Windows 7: How do I delete it?

I believe it's:

Start> In search box type cmd> Right click on cmd.exe in results and choose Run as administrator> When command prompt opens type

bcdedit /set testsigning off

And press enter. Reboot to see change. A Guy

OK, we can deal with that too

Start> In search box type cmd> Right click on cmd.exe in results and choose Run as administrator> Type in the following

bcdedit /set {current} locale en-US

Press enter

(That would be for english version, if not choose correct locale)

Restart PC to see change

If that doesn't work, use the same method as above and type

bcdboot %WinDir% /l en-US

And restart your system. It should be fine now. A Guy

Sometimes, the beautiful, elegant, high resolution animated and dynamic Windows 7 boot screen UI may be changed to or replaced with Windows Vista boot screen, normally when user adds a Windows 7 entry in boot menu or accidentally when user attempts to repair the startup menu items with Windows Vista DVD, specifically Startup Repair. Windows Vista boot screen is a boring black background with low resolution green running progress bar.

The invalid and wrong boot screen for Windows 7 is due to missing locale entry in boot record, which failed to be set when editing or rebuilding the BCD. When locale is not found, Windows boot loader does not know which boot locale folder to look for the animated bootscreen. Thus, in order to fix the boot screen so that the boot screen can be reverted, restored or reseted back to original animated Windows 7 boot screen, just run one of the following commands in elevated command prompt with administrator rights:

bcdedit /set {current} locale en-US
or
bcdboot %WinDir% /l en-US

Change the en-US to the language version of the installed Windows 7, such as ja-JP, de-DE, es-ES, pt-BR, zh-CN, zh-TW, fr-FR, fi-FI and etc.
Restart the computer after running the command to see the new boot UI (user interface) be used again. To check if the locale setting has been entered properly, just run the bceedit command in command prompt as administrator.

You should then just be able to use the bcdedit -set testsigning off command line (with '-' not '/')
