One of the most aggravating tech issues is a slow to boot computer. In most cases, it is not a serious problem. Some startup programs, a full storage, wrong boot settings, or an old hard drive are some simple reasons why your PC, which normally starts up fast, can become a crawling sloth.

This guide will tell you why your computer is taking too long to boot, how to diagnose the problem, and how to make it boot faster without spending hours troubleshooting.

1. Why Does My Computer Take So Long to Start Up?

Following are the most frequent causes of a PC startup slow problem:

Too Many Startup Programs

There are lots of apps that start automatically during Windows startup. Every startup app you have will extend the time that Windows takes to boot.

Accumulated Temporary Files and System Junk

Temporary files, logs, cache files, and leftover installation data are all things that Windows accumulates over time. All this junk can impact the performance of your startup and responsiveness.

Slow Hard Drive

If you are running a traditional hard disk drive, the startup time may be quite slower than that of running an SSD. One of the biggest reasons for a computer to boot slowly.

BIOS or UEFI Delays

In some cases, the delay occurs even before Windows begins to load. Long BIOS startup times can be caused by USB devices, hardware checks, outdated firmware or boot order issues.

2. Check First: Analyze the "Last BIOS Time"

Before trying fixes, determine where the delay is happening. Windows includes a useful metric called Last BIOS Time in Task Manager.

  • Right click anywhere on your taskbar and select Task Manager.

  • Click Startup apps tab. Check the upper right corner of the window. A stat called Last BIOS time will appear.

The BIOS time is the hardware initialization time. In this phase, with a modern Solid State Drive (SSD) and a healthy motherboard, normal booting time is 5 to 15 seconds. If it takes more than 20-30 seconds, then the motherboard is doing a hardware check, or you need to adjust your BIOS settings.

3. How to Fix Slow Startup on Windows 11/10?

Now let's take a look at five simple ways to speed up your computer.

Option 1: Disable Unnecessary Startup Programs

This is the simplest hack to make computer faster. There are a lot of apps that run in the background without you knowing from the moment you boot up your PC.

  • Press Ctrl+Shift+Esc to open the Task Manager. Navigate to the Startup apps section.

  • Review the Startup impact column. Pay attention to applications rated as High or Medium.

  • Right click an app that you do not need at the moment (Discord, Steam, cloud storage apps) and click the Disable option.

Option 2: Clean Up System Junk and Temporary Files

Windows gets a lot of junk files over time. Regular cleaning can help improve system responsiveness and minimize start-up delay. This can be done easily using 4DDiG Partition Manager and its Windows cleaning feature.

  • Download and launch the 4DDiG Partition Manager on your PC. Go to Windows Clean section in the main interface panel. Next, click the Scan button.

  • Check out the detected junk items, and click Clean to remove the junk items safely.

    select items to clean
  • Once the cleanup process is complete, your computer can now boot more efficiently.

Option 3: Enable Windows Fast Startup

You can enable the Windows Fast Startup feature to improve the startup speed of your PC. it will save a part of the Windows kernel to a hibernation file to make the booting process quicker.

  • Press Windows key, type Control Panel and press Enter.

  • Click on Hardware and Sound > Power Options. Click on the power button settings option on the left side bar.

  • At the top, click the link: Change settings that are not available currently .

  • Select the Turn on fast startup (recommended) checkbox and save your changes.

This handy toggle can reduce your Windows slow boot up time by 50%.

Option 4: Optimize BIOS/UEFI Boot Settings

Sometimes, the delay starts even before Windows tries to boot. If your computer is slow to start up, the BIOS may be searching on drives that don't exist.

  • Turn your machine on and press the setup key (usually F2, F12 or Del) a few times to enter your BIOS.

  • Find a Boot Priority or Boot Order setting.

  • Move the main storage drive (the drive containing the Windows operating system) to the top in the list (position #1). This means that you don't have to look for other disc drives or first look for USB ports.

  • Select the Fast Boot or Quick Boot setting and turn it on (Disabled to Enabled). Click on Save and Close.

Option 5: Upgrade to an SSD

Software tweaks can only get you so far if you're attempting to speed up Windows startup. The best choice is to upgrade your boot drive to a Solid State Drive (SSD). Rather than hard drives, SSDs rely on flash memory, making a 60-second computer boot transform into a 10-second one. Here is the guide: How to Upgrade Hard Drive to SSD?

More FAQs about Windows Boot

1. Is a BIOS time of 13 seconds good?

Yes. A BIOS time of 13 seconds is generally acceptable and not considered slow for most PCs.

2. Does Fast Boot bypass the BIOS?

No. Fast Boot does not bypass the BIOS. It simply reduces some startup checks to help the PC boot faster.

3. If Fast Boot is turned on, how to get to BIOS?

Restart your computer, then press the BIOS key (usually F2, Delete or Esc) as soon as the computer starts up. BIOS can also be accessed via Windows Advanced Startup settings.

⚡ Conclusion

If your computer is slow to start up, you may find it to be quite frustrating, however, there are many ways to resolve that issue. If your PC still isn't as fast as you'd like, an SSD can help a lot.
