Dynabook not start after SSD replacement: How to Fix?

Part 1: Reasons why Dynabook stopped booting after SSD replacement

There are five possible reasons why your Dynabook won't start after replacing the SSD. We will explain them step by step, so please refer to them.

Cause 1: SSD is not recognized

Booting may fail if the computer does not recognize the SSD. This could be due to a loose connection, a bad connecting cable, or even an issue with the SSD itself.

Cause 2: Boot partition not created on SSD

In order for your computer to start up, you need a boot partition on your SSD. A boot partition is a partition for data necessary for the boot process of PCs such as Dynabook. Partitions separate data and allow different functions to be performed.

In other words, if a boot partition is not created on the SSD, the computer will not be able to boot properly.

Cause 3: The boot partition has the wrong file system

Even if you have a boot partition, your computer may not boot if the file system is incorrect. For example, the boot partition's file system is FAT32 when it should be NTFS.

Cause 4: Boot device in BIOS is not set correctly

BIOS is an abbreviation for "Basic Input Output System". It is a program for controlling computer devices (keyboard, display, etc.). The BIOS settings that specify which device to boot from when starting your computer may be incorrect.

If the SSD is not properly set as a boot device, your computer will not boot properly from the SSD.

Cause 5: SSD is malfunctioning

If the SSD itself has a physical failure, it will not be able to boot properly. Possible causes of failure include bad sectors, controller problems, poor contact, and impact from dropping.

Part 2: What to do if Dynabook no longer boots after SSD replacement

If your Dynabook no longer boots after replacing the SSD, there are four ways to deal with it. Use this as a reference when your computer does not start up properly.

Solution 1: Enable SSD in BIOS and set boot device to SSD

You can enable SSD in your Dynabook's BIOS settings and set it as your preferred boot device. After connecting the SSD to your computer, follow the steps below.

• Restart your computer and press "F2", "F8", "F11", or "DEL" to enter the BIOS.
• On the setup screen, turn on or enable the SSD.

• Save changes and exit BIOS.

  After rebooting after the above steps, the disk management tool will show the connected disk and you can enable the SSD and make it the boot device.

  *You can also open the same screen by pressing the "Win" + "R" keys at the same time and entering "diskmgmt.msc".

• Click on the file you want to delete, such as SSD, and press the cross mark. *Can also be executed by right-clicking.
• After deleting, right-click and click "New Simple Volume".
• You can recreate the volume by following the on-screen instructions.

Solution 4: Replace the Dynabook SSD

If other solutions do not work, there is a high possibility that there is a problem with the SSD itself. Buy a working SSD and replace it.

In addition to the above solutions, you can also perform a clean install to solve the problem of not booting due to SSD replacement.
