I am searching for a way to boot from USB.
I have found the possibility via rawdisk and with plobt.
Plobt:
It doesn't find a boot device, although my bootable usb stick is plugged in. (USB 2.0 disabled)
rawdisk gives the following error:
Code: Select all
C:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands createrawvmdk -fi
lename C:\Users\n\Desktop\boot.vmdk -rawdisk \\.\PhysicalDrive1
VBoxManage.exe: error: Cannot open the raw disk '\\.\PhysicalDrive1': VERR_ACCES
S_DENIED
VBoxManage.exe: error: The raw disk vmdk file was not created
#
I have also run as administrator, it haven't helped.
What can I do?

VirtualBox does not support booting from USB.

But some people have already booted from USB.
The instruction is for VirtualBox and seems to be working, but I always get an error creating the rawdisk.

Raw disk access is a dangerous, expert level feature (see the user manual). IMHO, anybody who needs to ask how to use it... should not be using it.

I know, but it is very nerving to restart the computer everytime I want to test my USB boot stick.
Why didn't find the Plobt a boot device, in another thread, some people told, that it worked.

Now it's working with Plobt after restarting the computer.
Because USB 2.0 has to be disabled it is very slow, but for testing enough.

I have the same ploblem:
"VBoxManage.exe: error: Cannot open the raw disk '\\.\PhysicalDrive1': VERR_ACCES
S_DENIED"
but I don't know what do you mean "Now it's working with Plobt after restarting the computer."

I sloved my problem with error message
"VBoxManage.exe: error: Cannot open the raw disk '\\.\physicaldrive1': VERR_FILE_
NOT_FOUND
VBoxManage.exe: error: The raw disk vmdk file was not created"
My solution :
1.my situation: VBox 4.24 + guest os (Win XP SP3);
2.use command "diskmgmt.msc" to check USB drive number, mine is diver1;
3. then rejected the USB disk in the guest OS (Win XP)；
4. Type the command VBoxManage.exe to open the raw disk and create the "usbdisk.vmdk"
The final message is
"D:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands createrawvmdk -fi
lename G:\VBox-XP\usbdisk.vmdk -rawdisk \\.\physicaldrive1
RAW host disk access VMDK file G:\VBox-XP\usbdisk.vmdk created successfully."
Note!. The raw disk cannot be read and create ,if you don't disable or reject it from guest OS.
