How to boot BCVE encrypted system from the network


BCVE boot with two-factor authentication

In two-factor authentication mode BCVE transfers encryption keys to external location and erases them locally. Thus it needs an external boot loader to boot with encryption keys. BCVE uses Syslinux family of boot loaders for this purpose.

Syslinux family support booting from USB flash, network (PXE), CD/DVD media. BCVE creates universal boot file capable of booting from all the sources above. It also makes ready to use bootable USB flash disks and CD/DVD disk images. Unlike them, the network boot environment for BCVE has to be configured manually.
