Installation Guide
Step 1: Prepare the USB Installer
To make this as painless as possible, we created a bootable Linux Mint USB image with everything you need pre-installed.
- Download our custom Linux Mint image (4GB torrent file)
- Download balenaEtcher - compatible with Windows, macOS, and Linux
- Start balenaEtcher and click Flash from file
- Select the Linux Mint image you downloaded
- Insert USB drive and click Select target
- Double-check you selected the USB drive, not your main hard drive!
- Click Flash and wait for completion
💾 USB Requirements: Any USB drive 4GB or larger will work. USB 3.0 recommended for faster installation.
Step 2: Boot Your Old PC from USB
Configure your PC to boot from the USB installer:
- Power off the PC and insert the USB drive
- Power on and immediately press ESC, F12, or DEL to enter BIOS
- Navigate to Security tab
- Set Secure Boot to Disabled
- Go to Boot tab
- Set Boot Option #1 to your USB drive
- Save changes and exit
🔧 BIOS Access Keys: Common keys are ESC, DEL, F2, F10, or F12. Check your PC's manual if unsure.
Step 3: Boot into Linux Mint
Your PC should now boot from USB. When you see the boot menu, press ENTER key four times to proceed to Linux Mint Desktop.
Step 4: Install PrivateRouter OpenWRT to Hard Drive
Now we'll install OpenWRT to your PC's hard drive:
- On the Linux Mint desktop, double-click balenaEtcher
- Drag the OpenWRT image file into balenaEtcher window
- Click Select target
- Click "Show hidden" to see system drives
- Select your system drive (usually /dev/sda)
- Click Flash to begin installation
- Confirm by clicking Yes, I'm sure
⚠️ Data Loss Warning: This will erase ALL data on the selected drive. Make sure you've backed up anything important!
Step 5: Create Docker Partition
After installing OpenWRT, we need to create a partition for Docker containers:
- Close balenaEtcher after completion
- Double-click GParted icon on desktop
- Select your system drive (/dev/sda) from dropdown
- Right-click the unallocated space
- Click New
- Keep ext4 format and click Add
- Click the checkmark to apply changes
- Shutdown PC and remove USB drive
Step 6: First Boot Configuration
🌐 Internet Required: Connect an Ethernet cable with internet access before first boot. OpenWRT will download drivers and updates.
Boot into PrivateRouter OpenWRT:
- Connect Ethernet cable with internet access
- Power on the PC
- Wait 5 minutes for automatic updates
- Reboot when updates complete
- Connect another PC via Ethernet
- Access http://192.168.70.1 in browser
- Click Login (no password required initially)
📡 Network Adapters: If your PC has only one Ethernet port, use a USB Ethernet adapter. The UGREEN USB 3.0 adapter has built-in driver support.
Step 7: Configure Docker Storage
Mount the Docker partition we created earlier:
- Click System tab
- Select Mount Points
- Click GENERATE CONFIG
- Click MOUNT ATTACHED DEVICES
- Find /dev/sda3 and click EDIT
- Check Enabled
- Enter mount point: /opt/docker2
- Click Save
Configure Docker to use the new partition:
- Click Docker tab
- Select Configuration
- Set Docker Root Dir: /opt/docker2/
- Click Save & Apply
- Reboot to complete setup
