I don't understand what you want to get now.

The partition marked with "*" will be the selected one.

You want all internal partitions, don't you?

What is the output of the:
 

FOR /L %%A IN (1,1,9) DO (
FOR /F "delims=*" %%B IN ('
^(
ECHO SEL DISK 0^&ECHO SEL PAR %%A^&ECHO DET PAR
^)^|DISKPART^|FIND "*" 
') DO CALL :parse_volumes %%B
)
SET Internal
GOTO :EOF
:parse_volumes
SET Line=%*
IF NOT "%Line:~13,1%"==" " SET INTERNAL=!INTERNAL! %Line:~13,1%
GOTO :EOF

On your test machine?

The "Find "*" pipe should limit it to the single partition that is selected :unsure:

 

And what would be the point of removing the subroutine? :dubbio:

 

Anyway:

 

DO SET Line=%%B&&SET INTERNAL=!INTERNAL! !Line:~13,1!

Yes

FOR /F "delims=*" %%B IN ('
^(
ECHO SEL DISK 0^&ECHO SEL PAR %%A^&ECHO DET PAR

)

SET Internal
GOTO :EOF
:parse_volumes
SET Line=%*
IF NOT "%Line:~13,1%"==" " SET INTERNAL=!INTERNAL! %Line:~13,1%
GOTO :EOF
INTERNAL= Z C H F G

The "Find "*" pipe should limit it to the single partition that is selected :unsure:

And what would be the point of removing the subroutine? :dubbio:

I also don't know exactly what I have done. But it gives exactly the same output which I need. It gives me Drive Letters of all partition of Disk 0.

 

Am I using wrong method /approach ? Any better way to get Drive Letter of all partitions of Disk 0 ?

No, that's fine :) , now I see, the loop does run with a selected partition every time, ad thus the "FIND "*" gets just that line, good..

 

The only thing that you can "better" is to avoid the "blind" 1 to 9 loop, it has two kind of issues, it will go on more loops than needed in most cases (when there are less than 9 partitions)  and on not enough in case of more.

Haven't checked, what is the output or list par when there is an Extended partiton (and volumes in it)? :unsure:

 

Removing the external call the drive letter positions is one character off:



@ECHO OFF
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
SET Internal=
FOR /F "tokens=2 delims= " %%A IN ('^( echo SEL DISK 0^&echo LIST PAR^)^|diskpart^|FIND "Parti"^|FIND /V "."') DO (
FOR /F "delims=*" %%B IN ('^( echo SEL DISK 0^&echo SEL PAR %%A^&echo DET PAR^)^|diskpart^|FIND "*"') DO (
SET Line=%%B
IF NOT "!Line:~14,1!"==" " SET INTERNAL=!INTERNAL! !Line:~14,1!
)
)

SET INTERNAL
GOTO :EOF

So there should be no problem if both BIOS and EFI files are within same Boot Partition ?

Yes, there should be no problem if both BIOS and EFI files are within the same Boot Partition.
However there are strange firmware and end users out there. I've the feeling, there are less support request, if you add either or one.

What about a royalty OEM preinstalled Windows?
Do you support this machines?

Example:
There is a NTFS HP_RECOVERY parttion at a UEFI mode HP Z440.
Partition type ebd0a0a2-b9e5-4433-87c0-68b6b72699c7.
There are files \boot\bcd and \efi\microsoft\boot\bcd

And there is a EFI system partition c12a7328-f81f-11d2-ba4b-00a0c93ec93b
There is a file \EFI\Microsoft\Boot\BCD, no \boot\bcd

c12a7328-f81f-11d2-ba4b-00a0c93ec93b is a part of UEFI scepcs. https://en.wikipedia...Partition_Table
Does all manufacturer respect this? Any strange firmwares out there?
What about a missing c12a7328-f81f-11d2-ba4b-00a0c93ec93b partition, but \efi\ at another partition?
As a common configuration, do we use c12a7328-f81f-11d2-ba4b-00a0c93ec93b only?

How does HP recovery works?
Does HP boot \efi\boot\bootx64.efi from the recovery NTFS partition?
Sorry, production machine, no testing.

Partition type ebd0a0a2-b9e5-4433-87c0-68b6b72699c7.
There are files \boot\bcd and \efi\microsoft\boot\bcd

And there is a EFI system partition c12a7328-f81f-11d2-ba4b-00a0c93ec93b
There is a file \EFI\Microsoft\Boot\BCD, no \boot\bcd

Does NTFS HP_RECOVERY partition at UEFI mode HP H440 Partition type ebd0a0a2-b9e5-4433-87c0-68b6b72699c have a Drive Letter assigned in UEFI WinPE ? If it does not have any Drive Letter in UEFI WinPE, then there should be no issue ? But if it already have a Drive Letter assigned then It is really an issue to consider ??

 

Yes, there should be no problem if both BIOS and EFI files are within the same Boot Partition.

If so then how we can accept this exception in your Boot_Found approach ? 

