sounds to me you have nearly done it.

How does the bootmgr.exe.mui get picked over the normal one?

I modified all bootmgr.exe.mui depending upon language en-US, that I got into my ISO folder, but it still not changed text. then after I did peimg /lang=en-us on our mounted image.Is there any way to change resource files (bootmgr.exe.mui) in one shot? thanks for your replies.

[zorphnog]

I don't know. I tried messing around with the mui file as well, but have not been able to get the regular bootmgr to check for it. I think I'm going to try to mess around with the language packs to see how the boot file is incorporated. My fear is that en-US might be the default.

I found some white papers about hacking the bootmgr a while back called VBootKit. It went into detail about the checksum, but I was never able to find where the checksum is stored in the header.

I found a solution for replacing the "Windows is loading files..." text. It involves modifying and adding a bootmgr.exe.mui file. I'm still working out some of the kinks, but I'll post the full instructions soon (probably tomorrow).

Until then, here's a few teaser shots.

Could you please tell me which image you have modified?

Instructions for modifying the "Windows is loading files..." text

Tools needed:

PE CheckSum: Available at The Code Project (sign up required).
A hex editor: I'd suggest HHD's free Hex editor.

Procedures

• Make a directory called en-US in your ISO\boot directory. (en-US is the default. If you use a different locale then you will need to create a folder corresponding to your specific locale. If you are not sure what your locale is for the bootmgr, run this command on your bcd: bcdedit /store %pebuildingdir%\ISO\boot\bcd /enum. Look for the "locale" value located under the {bootmgr} settings.)
  
• Locate the bootmgr.exe.mui file located in your PE image under %imageroot%\Windows\Boot\PCAT\en-US and copy it to your ISO\boot\en-US directory.
  
• Open the ISO\boot\en-US\bootmgr.exe.mui file in your hex editor and go to block 0x0000F050 and edit the "Windows is loading files..." section.
  
   hexedit.jpg (55.81K)
  Number of downloads: 290
  
  IMPORTANT: When editing this section you MUST leave a "dot" between every letter. The "dot" is not a period ".", but rather a 0x00 word. When editing this file, the total size of the file CANNOT differ from the original size of the file. Therfore, replaced text must fit into the original space (cannot exceed 27 characters).
  
   hexedit2.jpg (59.41K)
  Number of downloads: 200
  
  Save and close the bootmgr.exe.mui file.
  
• Open the PE CheckSum tool and browse to your ISO\boot\en-US\bootmgr.exe.mui file. Click the Retrieve button.
  
   checksum.jpg (30.1K)
  Number of downloads: 163
  
  The "Existing" and "Calculated" values should be different. Copy the "Calculated" value to the "New value" text box and click the write button.
  
   checksum2.jpg (30.48K)
  Number of downloads: 127
  
  The "Existing" value should now match the "Calculated" value. Exit the PE CheckSum tool.
  
• Create your iso image as you normally would and your PE image will now load with your custom text.

Glad you cracked it... Well done...

We load PE 2 onto around 300 systems a day here, might put up some interesting statements on the loader.....

[Rakesh Baldha]

Hi Zorphnog,

Great! I am also done. Thanks....

But I did it in another way, your way is also helpful to me.

Steps
1> Make folder ISO\boot\en-US and copy image bootmgr.exe.mui into it from %imageroot%\Windows\Boot\PCAT\en-US.
2> Modified this resource by resource hacker.( freely available on internet ).
3> Done we will get modified text screen.

Thanks really good work you have done for me, thank you very much!

[JuMz]

Sweet! Nice work dude!

[MaciekMR]

Anyone know what happens when I replace bootmgr.exe.mui from ie. PL-pl folder to US-us? This also change "Windows is loading files..." text to ie. PL version?

[zorphnog]

I'm guessing you want to change the bootloader to another language? If that is the case, then placing the pl version of the bootmgr.exe.mui file in the ISO\boot\en-US folder should work.

If that doesn't work, then you will have create a folder for pl, ISO\boot\pl-PL, and place the bootmgr.exe.mui file in there. Then you will have to change the bootmgr language to pl-PL by modifying the BCD (ISO\boot\bcd).

Yep. I just try to change this "Windows is loading..." text without change in any file (copyrights)

I try - I have only pl-pl folder: \boot\pl-pl\bootsect.exe.mui - still english text...

BCDEdit.exe. also works without Vista? AFAIK bcdedit can change boot option off installed OS...

Best regards

en-US is the default language. Its always going to be in English if you don't put bootmgr.exe.mui in a en-US folder or change the bcd. Rename the pl-pl folder to en-US: \boot\en-US\bootmgr.exe.mui

Yes you can use bcdedit.exe. WinPE 2.0 is based off of the Vista kernel/architecture. Thats why it uses BCD and bootmgr to boot from rather than boot.ini and ntldr.

Ok. I've got it to work by replacing the green bars with a picture (no animation).

1. Download and install Vista Boot Logo Generator.
2. Run the generator and add a 800x600 24-bit BMP and 1024x768 24-bit BMP.
3. Save the file as winload.exe.mui.
4. Copy and replace the winload.exe.mui file in the \Windows\System32\Boot\en-US directory of your boot image with the new one.

xcopy /y c:\peimage\winload.exe.mui c:\peimage\mount\Windows\System32\Boot\en-US

5. Capture or unmount your image to ISO\sources\boot.wim
6. Disable the gui option of your bcd entry for WinPE.

bcdedit /store c:\peimage\ISO\boot\bcd /set {default} quietboot yes

Now the green bars will be replaced with your picture!

I must give credit where credit is due, I modified the instructions from this website to work for PE:

http://www.howtogeek.com/howto/windows-vis...-windows-vista/

Kudos, as this works great - my WinPE CD shows my custom boot screen just fine.

The boot.wim that I use on my PXE network doesn't show them, though. I think it's because we aren't changing anything - other than copying the MUI to the mount - before we capture/unmount the WIM.

Any thoughts?

[zorphnog]

You have to edit the BCD for your PXE boot as well. Did you perform step 6 for your PXE BCD? It should be located at <pxeroot>\boot\bcd.

Does anyone have that PEChecksum tool somewhere? I can't get it from the code project (I keep getting an error)

TIA!
