failed to load external entity "/conf/config.xml"

[laurens]

Hi

I'm using the same hardware since version 8 or something.
I want to upgrade to 12, but I can't boot the LiveUSB. I tried both the MBR and the GPT.

I tried in a USB 2 and a USB 3 port.
XH.. is disabled in the BIOS. There is no BIOS option to disable USB3 support.

Error when booting the installer: failed to load external entity "/conf/config.xml"

please post a link to exact version you are trying to boot.

and pleae confirm what CPU do you use.

is 64bit capable?

do you try rufus?
do you use etcher on mac or windows?

Use the GPT for that motherboard which also supports UEFI BIOS, also try a different image burner such as Win32 Disk Imager , Rawrite32 , physdiskwrite 0.5.3 + PhysGUI if Windows, or if Linux Mint just right click the image and burn to target disk or simply use DD command.

Also use a quality branded USB stick for the installer and target media for best results with Embedded platforms, or a small 2.5" HDD(s)/SSD(s) for RootOnZFS platforms

I tried booting both XigmaNAS-x64-LiveUSB-GPT-12.0.0.4.6625.img.gz as XigmaNAS-x64-LiveUSB-MBR-12.0.0.4.6625.img.gz. Used 2 USB-sticks and a portable SSD disk. I tried UEFI and non-UEFI on both.
I remember that I had the same problem when upgrading from 10 to 11. I forgot how I solved it then, but I think I just placed the disk in another computer to install it.
I used Etcher on macOS and the USB stick boots on my Mac. So it's something related to the SuperMicro board.
The CPU is an 8 core Atom processor C2758.

There are some HP's and select boards very picky on boot indeed, you could try using the LiveGPT-USB and try explicitly booting it on UEFI, alternatively you can install XigmaNAS/GPT on other device then plug the USB stick on target system as you said.