 

What about a missing c12a7328-f81f-11d2-ba4b-00a0c93ec93b partition, but \efi\ at another partition?

I will manually run WinNTSetup to deal with these machines. As a common configuration, I will look for c12a7328-f81f-11d2-ba4b-00a0c93ec93b only.

Or in this case, the thread that never ends. It's hard to believe it's already 6 pages long, especially since the OP titled it "Please help me to go ahead ?". Gee, how descriptive that is, eh? Are you asking a question (the "?" would seem to imply as much)? With a name like that, how are we supposed to know exactly what help is needed with? If OP can't be bothered to write an accurate description of his issue in the title, then I can't be bothered to be of any help (except to post this). And with a name like "devdevadev", you certainly will never be a (software) developer.

Yes, PE assigns a drive letter. In addition, HP is one example, expect other manufacturer with similar recovery files.

I made new assumptions:
-ID c12a7328-f81f-11d2-ba4b-00a0c93ec93b at a GPT disk is the boot partition. \EFI\Microsoft\boot\BCD is not required.
-most likely the \boot\bcd partition is created first. PE assigns a low letter. A recovery partition is created later, PE assigns a higher letter. Assumption: the first \boot\bcd matching is the boot partiton.


The idea is
@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
SET Disk=
SET OSPART=
SET BootPartBIOS=
SET BootPartEFI=
SET CountOSPART=0

REM Detect a GPT disk 0
for /f "skip=9 tokens=2,*" %%a in ('echo list disk ^| diskpart.exe')  do ( 
  set string=%%b
  rem compare last char from string
  if %%a==0 if "!string:~-1!"=="*" (set Disk=GPT& echo Disk !Disk!)
)

REM Search EFI System Partition at a GPT disk 0
if "%Disk%"=="GPT" FOR /L %%a IN (1,1,9) DO (echo sel disk 0
echo sel par %%a
echo det par ) | diskpart.exe | find.exe /I "c12a7328-f81f-11d2-ba4b-00a0c93ec93b" && (
 echo disk 0 partition %%a
 (echo sel disk 0
  echo sel par %%a
  echo remove
  echo assign letter=Z
 ) | diskpart.exe
 set BootPartEFI=Z:& echo BootPartEFI Z:
 if not exist Z:\EFI\Microsoft\boot\BCD echo Warning: File \EFI\Microsoft\boot\BCD missing at EFI System Partition at GPT disk 0
 goto :SearchWindows
)

echo search file \boot\BCD
rem exclude X: and Y: Win10PESE (DVD) drive, 
rem assumption: first hit is the most likely one (default in front of media, PE assigns a low letter) , no validation
FOR %%w IN (C D E F G H I J K L N M O P Q R S T U V W Z) DO (
   if exist %%w:\boot\BCD set BootPartBIOS=%%w:& echo BootPartBIOS %%w &goto :SearchWindows
)

:SearchWindows
echo search file \Windows\system32\config\system
rem assumption: a low letter is the most likely one, validate numbers: multiboot
FOR %%w IN (Z W V U T S R Q P O N M L K J I H G F E D C) DO (
   if exist %%w:\Windows\system32\config\system set OSPART=%%w:& set /a CountOSPART+=1& echo OSPART %%w
)
if %CountOSPART% NEQ 1 (echo Error: %CountOSPART% OS partitions &pause &goto :eOf)


:DoInstall
echo. &echo to do: backup data
echo verify the backup data manually
pause

echo. &echo Apply a install.wim to %OSPART%
if DEFINED BootPartBIOS echo set BIOS or all boot environment to %BootPartBIOS%
if DEFINED BootPartEFI  echo set UEFI or all boot environment to %BootPartEFI%
This is a draft example, expect errors, to be tested and adjusted.

This is the only supported disk configuration for Windows To Go. With this disk configuration, a single Windows To Go drive can be booted on computers with UEFI and legacy BIOS firmware.

 

I know this configuration is for WTG. But Can someone (even myself) not utilize same in Disk 0 to support both UEFI and BIOS ? Will it also work in Disk 0 ?

 

AFAIK, This configuration does not utilizes c12a7328-f81f-11d2-ba4b-00a0c93ec93b GPT Partition but still support UEFI along with BIOS ? May  be your above code already support this configuration too ?

With this disk configuration, a single Windows To Go drive can be booted on computers with UEFI and legacy BIOS firmware.
I know this configuration is for WTG.

Windows To Go is a special case. Some features are limited
https://technet.micr...y/jj592680.aspx

A regular windows expect a GPT disk at UEFI mode.
There are certain limitations at windows setup, sleep mode, windows update, repair install. E.g. Windows 8 setup won't finish at a MBR UEFI disk.
Don't use a internal windows MBR UEFI disk. This is asking for trouble.
No, the script dosn't support this.
Therefore try this at testing hardware manually, no scripting.


 

support at least Dual Booting

That's not a regular setup anymore, this is a exception

Bcdboot.exe adds data to a existing bcd file. Run bcdboot more times.
Call :DoInstall as a subroutine.
 
