I set my USB to be viewed as a raw disk using:

VirtualBox raw disk emulation (The most recommended method from what I can tell). The Win 7 AIO installer I plan to use is one of these. If all my Windows installers on this USB were in ISO that would be no problem, but two of them required dumping the ISO contents onto the USB root since they didn't support emulation. It was made with RMPrepUSB and it works perfectly from a normal BIOS boot in physical machines. I think the issue might be in the way this thumb drive was prepped. I'm attempting to use USB to install Windows 7 onto a VM.

Despite my best efforts all the workarounds I've found online have failed in some fashion or another. Step 13: Once logged into the guest OS (AKA the virtual machine), open the File Explorer.To start off, I know that VirtualBox doesn't have built in USB boot support, but there are a number of workarounds. Step 12: After selecting the USB drive from the USB list, click “OK” Step 11: Select the USB drive (in this example, a “ JetFlash Mass Storage Device (1100)” is used) Step 10: Click the button located to the right (hovering the mouse over the button will show new USB filter values that are configured with the values of the (chosen) USB device that is connected to the host computer) Step 8: Right-click the desired virtual machine and select “Settings” Step 7: Open the virtual machine list and click the Start Button ( or do as follows: Right click the virtual machine > “Start”> “Normal Start” ) Step 6: A confirmation window will pop-up reading: “ The extension pack Oracle VM VirtualBox Extension Pack was installed successfully ”. Step 5: To confirm the Extension Package installation, click “Yes” ( individuals must use accounts with Administrative permission ) Step 4: After thoroughly reading and understanding VirtualBox’s license agreement, click “I Agree” to continue Step 3: Locate and install the installation file Carefully read the download description, and only download the Extension Pack from trusted sources.Įxtension Packs support includes: 2.0 and 3.0 USB devices, NVMe, Disk Encryption, VirtualBox RDP, as well as Intel Card PXE Boots This is because Extension Packs enhance VirtualBox functionality, and contain software that could pose a risk to a computer that isn’t compatible. Please note: Extension Pack and Oracle VM VirtualBox versions MUST be compatible with each other. Step 2: Download the 10 MB VirtualBox 6.1.4 Extension Pack (named: “Oracle_VM_VirtualBox_Extension_Pack-6.1.4”) Step 1: Open an internet browser (any browser is fine), and visit the official VirtualBox website
