B. Backing Up Important Data

Migrating the OS from one drive to another could cause potential data loss. To avoid the inconvenience, you must create a backup of all your existing data and save it in an external drive.

If your backup part is done, let's physically remove the old HHD and install the SSD. Here are the quick steps to install and initialise SSD.

#1. Install SSD

Note* The steps may differ slightly according to the model of your computer.

Step 1: Turn off the laptop and remove all the cables.

Step 2: Hold the laptop upside down and remove the base cover.

Step 3: Detech the battery and hold the power button for 20 seconds. It will drain all the electric charges. 

Step 4: Find the HDD and unscrew it from the motherboard. Avoid applying unnecessary force.

Step 5: Gently remove the hard drive and insert the new SSD.

Step 6: Plug the drive directly and screw it on the system board. 

Note* You may need to attach the SSD with a SATA cable if you are using an older laptop. 

Step 7: Attach the battery and base panel.

#2. Initialize SSD

Once the physical installation is completed, initialize the SSD to the same partition style as the OS disk using disk management. Here are the quick steps:

Step 1: Hit the power button to reboot your computer.

Step 2: Press "Win + X" and select "Disk Management" from the list. 

Step 3: You will encounter the list of all the connected drives. Navigate the SSD and right-click on it.
