Jumper EZbook 3 Pro v4 can't boot from USB and SSD

[Simon]

Hello,

I have problems with my Jumper EZbook 3 Pro v4.
When I received it, it was perfect! Windows works fine and I could boot from USB.
But I bought a Transcend MTS420 SSD and put it on my laptop.
It has never been recognized by the BIOS. I formatted it on Windows.
I wanted to do an fresh installation from Windows USB but the utility crashed when formatting the SSD.
Since then, I can not boot on a any USB. The screen turns black.
So I cloned the disk (exactly, all partitions) with Easeus To Do Backup on my SSD but it is still not recognized by the BIOS.
When I plug the SSD, the startup is much longer.

Can you help me ? Do you have any idea of the problem?

Many thanks,

Simon

Maybe a BIOS setting?  See the BIOS manual here and the rest of this extensive forum  thread: https://www.linuxquestions.org/questions/linux-laptop-and-netbook-25/jumper-ezbook-3-pro-can’t-boot-from-usb-most-of-common-linux-distros-4175605766/page5.html#post5769515

Thanks for the manual! No, I do not think so. Boot from USB worked before I installed the SSD. I have restored the default settings but it does not change anything 🙁
