I've an SSD Drive in an external enclosure. It's my old drive. I've a new VivoBook 15 F512DA and when I sent into BIOS I didn't see where I could boot off the USB. So what must I do to book off my SSD drive vs the HDD of the VivoBook?

Thanks

external enclosure contains SSD is right with USB 3.0 or 2.0 ?

Is windows 10 is installed on SSD with EFI Partition too ?

do go to bios, disable secure boot, enable CSM mode save and exit ..

now will you able to see external usb drive..

record a video through smartphone and upload video here.

just now I tested on vivobook 15 X542UQ , I have 250GB M.2 SSD inside M.2 USB 3.0 enclosure , that SSD contains windows 10 with EFI Partition .

so I inserted external usb enclosure in laptop, I went boot menu, windows bootable partition usb is shown, I clicked on that, windows is booted successfully.
