Use with caution and **backup everything on another +detached disk** before proceeding. Although it is very unlikely for things to +go wrong when this guide is properly followed, I will not be responsible for any +data loss. + +This guide was first written for Ubuntu 18.04 LTS so some claims may no longer +be true (please let me know if it is false). Doing this guide we'll dual boot +Ubuntu and Windows 10 with setup for encryption of root and home mounts. + +## Questions before we begin + +You need to think about these things before you do anything. I have attached my +personal answers below but it might be different for you. + +- How much space to allocate for Ubuntu? + - ~25 GiB, the recommended minimum is 25 GB and my personal usage has never + exceeded 40GiB for the root drive. + - If you don't have enough space, you may forgo a separate `/home` to gain + flexibility as root space could shrink or grow and it's hard to guess the + sizes upfront. Plus, if your data is on the Windows BitLocker drive, you + could always make a separate drive to keep your data 2 years later when + the next Ubuntu LTS comes out or just restore from backup. Or, you could + make use of LVM... + - After daily driving Ubuntu I switched to separate `/` and `/home` on + top of LVM and keeping at least 5GiB of free space for each LV. When + I need more space, I always live resize by `sudo lvextend -rL +5G + vgroot/lvhome` so I don't have to guess the total size. +- Where should Ubuntu root partition be? + - Right before `/boot` before `D:`. Since moving the starting location of a + BitLocker protected drive needs full data move using an external hard + drive and is lots of hassle, we can consider the beginning of `D:` to be + fixed. putting `/boot` right before `D:` makes its location unlikely to + be affected by moving partitions around so we don't have to deal with any + potential `/boot` hassles which may require reinstallation of GRUB. + - After using it for a while, I've decided to put it at the end of the disk + instead. + - Leaving free space between Ubuntu's root and the Windows drive makes both + OSs easy to resize because it is not hard to change the starting location + of root (GParted can do the job itself) and instead of requiring a full + move in case of expansion of Windows, which is probably more likely, we + require nothing. +- Should you encrypt this partition? + - Yes. There may be sensitive data in `/home/$user/.ssh/`, `/tmp/`, + `/var/log/`, etc. and plus you may want to put the BitLocker key in there + as well for Dislocker and keep them safe in case of losing the laptop. +- Should I encrypt `/boot` or just `/?` + - Just `/`. Encrypting `/boot` provides only somewhat protection against + the kind of Evil Maid where someone changes the kernel and include a + keylogger. This require physical access, and if they have that they can + do more, either: + 1. Install another Ubuntu and connect to the Internet to upload password + 2. Install a hardware key logger + 3. Swap it out for a same-looking machine + - My goal was to only protect against theft and loss, not to protect against + these advanced threats. To do this, you need to either: + - Encrypt `/boot`, which prevents only the swap of a kernel but not any + of the three points above and is hard to implement. + - Password protect BIOS, which makes it very risky when I forget the + BIOS password and protects only against the kernel swap and threat #1. + I consider it not worthy for it adds significant risk only to protect + against the first threat, which is unlikely as I would have to be + specifically targeted by very technical people (they probably could + also disable the password protection or install the keylogger too but + I haven't researched much about this). + - IDK what more could be done. + - Bottom line: never trust the device once it's been tempered with. +- How should I encrypt? LUKS? + - LUKS, I don't want my directory structure to be seen and I want to just + use ext4. +- LVM on LUKS or LUKS on LVM? + - LVM on LUKS, the usual setup with less hassle and I don't need multi-disk + LUKS anyways as this is a single-disk laptop. +- Will dual booting mess up the Windows boot loader? + - Should not, since removing GRUB requires only the removal of its entries + from the EFI partition. +- How to avoid too many password prompts? + - Should have only one prompt at boot when the kernel asks for the password + to decrypt the file systems, and another for normal logins. +- How to dual boot and install with encryption? + - Here is the original guide which I based this one on: [Encrypting disks on + Ubuntu + 19.04](https://medium.com/@chrishantha/encrypting-disks-on-ubuntu-19-04-b50bfc65182a) +- With these questions answered, we can perform the installation. + +## Installation + +- Booting Ubuntu 20.04 LTS live image with `Try Ubuntu` option. +- Verify that we are using UEFI: `$ [ -d /sys/firmware/efi ] && echo UEFI || + echo BIOS` +- Give 1 GiB (or 500 MiB if you are short on space) for `/boot` using GParted and make a partition + for `/` as well, at least around 25 GB. +- `$ sudo cryptsetup luksFormat --type luks2 --key-size 512 --hash sha512 + --use-random /dev/` + - Defaults, spell it out if you want to be extra certain: + `--cipher aes-xts-plain64 --iter-time 2000 --verify-passphrase` +- `$ sudo cryptsetup open /dev/ rootfs` +- No need to overwrite data since it is originally BitLocker encrypted and would + cause loss of performance and lifespan of the SSD. +- `$ sudo pvcreate /dev/mapper/pvroot` +- `$ sudo vgcreate vgroot /dev/mapper/pvroot` +- `$ sudo lvcreate -n lvhome -L 10G vgroot` (`G` refers to GiB according to the + man page) + - Remember to monitor disk usage and when prompted, live extend the LVs! +- `$ sudo lvcreate -n lvroot -L 15G vgroot` +- Start the Ubuntu installation from the shortcut icon on Desktop. +- Choose extra software and set a password. +- Choose `Something else`. +- Format `/dev/` as ext4 and mount to `/boot`. +- Format `/dev/mapper/vgroot-lvroot` as ext4 and mount to `/`. +- Format `/dev/mapper/vgroot-lvhome` as ext4 and mount to `/home`. +- Choose the main disk (`/dev/sd?`) as the `Device for boot loader + installation`. +- Name the parititions if you are feeling fancy. +- Once the installation is complete, click `Continue Testing` to make necessary + changes to load the encrypted partitions at startup. +- Make note of the UUID: `$ sudo blkid /dev/` +- Mount the installed Ubuntu OS on `/mnt` and use `chroot` to change the root + directory to `/mnt`. + ``` + $ sudo mount /dev/mapper/vgroot-lvroot /mnt + $ sudo mount /dev/ /mnt/boot + $ sudo mount --bind /dev /mnt/dev + $ sudo chroot /mnt + # mount -t proc proc /proc + # mount -t sysfs sys /sys + # mount -t devpts devpts /dev/pts + ``` + - In the chroot: `# vi /etc/crypttab` + - Add the following lines to it (replacing `` from the value + obtained from `blkid` command earlier): + ``` + # + pvroot UUID= none luks,discard + ``` + - This guide assumes you have an SSD so we have `discard`. + - Update the Linux kernel to load encrypted partitions at startup: `# + update-initramfs -k all -c` + - Exit the chroot shell. +- Reboot. +- Select Enroll MOK at the blue screen MOK manager.
