Question
Help with batch file to run after WinPe boot up, assign usb thumb driver letter to specific letter?
Long story short, I would like to boot winpe and have it always assign the usb thumb drive to be drive letter T:\. We are using WinPe booting off of usb thumb drives as part of our imaging process. Originally I setup the imaging scripts to be drive letter E:\ on all the thumb drives, now with tablets, I had to go back in and set those to be drive letter D:\ (since they do not have cd rom drives). If the pc's have hidden restore partitions winpe assigns the usb thumb drive to letter F: or G:. Thus we have to manually go into Diskpart, select volume, assign letter=E, etc..
I am working on some batch files to do a
diskpart, list volume, pipe that into text file or another command to (this is where I am stuck) then select the removable volume and eventually assign letter=T.

In WinPe, it did not like the Findstr, changed, set TargetLabel=Removable, and added, echo %USBVol%
echo %OldLetter%
echo %USBLabel%
then it worked like a charm each time, maybe a timing issue.
Final script
@echo off
setlocal
set TargetLabel=Removable
set TargetLetter=T
echo list volume > %Temp%\DiskPart1.txt
echo exit >> %Temp%\DiskPart1.txt
for /f "tokens=2-4" %%a in ('diskpart.exe /S %Temp%\DiskPart1.txt ^| find /I "%TargetLabel%"') do (
set USBVol=%%a
set OldLetter=%%b
set USBLabel=%%c
)
echo Drive with label "%USBLabel%" is "Volume %USBVol%" and currently assigned drive %OldLetter%:
echo %USBVol%
echo %OldLetter%
echo %USBLabel%
echo select volume %USBVol% > %Temp%\DiskPart2.txt
echo assign letter=%TargetLetter% >> %Temp%\DiskPart2.txt
echo exit >> %Temp%\DiskPart2.txt
diskpart.exe /S %Temp%\DiskPart2.txt
echo Drive letter of "%TargetLabel%" should now be %TargetLetter%:
pause
Saved it as setusb2t.cmd
Next test will be to add it to the winpe image and have it launch automatically with startnet.cmd.
Thank you for all your help!!!

You can get the letter of the drive that the batch script is running on with the variable %~d0. See here for more information.
You could then use this to generate a diskpart script or a subst command. For instance, the command below temporarily maps the T: drive to the script's drive.
