 How to Install Ubuntu on Your PC – A Step-by-Step Guide for Beginners (2025)

What You’ll Need

A USB flash drive (at least 4GB, 8GB is better)

A computer (of course 😄)

Ubuntu ISO file – https://ubuntu.com/download/desktop

Rufus (for Windows) or Balena Etcher (for any system) – to create a bootable USB

Optional but recommended: Back up your data!

Step 1: Download Ubuntu

Go to https://ubuntu.com/download/desktop

Choose the latest Ubuntu Desktop version (like Ubuntu 22.04 LTS)

Click Download

Step 2: Create a Bootable USB

Download and open Rufus – https://rufus.ie

Plug in your USB stick

In Rufus:

 - Device: Choose your USB

 - Boot selection: Pick the Ubuntu ISO you downloaded

 - Partition scheme: Use GPT (for modern UEFI systems) or MBR (for older BIOS)

Click Start and wait for it to finish

Alternatively, use Balena Etcher if you’re on macOS or Linux.

Step 3: Boot from USB

Restart your computer

As it’s restarting, press the BIOS/boot key (often F2, F12, DEL, or ESC – depends on your PC model)

From the boot menu, select the USB device

You’ll now see Ubuntu loading!

Step 4: Try or Install Ubuntu

You’ll get two options:

 - Try Ubuntu – lets you test it without changing your system

 - Install Ubuntu – starts the full installation process

Click Install Ubuntu when you're ready.

Step 5: Installation Type

Erase disk and install Ubuntu – for a clean install (WARNING: this will delete everything!)

Install alongside Windows – if you want a dual boot setup (you’ll choose between Windows and Ubuntu when starting your PC)

Choose what suits you best.

Step 6: Set Things Up

Choose your language

Connect to Wi-Fi

Pick Normal or Minimal Installation

Select your time zone

Create a username and password

Click Install Now, confirm the changes, and let Ubuntu do its thing.

Step 7: Finish & Reboot

Once installation is complete:

 - Remove your USB when prompted

 - Click Restart

Boom! You now have a fresh Ubuntu system ready to use.

Bonus Tips After Installation

Update your system:

  sudo apt update && sudo apt upgrade -y

Enable firewall:

  sudo ufw enable

Install additional drivers:

  Go to: Settings → Additional Drivers

🔧 How to Disable Driver Signature Enforcement on Windows 11 Pro & Windows 10 (Step-by-Step Guide)

Have you ever tried to install a custom or unsigned driver on your Windows PC, only to get blocked by Windows with a warning about "Driver Signature Enforcement"? Don’t worry—you’re not alone.

Whether you’re trying to flash a phone, install legacy hardware, or run custom tools, this security feature can get in the way. In this post, I’ll walk you through how to disable driver signature enforcement on Windows 11 Pro and Windows 10, step by step.

⚠️ Note: This process is safe, but disabling signature enforcement means Windows will allow installation of drivers that haven’t been signed by Microsoft. Be sure you trust the source.

🪟 What Is Driver Signature Enforcement?

Driver Signature Enforcement is a security feature that ensures only Microsoft-verified drivers can be installed on your system. While it protects you from malware or unstable drivers, it can be a pain when working with custom drivers, especially in the repair and tech field.

---

🧩 Method 1: Temporarily Disable Driver Signature Enforcement

This is the easiest method, and the changes will reset after a reboot. Ideal if you just need to install a driver once.

✅ Steps for Windows 11 & Windows 10:

1. Click on Start Menu, then press and hold Shift, and select Restart.

2. Your PC will boot into a blue Recovery Menu.

3. Choose Troubleshoot.

4. Then click Advanced Options.

5. Select Startup Settings.

6. Click on Restart.

7. Once your PC restarts, you’ll see a list of options.

8. Press the F7 key to disable driver signature enforcement.

💡 Now install your unsigned driver. The enforcement will be back ON after the next reboot.

---

🧩 Method 2: Permanently Disable Driver Signature Enforcement (Advanced)

If you’re a technician or need this disabled permanently, follow this advanced method using Command Prompt.

⚠️ WARNING: Use this only if you're aware of the risks. Keep a system backup.

✅ Steps:

1. Open Command Prompt as Administrator:

   • Search for cmd in the Start Menu.

   • Right-click and select Run as Administrator.

2. Type this command and press Enter:

   csharp
   bcdedit /set nointegritychecks on
   

3. You should see a confirmation message like:

   "The operation completed successfully."

4. Restart your computer.

💡 Done! Your Windows will now allow unsigned drivers to install freely—even after reboot.

🔄 To Re-Enable Signature Enforcement:

If you want to reverse the setting, follow the same steps and run this command:

vbnet
bcdedit /set nointegritychecks off

---

💡 Bonus Tip for Technicians

If you're installing Qualcomm, MTK, or SPD drivers for phone flashing tools, disabling signature enforcement is often necessary. Make sure you always get drivers from trusted sources to avoid corrupting your system.

---

✅ Summary

Method	Type	Resets After Reboot?	Difficulty
Method 1	Temporary	✅ Yes	Easy
Method 2	Permanent	❌ No	Medium

---

🗣️ Final Thoughts

Driver Signature Enforcement is a helpful feature—but sometimes, it just gets in the way, especially for people in tech, phone repair, or custom hardware installation.

With this guide, I hope you now feel confident enough to bypass it when needed—whether you're using Windows 10 or the latest Windows 11 Pro.
