If there is a vdi attached (this is always detected, probably as FS0:), you might find a new like FS1: First type the 'drive' to boot from, here FS0. To do this you should now see an additional drive (here FS0: - no other drives are attached to my VM). If not you need to provide the boot file manually. You might be lucky and the system is already booting from USB. Now reset the machine (not power off) using the menu or hit Hostkey+ R (ususally Hostkey is RightCTRL). If there is a general issue to mount an USB drive to a VM, see this post VirtualBox Error: USB device is busy with the previous request. However on some systems unfortunately right after start the USB-Stick might not be detected: If the USB-drive is already detected, skip this step (the reset). Now add the wanted USB device to the config to automatically mount it on start I was not able to boot from USB in BIOS mode, so enable the EFI mode! VirtualBox IS able to load from USB! However it is a bit tricky. I managed to boot this way in 2014 :) ( - the source article is from 2009) Now you can attach the vmdk (example: e:\my_redirect_for_usb.vmdk) in Virtualbox like you do with any other hdd image You can write the whole thing in one line, instead - just leave out any ^, then. Replace in \\.\PhysicalDrive with the number of your Physical drive, example: \\.\PhysicalDrive1 if your drive number is 1 (got from diskmgmt.msc above!)Īside: note, that ^ only means "line-continuation" in cmd - i did this only for better readability. Replace to a path of your choosing, for the "redirect" disk file. VBoxManage internalcommands createrawvmdk ^ Open/run diskmgmt.msc and check which disk number did windows choose for your physical pendrive: in windows hostĪttach your physical usb pendrive to your host computer here is the windows way (only, link contains it for linux too). According to harrymc's source: you can not set up to boot from USB in the GUI, however, you can create a special virtual disk that only "redirects" to your physical usb pendrive, and attach that.
