Hi. Debian 9.2.1 MATE. LUKS-encrypted via Debian Installer from 9.2.1 DVD. Current partition scheme: EFI; Windows 10; Debian /boot; LUKS-encrypted Debian /root & /swap; Unallocated; Windows 10 Recovery.
I'd like to have a second, LUKS-encrypted install of Debian on the unallocated partition, so that I'll ultimately be able to choose between booting Windows, Encrypted Debian A and Encrypted Debian B from the default Grub boot menu. If I try to accomplish this with the 9.2.1 install DVD, will Debian Installer be aware of the existence of the pre-existing Debian install when generating/updating Grub? Thanks.
