Ubuntu - The start of an amazing journey

This guide covers transitioning from Windows to Ubuntu, beginning with setup instructions and progressing through extensive FAQs addressing common challenges.

Initial Setup

Pre-Installation Steps:

• Allocate 200GB+ of disk space via Windows Disk Utility
• Disable Windows fastboot to prevent filesystem conflicts
• Create bootable USB using Etcher and Ubuntu ISO image

Partition Scheme for dual-boot systems:

• Swap: 11 GB (primary)
• Root (/): 75 GB (ext4, logical)
• Boot (/boot): 1 GB (ext4, logical)
• Home (/home): 75 GB (ext4, logical)

Package Management

Essential commands:

sudo apt update
sudo apt upgrade

Understanding sudo privileges before executing commands affecting system directories is crucial.
