Why is my external SSD not recognized?

Okay so. I am running Manjaro on my Lenovo Ideapad 300-15IBR and I bought an external SSD. When I plug it in to the laptop, it works; I can read and write files on it, on USB 3.0 and USB 2.0. Problem is when I try to boot from it. It is not recognized in BIOS nor Boot Menu when I plug it in USB 3.0, but it works in 2.0 BIOS recognize it. Any idea what could be the problem? Thank you **EDIT** Command: cat /proc/cpuinfo | sudo grep "model name" && sudo lshw | sudo grep -A5 "Moth" && sudo lshw | sudo grep product | sudo head -n1 Output": model name : Intel(R) Pentium(R) CPU N3710 @ 1.60GHz model name : Intel(R) Pentium(R) CPU N3710 @ 1.60GHz model name : Intel(R) Pentium(R) CPU N3710 @ 1.60GHz model name : Intel(R) Pentium(R) CPU N3710 @ 1.60GHz description: Motherboard product: Paris G 5A6 vendor: LENOVO physical id: 0 version: NO DPK serial: PF0HH105 product: 80M3 (LENOVO_MT_80M3_BU_idea_FM_Lenovo ideapad 300-15IBR) SSD is Western Digital's My-Passport of 256GB. **UPDATE 2** I made it work. I just used another USB cable for it and it was present in BIOS and Boot Menu. But now I am facing another problem. I have Parrot OS on this external SSD. It boots up. Presents Parrot's loading screen and then I get 3 messages [5.797031] scsi 2:0:0:1: Wrong diagnostic page: asked for 1 got 0 [5.797374] scsi 2:0:0:1: Failed to get diagnostic page 0x1 [5.797424] scsi 2:0:0:1: Failed to bind enclosure -19 After this I get only black screen and nothing else.
