Fix Fast Startup Missing in Windows 11

If the “Fast Startup” option is missing from your Windows 11 Power Options, it’s usually because the feature is disabled in the Control Panel or your system doesn’t support it (e.g., you have an SSD or have hibernation turned off). The fix is to re-enable hibernation and then turn on Fast Startup in the Control Panel’s Power Options.

What Is Fast Startup?

Fast Startup (also called Fast Boot) is a Windows feature that reduces boot time after a shutdown. Instead of fully closing the kernel session and drivers, Windows saves a portion of the system memory (the kernel and loaded drivers) to a file called hiberfil.sys when you shut down. On the next power-on, Windows loads that file instead of starting everything from scratch, which can make booting noticeably faster.

It’s important to understand that Fast Startup only applies to shutdown, not to restart. A restart performs a full boot, which is why restarting often fixes issues that a shutdown+start doesn’t.

Why Is Fast Startup Missing in Windows 11?

There are several common reasons why the checkbox for Fast Startup doesn’t appear in the Power Options menu:

Hibernation is disabled. Fast Startup depends on hibernation. If hibernation is turned off, the option is hidden.
You have an SSD (Solid State Drive). Windows may automatically disable Fast Startup on systems with SSDs because the boot speed difference is minimal, and it can cause issues with certain drivers.
Group Policy or registry settings. Some IT administrators or power settings can disable the option.
You’re using a desktop with a specific power plan. Some custom power plans may not show the option.

How to Enable Fast Startup in Windows 11

Here are the steps to get the Fast Startup option back:

Enable hibernation: Open Command Prompt as Administrator (right-click Start > Terminal (Admin)). Type powercfg /h on and press Enter.
Open Control Panel: Press Win + R, type control, and press Enter.
Go to Power Options: Click on “Hardware and Sound” > “Power Options”.
Choose what the power buttons do: On the left sidebar, click “Choose what the power buttons do”.
Change settings that are currently unavailable: Click the blue link at the top that says “Change settings that are currently unavailable”.
Check “Turn on fast startup”: Scroll down to the “Shutdown settings” section and check the box next to “Turn on fast startup (recommended)”.
Save changes: Click “Save changes” at the bottom.

If the option still doesn’t appear after enabling hibernation, try the following:

Run powercfg /h /type full (instead of the default “reduced” type) to ensure full hibernation support.
Check your BIOS/UEFI settings – some motherboards have a “Fast Boot” option that can conflict with Windows’ Fast Startup.
Make sure your power plan is not set to “Ultimate Performance” (which sometimes hides the option).

Common Problems and Misconceptions

Many users confuse Fast Startup with hibernation itself. They are related but not the same. Hibernation saves the entire session (including open apps) and restores it exactly. Fast Startup only saves the kernel and drivers – it does not restore your open programs.

Another misconception is that Fast Startup works with Restart. It doesn’t. If you click “Restart”, Windows performs a full shutdown and boot, ignoring Fast Startup. This is intentional to ensure a clean state for updates and driver installations.

If you’re experiencing boot issues like “Windows isn’t loading correctly” or driver errors, Fast Startup is often the culprit. In that case, you may want to disable it rather than enable it.

Should You Use Fast Startup?

Whether you should enable Fast Startup depends on your hardware and usage:

If you have a traditional HDD: Fast Startup can significantly reduce boot time, so it’s usually beneficial.
If you have an SSD: The gain is minimal, and Fast Startup can cause issues with dual-boot setups (e.g., if you have Linux installed, it may not see the Windows drives properly).
If you use BitLocker or other encryption: Fast Startup can interfere with the encryption process on boot, so it’s often disabled by default.
If you’re troubleshooting: Disabling Fast Startup is a common step in fixing boot problems, so it’s better to turn it off temporarily.

How to Disable Fast Startup (If You Need To)

If you want to turn it off, simply uncheck the box in the same Power Options menu. If you want to completely remove the hibernation file (which can be large), run powercfg /h off in an elevated Command Prompt. This will also remove the Fast Startup option entirely.

Note that disabling hibernation will also remove the ability to use “Hibernate” in the Power menu, and it may affect other features like “Windows Update” fast boot.

Alternatives to Fast Startup

If Fast Startup is missing or you don’t want to use it, here are alternatives to speed up boot:

Enable UEFI Fast Boot: In your BIOS/UEFI settings, look for “Fast Boot” or “Quick Boot”. This skips some hardware checks and can speed up POST.
Reduce startup programs: Use Task Manager > Startup apps to disable unnecessary programs that launch at boot.
Use Sleep instead of Shutdown: Sleep resumes almost instantly and uses very little power. It’s not the same as Fast Startup, but it’s faster for day-to-day use.
Update your drivers and BIOS: Sometimes outdated drivers cause slow boot times.

Frequently Asked Questions

Why is Fast Startup missing even after I enabled hibernation?

If you’ve run powercfg /h on and the option still doesn’t appear, check if your system uses a “reduced” hibernation file. Run powercfg /h /type full to switch to full. Also, verify that you’re looking in the right place – the option is under “Shutdown settings” in the “Choose what the power buttons do” page, not in the main Power Options window.

Does Fast Startup work with SSDs?

It can, but the boot time difference is often negligible compared to HDDs. Some users report that Fast Startup on SSDs can cause issues with certain hardware (like external drives not being recognized). If you have an SSD, you may not need it at all.

Will Fast Startup affect dual-booting with Linux?

Yes. Fast Startup can leave the Windows filesystem in a “hibernated” state, which Linux may not be able to mount properly. It’s recommended to disable Fast Startup if you dual-boot to avoid data corruption.

How do I know if Fast Startup is currently enabled?

Open Command Prompt as Administrator and run powercfg /a. It will show whether hibernation is available. To see if Fast Startup is enabled, check the checkbox in Power Options – if it’s checked, it’s enabled. You can also run powercfg /lastwake to see if the last shutdown used fast startup (it will show “Wake Source” as something else).

Can Fast Startup cause problems with Windows Updates?

Yes, sometimes. Because Fast Startup doesn’t fully shut down, Windows Updates may not install correctly. If you’re having update issues, try disabling Fast Startup and then restarting (a full restart, not shutdown).
