Windows 10 slow boot on an SSD

“I cannot recall when this started but I know this is not normal for the kind of laptop I have. I have started to notice that my Windows 10 has been getting this behavior where after the boot up process, to be more specific after the windows logo disappears (that time in between) until you see the login screen is about 45 seconds. Used to, it wouldn't be more than 5 seconds. Thank you in advance to whichever wizard can help me with this problem.”

SSD Slow Boot Windows 10

To get your Windows 10 computer to boot at lightning speed, you might consider installing Windows 10 on an SSD. For a long time, SSD drives have consistently outperformed HDDs in boot performance. Typically, the normal boot time of an SSD is around 20 seconds, while an HDD is 45 seconds. But some people say that even if they set the SSD as a boot drive, it still takes a long time to boot Windows 10, like 30 seconds to 2 minutes!

How to Fix SSD Slow Boot on Windows 10

Windows 10 booting slowly on SSD is related to many reasons. If your computer and laptop are running lots of services, your SSD could take a long time. This issue is also related to your AHCI driver and graphics card as well as your power plan. Below I'll give you 8 actionable methods to help you fix Windows 10 slow boot on SSD.

Method 1. Enable AHCI and Update AHCI Driver

Advanced Host Controller Interface, or AHCI, is a technical standard for an interface that enables software to communicate with Serial ATA (SATA) devices. AHCI enables advanced SATA features, such as hot swapping and Native Command Queuing (NCQ).

NCQ optimizes how SSDs and hard drives handle data requests simultaneously, minimizes the movement of the read-write heads, and uses AHCI to speed up hard drive access times. On SSDs, NCQ improves the performance of transferring large files. You can try to enable AHCI and Update the AHCI driver to fix slow boot time of Windows 10 SSD.

  1. Go to Search on Windows 10, type regedit, and open Registry Editor.


  1. In the left panel of Registry Editor, browse to the key location below.


  1. In the right panel of the iaStorV key, double click on the Start DWORD to modify it. Type 0 for AHCI, and click on OK.
  2. Then type Device Manager in the search box and click the top result.
  3. Locate your AHCI driver, right-click it and choose Update driver from the menu.

Update Driver

  1. Then click on Search automatically for updated driver software. Windows will now try to automatically update your driver.

Method 2. Disable Ultra Low Power State (ULPS)

Ultra Low Power State (ULPS) is a sleep state that lowers the frequencies and voltages of non-primary cards in an attempt to save power. The downside of ULPS is that is can cause performance loss and some crossfire instability. If you enable this feature, it may cause Windows 10 to boot slow on SSD. To fix this problem, you can try to disable ULPS in Registry Editor.

  1. Go to Search, type regedit, and open Registry Editor.
  2. Then click Edit in the upper left corner of Registry Editor and select Find in the expanded menu. Enter EnableUlps and press Enter.


  1. Then double-click on EnableUlps and change its value to 0.

After doing this workaround, try restarting your computer, it should at least start up a little faster. If the SSD slow boot on Windows 10 problem still persists, try the solutions below.

Method 3. Change Power Options in Control Panel

Your power plan will also affect your startup time on SSD. If disabling ULPS doesn't help much with Windows 10 boot slow on SSD, you can try changing the power options in the Control Panel to reduce boot time.

  1. Go to Search, type power management, and open Power Management.
  2. In the Power Management window, choose the High performance plan.

Method 6. Uninstall Your Graphics Card Drivers

Windows 10 SSD slow boot problem may be related to your graphics card. Some users have reported that they get stuck on a black screen when trying to start Windows. To fix this issue, users are suggesting to uninstall your graphics card drivers from your PC. To do that, follow the steps below.

After uninstalling the driver, check if the problem is resolved. And Windows will use the default driver after removing the driver. It is recommended that you update it as the default driver may not provide the same performance.

Method 7. Adjust/Increase Virtual Memory

On Windows 10, virtual memory is an essential component designed to remove and temporarily store infrequently use modified pages allocated in RAM to the hard drive. Using this approach, the system can prioritize faster physical memory for more frequent processes and applications, improving overall performance and preventing the device from locking up when the system runs low on memory.

According to users, you can fix SSD slow boot on Windows 10 by adjusting the amount of virtual memory. To adjust or increase virtual memory manually, follow the steps below.

  1. Type advanced in the Windows search box and select View advanced system settings from the result.
  2. Then in the pop-up System Properties window, click the Advanced tab at the top. Then click Settings under the Performance section.

System Properties Advanced Tab

  1. When the Virtual Memory window opens, uncheck Automatically manage paging file size for all drives and select your System drive.

Automatically Manage Paging File Size for All Drivers

  1. Select the Custom size option and set Initial size and Maximum size in MB. You can use any value for Initial size, but as for Maximum size use 1.5x or 2x the size of your RAM in MB. Click on Set and OK to save changes.
