debian mini vdi to usb

[netlord]

Hi there

I´ve created an minimalistic UEFI-Bootable debian installation in my virtualbox.
Minimalistic means that there is no gui, only some command line tools i need. The main reason is the UEFI-Boot.

I would like to transfer this image now on an usb stick so I can boot from it.

So i tryed different ways:
1.) like supposed by virtualbox I´ve converted my vdi to an img (VBoxManage.exe" clonehd --format raw debian_mini.vdi debian_usb.img) and wrote this img to an stick -> no boot
2.) I made an dd of /sda to an iso and wrote this to an stick -> no boot
3.) I cloned the image via Clonezilla to an stick -> no boot

The funny think is that my vdi is always booting - OK, it boots into the UEFI shell and I have to add an boot entry every time I´m starting virtualbox, but its booting..
I mentioned that when I´m trying to boot the copy there is no FS0 entry in the UEFI shell.


What I´m doing wrong?
