One post tagged with "Dual Boot"

A few months ago, I finally took the time to set up dual boot on my laptop. I would love to try Ubuntu as my daily driver again, while keeping the Windows OS just in case. I treated this as a learning opportunity and configured dual boot with secure boot still enabled and have full disk encryption configured for both operating systems.

I wrote this blog because I could not find a single guide explains all steps for secure boot and full disk encryption sequentially, and these steps interleave each other. So, I made some notes before the installation to ensure I am doing the right thing at the right time. For example, I won't accidentally skip a step about configuring secure boot when I am focused on following another guide about full disk encryption. This guide is a cleaned up version of the notes that I compiled for my dual boot set up.

I organized the whole flow into 6 general steps:

1. Preparing in Windows: set boot mode, partition disk, etc.
2. Configure BIOS: boot mode and other BIOS settings
3. Configure Ubuntu Partition: boot and data partition
4. Install Ubuntu: configure dual boot and mounting volumes correctly
5. Set up crypttab for full disk encryption
6. Reboot and fix some other issues
