I am attempting to boot a CloudReady image via the SD Card, but even with the "Secure Boot" selected on the bios, I am unable to see it as a boot option.
On my old XPS laptop, if I enable the "Secure Boot" on the SD Card it DOES allow me to see the boot option.
Does anyone else have this issue? I can't even boot a Windows installer from SD.
I don't know as I've never tried.
A USB-based flash-drive would likely be easier.
If it must be something internal/hidden ... an internal drive would be better. You might even get-by with splitting an existing drive into 2 partitions.
Secure-Boot is something completely separate and different from a Secure-Digital Card.
Not sure I was suggesting a dual-boot. Wouldn't you just use F12 to boot that other HDD partition (or drive) when needed ?
Also ... just saw this in the BIOS of a new Intel Tiger-Lake based system ...
There was a BIOS option specifically to allow booting from a SD-Card in the SD-Card slot..
Booting two different OS from a single HD is dual-boot in my mind, sorry for the confusion.
The only way I am able to boot from an SD card on other Dell systems is to enable "Secure Boot from SD". Which once enabled, allows the user to boot an OS thats loaded on the SD card.
Unfortunately I do not believe XPS 13 7390 has this functionality even if the UI exists.
