“No Bootable Device Found” – What It Means and How to Fix It

Few things are more alarming than turning on your computer and seeing the message: “No Bootable Device Found.”

This error means your system can’t locate an operating system to start from, leaving you stuck at startup. But don’t panic—this is often fixable with a few steps.

What It Is:

Your computer is trying to start up (or “boot”) but can’t find a drive that has a valid operating system (like Windows, Linux, or macOS). As a result, it halts and shows an error on screen.

No boot able device found - how to fix it

Common Causes:

🛠️ Disconnected or Failed Hard Drive: The internal drive may have come loose (especially if the computer was dropped or opened recently), or the drive may have failed entirely.
⚙️ Incorrect BIOS/UEFI Settings: If the boot order is wrong, the system might try to boot from the wrong device—like an empty USB port or network device.
🔄 Corrupted Bootloader or OS Files: Sometimes system files are damaged due to a failed update or improper shutdown, making the drive unreadable during boot.
🔌 Loose or Damaged SATA/Power Cables: Physical connections from the motherboard to the hard drive might be loose or damaged.

How to Fix It:

1. Check the Boot Order in BIOS/UEFI

Restart the computer and enter BIOS/UEFI (usually by pressing F2, F10, DEL, or ESC during startup).
Navigate to the Boot menu.
Ensure your system drive (e.g., SSD or HDD) is listed first in the boot sequence.

2. Reconnect or Reseat Internal Drives

Power off your PC and unplug it.
Open the case (if it’s a desktop) or access the drive bay (for laptops).
Ensure all cables connected to your drive are secure. If it’s a laptop with a removable hard drive, make sure it’s seated properly.

3. Run a Diagnostic Tool

Many PCs offer built-in diagnostics you can access from the BIOS menu.
Run a hard drive test to check for hardware failure.

4. Use a Bootable USB or Recovery Media

If the system files are corrupted, boot from a recovery drive or installation media.
Use the repair options to fix startup issues:
- On Windows: Choose “Startup Repair”.
- On macOS: Boot into Recovery Mode and use Disk Utility.

5. Replace the Drive (If Necessary)

If the drive has failed (you’ll often hear clicking noises or get error codes), it may need replacing.
Restore your OS from a backup or reinstall it using recovery media.

How to Show the Ultimate Performance Plan in Microsoft Windows 10 and Windows 11

by Earendel | Sep 9, 2024 | How To News, News, PC Tips

If you don’t see the Ultimate Performance power plan, you can enable it using Windows Terminal/Command Prompt. Here’s how:

1. Press Windows + X and choose Terminal (Admin). This option may be labeled Windows Terminal (Admin) or Windows PowerShell (Admin) in older versions of Windows.

2. Type in (or paste) the following command and press Enter: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

How to enable the Ultimate Performance power plan in Microsoft Windows 10 and Windows 11

Now, you can navigate to the power plan page as described in the section above and enable the Ultimate Performance plan. If the page was already open, you may need to close it and open it again for the new plan to appear. However, even if you do everything right, this option no longer seems to work in Windows 11. Windows Terminal will show a success message, but the power plan won’t actually be added to your list.

How to Enable the Ultimate Performance Power Plan in Microsoft Windows 10

by Earendel | Sep 9, 2024 | How To News

Windows has plenty of features hidden away in old dialogs and registry keys. One of them is the fabled Ultimate Performance power plan, which, as the name implies, is intended to maximize performance on your PC. It’s mostly designed for workstation PCs, but you can enable it on any Windows computer with some tinkering.

The Ultimate Performance plan was added to Windows in 2018, and it builds off of the High Performance plan that ships with many PCs. It’s worth noting that a lot of PCs now include power modes in the Settings app, but those are different from the power plans in the Control Panel (we’re not sure why these are separate, either).

This power plan basically removes restrictions on power usage by certain components. For example, your CPU will always run at its maximum speed, reducing the tiny bit of latency that might occur when the processor boosts from a lower clock to a higher one. Similarly, a hard disk drive may not be allowed to stop spinning, ensuring that it’s always going full throttle and reducing latency when accessing files, since the drive no longer has to spin up. USB devices may also be blocked from entering a low-power state.

Overall, these measures should reduce the tiny bits of latency that can occur when the system needs to speed up for certain operations, but it shouldn’t affect overall performance for the vast majority of people. After all, your PC already runs as fast as it needs to when it needs to. By running full throttle at all times, you’re also using a lot more energy, which can kill the battery on a laptop, and result in higher energy costs for a desktop.

The Ultimate Performance plan is available in Windows 10, but it seems to no longer be available in Windows 11. In that case, your best bet is creating a custom power plan with similar settings.

The Ultimate Performance power plan can be enabled in the Control Panel, despite being a relatively recent feature. In order to enable it, follow these steps:

1. Open the Start menu and search for Control Panel. It should be the first search result.

2. In the View menu near the top right corner, change from Category to Small icons.

3. Click Power options

4. You’ll see all your power plans, but you may need to expand the Show additional plans section.

5. Select Ultimate Performance.

That’s all you need to do to enable this plan… Or it would be, if the plan was actually available. Unfortunately, on most PCs, and especially on laptops, the Ultimate Performance power plan is hidden away so you can’t see it in this dialog. In that case, follow in our next blog post.
