your EnOS and welcome to the community @akip!
