9 Fixes: PC Won't Boot After Enabling Secure Boot

Here, we listed the 9 solutions that can resolve PC won't boot after enabling Secure Boot. Continue reading to learn the details.

1. Method 1: Disconnect External Drives
2. Method 2: Remove CMOS Battery
3. Method 3: Convert MBR Disk to GPT
4. Method 4. Update BIOS Version
5. Method 5. Update SSD Driver
6. Method 6. Repair with Third-party Software
7. Method 7. Boot from Bootx64.efi or Bootia32.efi Manually
8. Method 8. Check for Windows Updates
9. Method 9: Perform Clean Install

Method 1: Disconnect External Drives

While additional storage or backups are convenient, external drives can sometimes pose an issue during the boot process. When connected, these drives might inadvertently interfere with the system's startup sequence, causing the Windows PC to falter after enabling Secure Boot.

To troubleshoot this issue, disconnect all external drives from your PC. This will eliminate the potential interference and allow the system to boot without external requirements.

Try it and see if this straightforward action resolves your boot problem. Often, a quick disconnect can be the key to getting your Windows PC back on track. Proceed to the next section once you've given this a shot.

Method 2: Remove CMOS Battery

Now, let's explore another avenue to tackle the Windows PC boot hiccup after enabling Secure Boot. Sometimes, the motherboard's CMOS battery can cause issues by misjudging the state of Secure Boot, leading to startup troubles.

To proceed, locate the CMOS battery on your motherboard. It's typically a coin-cell battery. Before you begin, ensure your PC is powered off and unplugged. Gently remove the CMOS battery, wait a minute or two, and reinsert it. This brief removal allows the motherboard to reset its settings. Power on your PC and observe if the boot issue persists.

This technique can help ensure a smooth boot process and offers a non-intrusive means of addressing possible misconfigurations. Don't worry if the issue continues; we'll look at other solutions in the parts that follow.

Method 3: Convert MBR Disk to GPT

The partition style of your disk plays a pivotal role in how your system boots. MBR (Master Boot Record) is associated with Legacy BIOS, while GPT (GUID Partition Table) is linked to UEFI, the modern firmware interface. Secure Boot often requires a UEFI environment, and compatibility issues may arise if your disk uses the older MBR style.

This technique can help ensure a smooth boot process and offers a non-intrusive means of addressing possible misconfiguration. Start by examining the partition style of your disk. This could be the source of the issue if it's MBR and you've enabled Secure Boot. Booting from an MBR device can be made easier and more compatible by switching to a GPT.

If you don't want to reinstall the Windows system after converting MBR to GPT, you'll need a reliable partition management tool. Qiling Disk Master Professional is an easy-to-use tool that makes the converting procedure simpler. You can save time and effort by switching to this software instead of reinstalling Windows.

So, if you are experiencing complexity with boot, it's time to consider a BIOS update.

Step 1. In the search box, search for and open "System Information." Then, you can see the BIOS version of your PC. You can also access the information during the initial boot process or within the BIOS/UEFI settings.

Step 2. Head to the official website of your PC's manufacturer. Look for the support or downloads section.

Step 3. Find the right BIOS update for your respective PC model and download it.

Step 4. Ensure a stable power source for your PC.

Step 5. Run the utility for BIOS updates and follow the on-screen instructions.

Step 6. Restart your PC. Once the update is complete, recheck the BIOS version to confirm the successful update.

Remember, updating the BIOS requires careful attention and adherence to manufacturer guidelines.

Method 5. Update SSD Driver

In the intricacy of Windows PC's functionality, even the seemingly small players, like your SSD (Solid State Drive) driver, can play a crucial role. If your PC has boot issues post-Secure Boot activation, an outdated SSD driver might be the problem. An outdated SSD driver can lead to compatibility issues, especially when Secure Boot is in play.

To ensure a smooth and secure boot, it is crucial for the SSD driver to stay updated.

Step 1. In the search box, search for and open "Device Manager." Then, locate Disk drivers and identify the model of your SSD. You can also find it by checking your PC's specifications.

Step 2. Find and download the latest SSD driver compatible with your model from the official website of your SSD manufacturer.

Step 3. Before proceeding, back up any crucial data on your SSD.

Step 4. Run the downloaded driver file and follow the on-screen instructions to install the new driver. This might involve extracting files or going through a setup wizard.

Step 5. Restart your PC once the installation is complete.

Updating your SSD driver is a proactive step that addresses the immediate boot issue and contributes to your system's overall health and performance.

Method 6. Repair with Third-party Software

Method 7. Boot from Bootx64.efi or Bootia32.efi Manually

EFI files, denoted by their .efi extension, are pivotal to the UEFI boot process. These files contain executable code necessary for booting the operating system. When dealing with Secure Boot-related boot issues, manually selecting the appropriate EFI file can pose potential hiccups in the automatic boot process.

Step 1. Access your PC's UEFI or BIOS settings by hitting the BIOS hotkeys while booting up. (F1, F2, F10, F12, Del, or Esc.)

Step 2. Navigate to the boot options section of the UEFI/BIOS settings. To boot, manually pick an EFI file. You may find them here:

• \EFI\boot\bootx64.efi
• \EFI\boot\bootia32.efi

Step 3. Select either bootx64.efi or bootia32.efi, depending on your system. Usually, the EFI sector of your system has these files.

Step 4. Save your changes and exit the UEFI/BIOS settings after selecting the proper EFI file. Your system should attempt to boot using the manually chosen EFI file.

By manually invoking the bootx64.efi or bootia32.efi files, you're taking control of the boot process and sidestepping potential Secure Boot-related obstacles.
