This article will guide you on how to Reinstall Windows on an AMD StoreMi enable CyberPowerPC computer with AMD StoreMi enabled on the primary hard disk drive.
Cleaning Disks Previously Used as a StoreMI during Windows Setup
When do I need to use this procedure?
The following steps are only necessary if re‐using StoreMI disks from a previous installation in a new installation and you are experiencing difficulties getting Windows to recognize the disks or trouble with getting the StoreMI software to correctly recognize the disks during a transform.
Why should I use this procedure?
AMD places data on the raw drives when creating a StoreMI. If you end up reusing these disks in a new bootable StoreMI installation, then it will be necessary to use the Windows built-in program diskpart to completely clean the disks BEFORE reinstalling Windows and re‐using the drives.
For EFI setups, during Windows setup, using the Delete option presented in the Windows installer disk selection is not sufficient as it only cleans part of the disk drive and the AMD metadata is still left on the drive which can cause issues with the install of a new Windows or StoreMI installation.
For EFI, the previously used disks will be labeled "EnTier_ESP" in the Windows disk select window. In the above example, Drive 0 is one of the drives in question for example. Identify any others by scrolling down the list.
If you used your drives as data only StoreMIs, we will need to identify them using diskpart as they will not be visible in the Windows disk selection menu.
How to clean the disks
- Power on your computer with your bootable Windows Install Media connected. If you have not yet created a bootable Windows Installer Media, please follow the Microsoft guide on how to Create Windows 10 installation media
- Follow the setup prompts until you get to the section titled Where do you want to install Windows?
- From the disk selection menu, press Shift and F10 keys at the same time to open a command line prompt.
- In the Command Prompt window, type diskpart.
- You should now be in the DISKPART app, type list disk.
For our example, we have three disks. Disk 0 and 2 were previously used as StoreMIs. Drive 1 is an extra boot master drive we are also going to clean while in diskpart.
- Identify the Disks previously used as a StoreMI. Use the size of the disk if necessary, and take special care NOT to accidentally select the Windows setup USB disk (for our example, Disk 3 above) or any other drives you may have left attached. It is highly recommended if you see multiple drives and you cannot clearly identify which were the StoreMI raw disks, shut down your machine and disconnect any data drives or drives you do not want to touch, then reboot to try again.
- To clean (i.e. delete all data and metadata off) the disk you have previously identified as StoreMI drives you will need to type select disk # (where # is the digit of the disk we want to clean so for example for Disk 0 we would type select disk 0) then press the return key.
- You should now see a message "Disk # is now the selected disk."
- type clean and press the return key. Once it is complete there will be no notification, it will just return to the prompt.
- If for the example above we needed to clean disk 0 and 2 we would repeat step 7 with disk 2 instead.
- Once you've completed the cleaning of the appropriate drives, type exit to leave the diskpart app.
- Close the command prompt window and return to the Windows setup disk select menu.
- Refresh the disk select window to show the clean drives.
- Any legacy BIOS mode or data StoreMIs should now correctly appear as empty drives and all StoreMI metadata will be safely removed.
- Proceed to install Windows on the drive of choice.
