Unlike some people I know from forums, I want to share my effort with YOU.
I was trying to edit that background with 16 colours 4 bit palette in Photoshop, but everytime failed.
I tried with Windows "Paint" and I succeed but I needed to make painting (dot by dot) manually and at the end I had working background but visible in ResHack or PE Explorer or other editing tools unlike MS's non-visible with mentioned tools.
Last night I found that using TuneUp Utilities can make the original like MS's background without much effort
In the folowing tutorial, I'll try to explain the step-by-step how to make the bootscreen like you desire.
01. Download and install "TuneUP Utilities 2009"
02. Start the program and select "Customize Windows"
03. From a "TuneUP Styler" menu, select "Change boot screen"
04. You can see now the Windows default boot screen (active) (ntoskrnl.exe). We are ready to make our own background
05. Click on "New Screen" and by clicking "Open image" select your favourite (background) BMP or JPG image
06. At "Customize progress bar" select the position of border (if you don't want to change the position leave it default) and the colour of the moving stripe
07. "Save boot screen" with the name you want
08. Select the boot screen you just made (selected by default) and click install
09. Now open the folder C:\WINDOWS\system32 and search for file named "TUKernel.exe" and copy it to the desktop
10. Return to folder C:\WINDOWS\system32 and search for file named "ntoskrnl.exe" and rename it to something else (Old.exe for example) and cut/paste it to desktop
11. Rename the TUKernel.exe file to ntoskrnl.exe and paste in into C:\WINDOWS\system32 folder
12. Return to TuneUP Utilities, set the Windows default boot screen as active and delete the new maden (by you) boot screen
13. Reboot and delete the "Old.exe" file from desktop after reboot
For those who want to use TuneUP Utilities and don't want to waste their time, consider step 9 to 13 unessential.
For those who want to "practice" go to the step 13
This method is tested on Windows XP Professional SP3 with ntoskrnl.exe 5657 version and will work for desktops and laptops. It will also work with 5512 version unless you update.
P.S.: TuneUP Utilities uses the original ntoskrnl.exe and modify the file with your background image and create it's own file named "TUKernel".
