Larkbox x N100 often boot straight on bios page

Sometimes after many attempts (power off, then unplug power, wait some time, plug it and power on), the BIOS is able to detect the SSD and to start Win 11.
I saw in the user manual to wait at least 10s but preferably 60s … which is a long time and is painful, additionally I am not sure it offers a best chance to start.
It is on a fresh install and update of Win11 (Mini PC received yesterday) SN SLarBXGZ1H240504888

Any idea how to solve this issue?

As i said :
Reinstall the system download everything from here

. I dont know why customers always reinstall a WIndows that is not ours when a new compuiter is just bought. Our computers are customized so they will have issues on other Windows.

If still has same issue, send it back for a replace

I never wrote it is not your windows, it is yours, I just mean we all have to finish the install, choose a PC name, a user name etc. and update Windows, this is part of a fresh install. So I understand it is more an HW issue, than a Windows issue, isn’t it?
