I have followed Debian's instructions ( https://wiki.debian.org/DebianInstall#Creating_a_Bootable_Debian_USB_Flashdrive) for creating a bootable USB stick but it fails to boot on my UEFI laptop. In contrast, I am able to create the same for Knoppix 9.1 following their instructions. So not sure why the debian one doesn't work.
The debian instructions basically say to do a normal cp of the hybrid iso unto the raw USB device as follows (assume USB stick is on /dev/sdf): cp debian11_hybrid.iso /dev/sdf However, although the USB stick ends up with the 2 corresponding partitions, and I can mount/see the content of those, my laptop refuses to recognize the USB stick during boot and so it won't boot off it. I have tried the Debian 10 and Debian 11 hybrid images on 2 different USB sticks and I get the same result. According to [this](https://wiki.debian.org/UEFI#UEFI_support_in_live_images) page the debian live images should boot on UEFI-based systems when USB sticks are prepared as described above... I have inspected the boot options of the laptop in is setup screen, with the USB stick plugged-in, but the USB stick is not listed as a possible target. BTW, in that laptop setup screen I see a note that says that Legacy Boot mode is not supported on the laptop.
