Local Build · Step 1

This guide assumes a clean machine and uses Ubuntu 24.04 as the reference system.

Download Ubuntu 24.04 from the official website:

https://ubuntu.com/download/desktop

For users in mainland China, use the Tsinghua University mirror:

https://mirrors.tuna.tsinghua.edu.cn/ubuntu-releases/noble/ubuntu-24.04.3-desktop-amd64.iso

Campus mirror hub: https://mirrors.cernet.edu.cn/

Write the ISO to a USB drive using one of the following tools:

• Rufus: https://rufus.ie/
• Ventoy: https://www.ventoy.net/
• Etchdroid (use your Android phone as a USB drive, for extreme cases): https://etchdroid.app/

1. Reboot into BIOS and select the USB drive as the boot device
2. In the Ubuntu LiveISO GRUB menu, press Enter to enter Live mode
3. Choose Erase disk and install Ubuntu (automatic partitioning), then wait about 20 minutes and reboot

Dual-boot users: Manual partitioning is required. Use a tool like DiskGenius to carve out at least 300 GB for Linux. During installation, create an EFI partition of ≥ 512 MB and assign the rest to /. Use a swap file rather than a dedicated swap partition.
