Using DISKPART & DISM to Clean Install.

Hello @Matthew Wai,

Thanks for testing and reporting the results, it is appreciated.

At least I know that it is NOT me, but rather a PE anomaly. It is strange because it assigns the correct Drive Letter for D:\.

I wonder if it is because the Bootable USB defaults to whatever the PE environment decides that the Drive Letters [ 2 Partitions ] should be.

It is still a quick method as it allocates whatever Drive Letter and the correct Size, it just means that I have to manually change the Drive Letter AFTER the Reboot.

Very strange.

Hello @jimbo45,

Thanks for the alternative method, it is appreciated.

My intention for this Thread was to come up with a quicker, alternative method, rather than physically setting up the Partitions during the setup process, or physically typing in ALL of the Diskpart Commands using Shift + F10.

As @Matthew Wai's results show, it does NOT make a difference if you run the PB_Desktop_Disk_Config.txt directly from Diskpart, or via a Batch Script.

I have already spent a lot of time on this, and for the number of times that I will use it, changing the Drive Letter AFTER the installation is complete is NOT a big problem, especially as it correctly sets everything else up [ Partition, Partition Type, Size ].

I just wanted to close this thread off properly by outlining the methods and processes that I used which worked great!

This is the PB_Desktop_Disk_Config.txt file that I used . . .

Code:

select disk 0
clean
convert gpt
create partition efi size=100
format fs=fat32 quick label="System"
assign letter=S
create partition msr size=16
create partition primary size=30720
format fs=ntfs quick label="W10"
assign letter=W
create partition primary size=51200
format fs=ntfs quick label="Data"
assign letter=D
create partition primary size=20480
format fs=ntfs quick label="Image"
assign letter=I
list volume
exit

This is the PB_Desktop_Disk_Config.bat file that I used . . .

Code:

@echo off
diskpart /s %~d0\PB_Desktop_Disk_Config.txt
set "Index_Number=6"
dism /Apply-Image /ImageFile:%~d0\Sources\install.wim /index:%Index_Number% /ApplyDir:W:\ /Compact /EA
W:\Windows\System32\bcdboot W:\Windows /s S:
echo. & echo ^>Processing Complete. Press ANY key to EXIT . . . & pause >nul

This is the output of the ABOVE Scripts . . .

Although I used I: for the Image Partition, in the output results of the Script above, it showed as E: AFTER a Restart. I therefore changed it using diskpart afterwards . . .

Code:

diskpart
list volume
select volume 3
assign letter=I
list volume
exit
exit

This works great on my newer Desktop. I have an older Laptop that I want to Clean Install using MBR [ as it does NOT support UEFI ]. I want the setup EXACTLY as above, but obviously using MBR - Legacy.

---

I have produced the following to replicate EXACTLY the same as above, but for MBR - Legacy.

This is the PB_Laptop_Disk_Config.txt file that I am going to use . . .

Code:

select disk 0
clean
convert mbr
create partition primary size=100
format fs=ntfs quick label="System"
assign letter=S
active
create partition primary size=30720
format fs=ntfs quick label="Win10" 
assign letter=W
create partition primary size=51200 
format fs=ntfs quick Label="Data"
assign letter=D
create partition primary size=20480 
format fs=ntfs quick Label="Image"
assign letter=I
list volume
exit

This is the PB_Laptop_Disk_Config.bat file that I am going to use . . .

Code:

@echo off
diskpart /s %~d0\PB_Laptop_Disk_Config.txt
set "Index_Number=6"
dism /Apply-Image /ImageFile:%~d0\Sources\install.wim /index:%Index_Number% /ApplyDir:W:\ /Compact /EA
W:\Windows\System32\bcdboot W:\Windows /s S:
echo. & echo ^>Processing Complete. Press ANY key to EXIT . . . & pause >nul

The only thing I am unsure of is should I use shrink instead of directly setting the Partition sizes?

Thanks.
