SCCM USB Stick not booting

If you’re having issues with an SCCM USB stick not booting, that perhaps used to, then it most likely needs some manual input to help it go through.

When you build a USB stick in SCCM, you have the option to Format the USB stick and make it bootable but even after that, it still doesn’t work. Note that the BIOS does recognise it as a bootable media and shows in the bootable devices so that makes you think even more that there’s a different problem.

The solution for the SCCM USB Stick not booting is pretty simple, follow this step and you should be good (these had to be followed already prior SCCM 2012).

  1. Connect the USB stick to a Windows Vista+ device.
  2. Run a command prompt as administrator.
  3. Type DISKPART and press enter.
    1. The command prompt will now take a few instants to go start diskpart
  4. Type LIST DISK and press enter.
    1. This will return the list of disks attached to the machine. Note the Disk Number. In this example we’ll assume the USB disk is DISK 1.
  5. Type SELECT DISK 1 and press enter.
  6. Type CLEAN and press enter.
    1. This command will wipe everything off the USB stick. Make sure you selected the right disk :) .
  7. Type CREATE PARTITION PRIMARY and press enter.
    1. If you receive an error here, then you most likely need to grab a new USB stick.
  8. Type SELECT PARTITION 1 and press enter.
  9. Type FORMAT FS=FAT32 QUICK and press enter.
  10. Type  ACTIVE and press enter.
  11. Type ASSIGN and press enter.
    1. This will assign an available letter to the drive.
  12. Type EXIT and press enter to leave diskpart and repeat this step to exit the command prompt.

Mounting a physical disk or external disk to a VM in Hyper-V

I think that mounting a physical disk or external disk to a VM in Hyper-V is really interesting, especially if you’re looking to attach a USB stick or an external HDD to a virtual machine.
The operation is very simple but I suggest you not to abuse it: mounting a disk through a USB port will result in getting a pretty slow data transfer, but at the same time it’ll result in instant data-portability.

So, in order to do that we just need to mark the disk as inactive. Open a command prompt and type the following.

Now note the disk number you want to attach to the virtual machine, let’s say it’s number 3.
Run this.

You may now exist disk part and go in Hyper-V and attach a new disk to the virtual machine. In the screenshot below I attached it as an iSCSI controller.
