I didn’t want to actually change the BIOS, so I didn’t provide the password. When I pressed Enter to continue, BitLocker prompted me for my password (Label and ID blacked out): BitLocker promptly reported that “the system boot information has changed”: So I booted Windows 7 with the Kon-Boot disk in the CD drive. Even with a full backup, there is a risk that it might corrupt the BIOS or otherwise make the computer unusable. If a thief could simply log on to my BitLocker-protected system, the encryption would be useless.Ĭaveat: I have no idea if Kon-Boot can harm a computer and/or upload data.

I wondered if BitLocker was vulnerable to this kind of program.

Recently though I read about a password “bypass” program called Kon-Boot that dynamically replaces the Windows kernel during bootup and allows logging in with any password. BitLocker encrypts the hard drive so that if my laptop is lost or stolen, it should not be possible to access the data on the drive even if you remove the drive and attach it as a second drive to another system. I’ve been running Windows 7 with BitLocker for a couple months and am quite pleased with it.
