Create Virtual Machine Disk file ( VMDK) for SD CardĢ-1. Generic- USB3.0 CRW -SD USB Device \\.\PHYSICALDRIVE1 Generic- USB3.0 CRW -SD USB Device 2 31914086400Ģ. In this example, it’s “ \\.\PHYSICALDRIVE1“. You should be able to find an additional line, and that shows DeviceID for the SD card. Insert an SD card to the PC and run the same command. The output should be like this: Caption DeviceID Model Partitions Size List disc drives using wmic command before inserting SD card to PC. “Windows” key + “x” and select “Command prompt (admin)”).ġ-2. Open Command Prompt (or Windows PowerShell) as administrator (e.g. In this post, I use Windows 10 as the host and Ubuntu 18.04 as the guest.ġ-1. Step 1: Right click on the virtual machine that isn’t a bootable state and click on settings.This post shows steps to enable SD card access from Linux VirtualBox guest on Windows host. If you are not sure which of the 2 reasons apply to you, I can show you a solution that covers both, and finally stop receiving the error message. VirtualBox works without any problems when a SATA storage device points to a virtual hard drive, but this is not the case for a bootable iso.
Another issue can be appeared, if you mount accidentally the bootable iso to a SATA storage device controller instead of IDE. The CD/ DVD storage device controller is configured as SATA.If you mount a bootable iso before you start your virtual machine, you will be successful booting up the system. When you create a virtual machine for a first time, you need to mount a bootable iso like Ubuntu. VirtualBox doesn’t point to an operating system, either a mounted iso or a virtual hard disk with a bootable OS.There are two main reasons behind this issue: What causes this “Could not read from the boot medium” error? Note: This problem has to do purely with VirtualBox, and can be experienced on any host operating system be it Windows, Mac OS or Linux. This error is more common when trying to start a new virtual machine, but it is not impossible to happen at an existing virtual machine if the virtual hard drive is missing. Many VirtualBox users have experienced at least once the message ‘FATAL: Could not read from the boot medium! System halted.‘ Sometimes it is also shown ‘ No Bootable Medium Found! System halted‘.
