Removing/changing drive letters

The screenshots in this page have been captured from the Windows To Go system set up in Walkthrough 1, with 64-bit Windows 10 on partition 2 booted/running.

This page covers using the Disk Management Console diskmgmt.msc to remove/change drive letters - restricting access to other operating systems on the Windows To Go drive. This is useful in multi-boot systems to reduce the risk of accidental writes to the offline operating system.

The Windows To Go device has four seperate partitions. Partition 1 contains boot files and is not mounted in the running Windows - this is the default Windows behaviour.

• C:\ (volume label SSD2) - booted operating system on Partition 2.
• D:\ (volume label SSD3) - offline operating system on Partition 3.
• E:\ (volume label SSD4) - Data/shared storage used by the OS on partitions 2 and 3.

Remove drive letter / mount point (diskmgmt.msc)

Using DiskPart to remove/change drive letters

DiskPart can be used as an alternative to the Disk Management Console. As mentioned previouly, the Windows To Go device has four seperate partitions. Partition 1 contains boot files and is not mounted in the running Windows operating system. In this section DiskPart will be used in the Windows To Go Operating System booted from Partition 3 -

• D:\ (volume label SSD2) - offline operating system on Partition 2.
• C:\ (volume label SSD3) - booted operating system on Partition 3.
• E:\ (volume label SSD4) - Data/shared storage used by the OS on partitions 2 and 3.
