Could replicate the issue. When using new [Pi MSD bootmode](https://github.com/raspberrypi/documentation/blob/master/hardware/raspberrypi/bootmodes/README.md#special-bootcodebin-only-boot-mode) it seems the installer gets confused. In my case (PiZero in MSD bootmode, so using a bootcode.bin-only SD; some Pi3...

About previous **Note**, I can confirm if `bootdev` is not set in `cmdline.txt`, although std booting will work (as `datatev` is always set), hitting "Edit menu" will likely not mount...

@chengjianwen After several tests it very much seems the principal issue is that install routine does not set `bootdev=` statement in `cmdline.txt` when operating in MSD mode (i.e. with no...

I'll rephrase: > It expects a Pi 3, an empty USB drive, and that the initial BB files are on the SD card. Can you consider equally supporting other Pi...

What about this: - a PiZero embedded into a case/enclosing device/IOT/etc and SD is not easily accessible (so just have `bootcode.ini `file on it, read only, **never needs updating of...

This usecase is not as specific as it sounds: It applies to **any Pi models** for which one might not want to mess with SD (accessibility may not be sole...

BTW it seems Pi3b+ does support USB-boot off-the-shelf (not need for `program_usb_boot_mode=1`). Therefore current berryboot installer dependency on [`program_usb_boot_mode=1`](https://github.com/maxnet/berryboot/blob/berryboot2015/BerrybootGUI2.0/installer.cpp#L945) to setup USB Boot configuration **also needs to be waived** for...
