Ubuntu Setup Guide

This comprehensive guide covers setting up a complete Ubuntu development environment, including package managers, development tools, GPU support, and machine learning frameworks.

0. Pre-installation: Remove Existing Ubuntu (If Needed)​

0.1 Remove Ubuntu from Dual Boot System​

If you need to remove an existing Ubuntu installation from a dual boot system:

Open Diskpart (Windows)​

  1. Press Win + R and type diskpart
  2. Press Enter to open Diskpart with administrator privileges

Commands in Diskpart​

Check available disks:

list disk

Select the disk where Ubuntu is installed:

select disk <disk_number>

Check partitions on the selected disk:

list partition

Select the partition containing Ubuntu system files:

select partition 1

Assign a drive letter for access:

assign letter=P

Delete Ubuntu System Files​

  1. Run Notepad as Administrator
  2. Navigate to P: in File Explorer
  3. Delete the Ubuntu folder in the EFI directory

Remove Assigned Drive Letter​

Return to Diskpart and remove the temporary drive letter:

remove letter=P

Delete Ubuntu Partition Using Disk Management​

  1. Open Disk Management (Win + X → Disk Management)
  2. Locate the partition containing Ubuntu
  3. Right-click and select "Delete Volume"
  4. Optional: Extend another partition into the unallocated space
Important

Always backup important data before modifying disk partitions. Incorrect operations can result in data loss.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add repository
echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
