Am I doing something wrong installing using LUKS in dual boot?
I've got a dual boot system with Win 8 installed, I'm re-installing ubuntu 13.10 along side to enable full disk encryption, following this guide almost to the letter: How can I install Ubuntu encrypted with LUKS with dual-boot? The only difference is that I don't create a new boot partition (there is already an EFI boot partition), and I use two partitions for home and / (probably pointless as they're both in the same LUKS container)
Creating the LUKS container and partitions seems to go fine (no errors reported certainly). So I finish the graphical installer, but it fails with: The 'gub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot.
I've tried this twice now, and got the same thing both times.
The machine is a Dell xps 15 (l521x) I'm using an ubuntu 13.10 live dvd. I previously used the same dvd to install next to the same windows install, just without the LUKS stuff, and it worked with no problems.
EFI - fast boot and secure boot are disabled.
I'm also a relative linux newb, and have never dealt with EFI or disk encryption before.
This question has a similar problem, but on 12.04, and without LUKS.
