Troubleshooting Persistent Boot Loop and Inaccessible Boot Device on Acer Nitro 5

Are you experiencing a frustrating boot loop on your Acer Nitro 5 and unsure of the underlying cause? Recent user experiences highlight common issues such as error messages like “INACCESSIBLE_BOOT_DEVICE (0x7B)” and previous blue screens, which can be daunting to diagnose and resolve.

Understanding the Problem

Initially, the user reported spontaneous system crashes accompanied by the “IRQL_NOT_LESS_OR_EQUAL” error, a Blue Screen of Death (BSOD) indicating potential memory (RAM) issues. As the troubleshooting progressed, the problem intensified, culminating in a persistent boot loop with the error “INACCESSIBLE_BOOT_DEVICE (0x7B).” This error suggests that Windows is unable to access the system partition during startup, often linked to driver problems, corrupted system files, or hardware failure.

Potential Causes

1. Faulty RAM Modules: Given the initial suspicion of RAM issues, faulty memory could have triggered the initial crashes. However, ongoing problems might imply other underlying factors.

2. Corrupted System Files or Drivers: System corruption or incompatible/stale drivers can prevent Windows from booting properly, especially after crashes.

3. Storage Device Issues: A failing or disconnected SSD/HDD can cause boot device errors like 0x7B.

4. Hardware Failures: Other hardware components, such as the motherboard or cables, might also contribute, especially if the device is difficult to access or service.

Recommended Troubleshooting Steps

1. Access BIOS Settings: Since the user can enter BIOS, this is a good starting point to verify hardware detection—check if the storage device appears correctly.

2. Attempt Safe Mode: Though initially inaccessible, try booting into Safe Mode with Advanced Startup options. This can often be achieved through repeatedly pressing F8 or by interrupting the normal boot process three times to trigger automatic recovery.

3. Run Startup Repair: Using a Windows recovery drive or installation media, boot into recovery mode and select “Startup Repair.” This tool can fix common issues preventing Windows from booting.

4. Check Hardware Connections: If comfortable, consider inspecting your laptop’s internals. Given the user’s hesitance to disassemble, it’s advisable to follow manufacturer guides or seek professional assistance for hardware inspection or RAM replacement.

5. Test RAM Modules: If you are experienced and confident, testing RAM modules individually with dedicated