FOR %%w IN (%INTERNAL%) DO (
   if exist %%w:\Windows\system32\config\system set OSPART=%%w:& call :DoInstall
)
goto :eof


:DoInstall
echo backup and verify data first
echo OSPART %OSPART%
echo BootPartBIOS %BootPartBIOS%
echo BootPartEFI %BootPartEFI%
goto :eof

C:\Users\Kdeva>fsutil volume diskfree C:
Total # of free bytes        : 5348855808
Total # of bytes             : 32767995904
Total # of avail free bytes  : 5348855808

I want to echo Total Capacity and Free Space of C: Drive. Following code works as expected. But what will be the best way to get Exact and Accurate size in GB ?

SET OSCAP=
SET OSFREE=
FOR /f "tokens=1*delims=:" %%i IN ('fsutil volume diskfree C:') DO (
    SET "disktotal=!diskavail!"
    SET "diskavail=%%j"
)
SET OSCAP=%disktotal:~0,-9%
SET OSFREE=%diskavail:~0,-9%

ECHO Total Capacity - %OSCAP% GB
ECHO     Free Space - %OSFREE% GB

Is it the best and simple way to get exact and accurate total size in GB ?

for /F "tokens=2 delims=:" %%a in ('fsutil volume diskfree C: ^| find /i "of bytes"') do set bytes=%%a
set /A OSCAP=%bytes:~0,-3%/1024*1000/1024/1024
echo Total Capacity= %OSCAP% GB

Any better LOGIC to do exactly the same ?

Problem is a GB is 1024 * 1024 * 1024 not 1000000000. Unfortunately cmd.exe set /a only supports 32 bit integers not 64 bit integers. The integers you need to manipulate are much bigger than a 32 bit integer.

 

Look at this link for some ideas:

As it was said before, it doesn't makes much difference to use GiB or GB, and since GiB are much more easy to deal with (if some approximaton is allowed).

 

Should devadevadev choose the unneeded more complex way, he can peruse the batches here:

http://reboot.pro/to...and-hex2deccmd/

to make large multiplications and divisions in batch.

In case script does not found any 'Boot Partition' and/or 'OS Partition' in Disk 0. Then most probably either of the following scenario definitely happen ?

1. There is a 'Boot Partition' along with a formatted  'OS Partition' at the starting of Disk0

2. There is a 'Boot Partition' along with a unallocated space at the starting of Disk0

3. There is a formatted partition at the starting of Disk0

4. There is a unallocated space at the starting of Disk0

 

As a common solution, I will first create a Primary Partition from unallocated space only if maximum allowed Primary partition not already created ? And then set drive letter of newly Created/Totally Empty primary partition to OSPART1. Then I will check if there is a 350 MB or lower primary partition exist ? Is so then set drive letter of newly created 'System Reserved' partition to SYSPART otherwise set SYSPART=%OSPART1%.

Certainly under windows 10 there are some inconsistencies in how it displays volume sizes. According to fsutil my c: size = 209243336704 bytes. By my calculation this is 194.87GB. Disk management shows this as 194.87. Explorer / diskpart rounds down to 194. That would be ok but sometimes explorer does not round down so my external USB drive which has 2 volumes shows these as 48.8 GB and 398 GB where as disk management shows them as 48.83 GB or 48.81 depending on where you look and 398.30 GB ( size as reported by fsutil for first is 52414119936 which I think is 48.81 ).

I wrote a little utility named togb.exe. Its downloadable from here as a winbuilder script:

 

https://paraglidernc...ies/togb.script

 

It will copy the utility to the windows\system32 directory

 

Its called like this:

 

togb 52427719168

 

It will output the value converted to GB or MB depending on parameter value. For the example it will output 48.83 GB to the console.

And in case of need (shameless plug ;)):

http://reboot.pro/to...elease-unwbzip/

 

 

The poor peeps running Windows XP will need to edit (with CFF explorer or similar) the MajorOperatingSystemVersion and MajorSubsystemVerion form 0006 to 0005, after which it works nicely.

Remember to thank the good MS guys for having made the 0006 version "default" in the compiler settings.

 

@Paraglider

With all due respect :), it makes little sense to have the program "automagically" decide the unit of measure, the result will be different (and thus not comparable) when you want to actually compare two very different values, or when one of the two is just below the threshold, I woould have expected something like 1023.999, however:



C:\>togb 1073741823
1023.100 MB

C:\>togb 1073741824
1 GB

It would be better if you made one that always converts to Gb, and one that always converts to Mb (or add a switch to "force" the one or the other".

 

BTW :w00t::



C:\>togb helloparaglider
5771126.24 GB

C:\>togb IamWonkotheSane
2845747.96 GB

togb without arguments just crashes, and togb /? outputs 0 MB

Purpose of togb was to display a disksize in a similar way to explorer / diskmanagement. Yes I could have added some error checking but did not seem to be any point for a small single purpose utility.

I understand, still it makes little sense (to me) to have a tool that decides itself what format to output.

The 1023.100 for 1073741823 remains "queer".
