This problem sounds familiar, I have had these kinds of problems many times and almost always with
computers with UEFI. I suspect that the computer tries to find an UEFI partition in your SD card & USB stick,
but since there is not such partition, it won't boot from it.
The distro (when installed to an SD or USB card / stick ) has a "legacy" boot partition. Not UEFI and not GPT.
It has the good old Master boot record scheme (MBR), so I think you should go back to your BIOS settings
and set everything that has something to do with booting to: as legacy as possible.
Disable UEFI booting if it is possible. Check the boot order and set the stick to be the first boot device. And if
possible, the ONLY boot device. Also see if your BIOS USB settings have been set to legacy mode, if there is such
possibility in that BIOS.
Also some BIOSes need to have the first partition in the installation stick to be set bootable/active. Please check
that too. You should be able to set that partition active using either Windows or Linux. In Windows check the stick's
properties and mark it active if it is not. In Linux, use fdisk tool.
I hope this helps. Please tell if it doesn't
