Windows 10 Slow to Boot & Run After Clone
An SSD is well-loved by many users because of its excellent reading & writing performance. After purchasing one solid-state drive (SSD), they choose to clone the old HDD to the new SSD for an upgrade, avoiding reinstalling Windows 10. However, a common issue comes up – Windows 10 slow after clone. Perhaps you are also one of the victims.
To be specific, when booting Windows 10 from the cloned SSD, the startup time takes longer. Then, the PC runs slowly to load programs and handle multiple tasks. Since then, the computer performance has been extremely slow.
Why is Windows 10 slow to boot after clone or is Windows 10 lagging after cloning to SSD? It may stem from an outdated graphics card driver, insufficient Windows drive storage space, incorrect SSD settings, etc. Fortunately, you have a great chance to solve the slow issue on the PC. Without further ado, get started now.
Tip 1: Speed up Windows 10
When it comes to a slow PC, the first one you should do is speeding up it using some ways. Here, we strongly recommend using the PC optimizer, MiniTool System Booster to boost the PC performance.
It is specially designed to optimize the system for peak performance on multiple fronts, for example, uninstall unwanted apps, clean up the PC, speed up RAM/CPU, disable startup items and resource-hungry processes, and more. Via these tasks, many system resources will be released including disk space, RAM, and CPU, making Windows faster.
In order to address Windows 10 slow after clone, get this PC tune-up software to have a try.

Step 1: Launch MiniTool System Booster to its main interface.
Step 2: Hit Deepclean > START CLEAN, which performs a deep scan to remove unnecessary clutter from your computer. Then, do as the prompts say. In the case of Windows 10 slow after clone, using this feature to run some cleanup tasks will free up much disk space and free up your RAM to speed up it.

Step 3: When confronted with Windows 10 slow to boot after clone, you had better go to Toolbox > Startup Optimizer to disable some startup items to reduce the startup time. In addition, hit Process Scanner to find and end memory-intensive background tasks to relieve stress, and tap on Advanced Uninstaller to uninstall unnecessary programs to free up some disk space to make Windows 10 faster.

Tip 2: Enable AHCI in BIOS
If Windows is slow after cloning HDD to SSD, you should enable AHCI in BIOS to gain the best SSD performance.
Step 1: Run Command Prompt with admin permissions.
Step 2: Type bcdedit /set {current} safeboot minimal and press Enter.
Step 3: Restart the machine and press a boot key like F2 or Del to enter BIOS and enable AHCI.
Step 4: Save the change and exit BIOS, then open Command Prompt as an administrator again.
Step 5: Execute the command bcdedit /deletevalue {current} safeboot, restart the computer and Windows will install the AHCI driver automatically.
Tip 3: Enable Trim for SSD
Trim is a command that allows the Windows OS to inform an SSD which data blocks are no longer used, and therefore can be erased to improve the SSD performance.
To do this:
Step 1: Open Command Prompt with admin rights.
Step 2: Type fsutil behavior query DisableDeleteNotify and press Enter. If you see DisableDeleteNotify = 0, it means Trim is enabled for your SSD. If not, run fsutil behavior set DisableDeleteNotify 0 to enable it.

Tip 4: Disable Disk Indexing
Indexing helps speed up Windows search on a storage device. But for SSDs, this feature makes no sense. So you can disable disk indexing in case of Windows 10 taking longer to boot after clone or Windows 10 lagging after cloning HDD to SSD.
Step 1: In File Explorer, right-click on the system drive and choose Properties.
Step 2: In General, untick Allow files on this drive to have contents indexed in addition to file properties.
Step 3: Save the change.

Tip 5: Don’t Defragment Your SSD
It is a good idea to perform the defrag task for HDDs. While for an SSD, defrag inversely damages the disk and downgrades the performance. Thus, remember to disable SSD defragmentation if Windows is slow after cloning HDD to SSD.

Step 1: Type defragment and hit Defragment and Optimize Drives.
Step 2: Tap Change settings, untick Run on a schedule (recommended), and click OK.

Tip 6: Run Another Cloning Software
Windows 10 slow after clone may appear due to the unaligned partitions, causing decreased performance. Thus, we recommend running another cloning software, MiniTool Partition Wizard, to re-clone your HDD to SSD. With it, you can tick the option of Align partitions to 1 MB when selecting the cloning option.
Get this partition manager and hit Copy Disk Wizard, then begin.
