I am trying to follow a new procedure, for me at least, but not succeeding,
and I want to run it by the group for ideas. I have a USB hard disk in an
enclosure, which I can connect to a PC and boot into using the BIOS boot
options when the machine is booted. It is a Linux OS. It runs quite well and
completely independently from the OS on the hard disk inside the PC. I would
also like to be able to boot from this same device using a VM in VBox. Since
there is no option to set up to boot from a USB in the GUI, so far as I am
aware, I looked online for some alternatives using VBox, and I found these
fairly easy instructions:
http://www.pendrivelinux.com/boot-a-usb-flash-drive-in-virtualbox/. Although
that procedure pertains to a flash drive, the principle seems to me to be
just the same; so I thought to apply it to my case.
In the instruction there is an illustration with an image, step #7, but its
image is not exactly like what I see when I start to create a hard disk for
the VM. It may be an older version on which the illustration is based.
Nevertheless, I was able to get around this step by using two steps. First I
created a VM without any disk whatsoever. Secondly, after I created it, I
went into the settings dialogue for the Storage devices and used the
existing Sata Controller to add a disk at that point. I browsed out to the
file that had been created in the online instruction during step #5, and I
chose it. However, I got an error message which I can show here:
Failed to open the hard disk %USERPROFILE%\.VirtualBox\usb.vmdk.
Permission problem accessing the file for the medium
'%USERPROFILE\.VirtualBox\usb.vmdk' (VERR_ACCESS_DENIED).
Result Code: VBOX_E_FILE_ERROR (0x80BB0004)
Component: Medium
Interface: IMedium {29989373-b111-4654-8493-2e1176cba890}
Callee: IVirtualBox {3b2f08eb-b810-4715-bee0-bb06b9880ad2}
Callee RC: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)
I would like some ideas about how to deal with it if anyone has any ideas
what it means. I have no clue at this point. If this method is not going to
work, I will have to try another approach.
