<string lang="en" key="CUSTOM_BOOT_LOADER_MESSAGE_HELP">Note: In some situations, you may wish to prevent a person (adversary) that is watching you start the computer from knowing that you use VeraCrypt. The above options allow you to do that by customizing the VeraCrypt boot loader screen. If you enable the first option, no texts will be displayed by the boot loader (not even when you enter the wrong password). The computer will appear to be "frozen" while you can type your password. In addition, a custom message can be displayed to mislead the adversary. For example, fake error messages such as "Missing operating system" (which is normally displayed by the Windows boot loader if it finds no Windows boot partition). It is, however, important to note that if the adversary can analyze the content of the hard drive, he can still find out that it contains the VeraCrypt boot loader.</string>
