The "EFI Network 0 for IPv4 Boot Failed" error on a Lenovo computer usually means the system is trying to boot from the network (PXE boot) but can't find a bootable device like a hard drive or SSD with an OS installed. This commonly happens when:

• The internal drive isn’t detected or has failed.

• The boot order is wrong.

• The OS is corrupted or missing.

• BIOS/UEFI settings are misconfigured.

🔧 Fixes for "EFI Network 0 for IPv4 Boot Failed" on Lenovo

✅ Step 1: Power Cycle the Laptop

1. Turn off the laptop completely.

2. Disconnect power and battery (if possible).

3. Hold the power button for 10-15 seconds.

4. Reconnect and try again.

✅ Step 2: Check Boot Order in BIOS

1. Turn on your Lenovo and press F1, F2, or Enter (depending on your model) during startup to enter BIOS/UEFI.

2. Navigate to Boot or Startup tab.

3. Ensure your SSD/HDD is listed first, above Network Boot (PXE).

4. Disable Network Boot (PXE Boot) if you’re not using it.

Tip: On many Lenovo machines, press F12 during boot to access the Boot Menu directly.

✅ Step 3: Check if the Drive is Detected

In BIOS:

• Look under Information or Main tab.

• Make sure your internal drive (e.g., SSD or HDD) appears.

• If it's not detected, it may be disconnected or failed.

✅ Step 4: Enable/Disable Secure Boot

• In BIOS, navigate to Security > Secure Boot.

• Try toggling Secure Boot off or on (based on your OS installation type: legacy vs UEFI).

• Also try toggling UEFI/Legacy Boot Mode.

✅ Step 5: Reinstall the Operating System

If the system can detect the drive but doesn't boot:

1. Create a bootable Windows USB using the Microsoft Media Creation Tool.

2. Insert the USB, press F12 at boot, and select the USB.

3. Reinstall Windows.

✅ Step 6: Check Drive Health or Replace It

If the drive doesn’t show up in BIOS:

• It might be dead or disconnected.

• Open the laptop (if you're comfortable) and check drive connections.

• Try replacing the drive and reinstalling Windows.

🛠 If Nothing Works:
