This question already has an answer here:

I press F12 repeatedly to select boot device.

AHCI controller:

  • Hard disk

Other boot devices:

  • floppy
  • CD
  • LAN
  • continue booting

I followed How to boot from a USB drive in VirtualBox? box and the commands of vbox users to add it. but is plop boot manager compulsory?

I have guest-additions and virtualbox-extension pack installed and even my san disk lists in the settings menu -> USB .

Virtualbox does not support booting directly from USB. However, it does support booting directly from .iso files. So there are two options:

1) You can boot from a Plop Boot Manager .iso (or something like it), then use Plop to boot from your USB drive (see How to boot from a USB drive in VirtualBox?); or

2) Boot from a different .iso file within virtualbox. For example, if you're trying to install Ubuntu in Virtualbox with an Ubuntu USB stick, you can skip the usb stick completely. Instead, mount the Ubuntu .iso file as a "virtual DVD drive" to boot from it directly.

  • genius, right, now i will use the iso's. so the terrance advice was for iso not USB. i didnt knew that. thx. – koe May 7 '16 at 19:58
