Win10 Not Booting: Hardware Upgrade with HDD and New SSD

Introduction

Upgrading your hard drive from a traditional HDD to a new SSD is a common practice among PC enthusiasts and professionals. This process not only enhances the system's performance but also ensures better reliability and faster boot times. However, there are instances where the system may fail to boot after the upgrade. In this article, we will discuss the possible reasons for this issue and the steps to resolve it.

Historic System State: HDD (Win7), Created 100MB Hidden System Partition Beginning Disk

Before proceeding with the upgrade process, it is essential to understand the current system state. In this scenario, the PC has an operating system installed on a traditional Hard Disk Drive (HDD) running Windows 7. The HDD contains a hidden system partition of 100MB, which is created at the beginning of the disk.

Upgrade Process: Installing New SSD and Win10

The upgrade process begins by installing the new SSD in place of the HDD. Once the SSD is installed, the new operating system (Win10) is installed on it. The installation process creates a new system partition on the SSD, which is used to boot the system.

Boot Issue: Win10 Fails to Boot from New SSD

After the upgrade process, the system fails to boot from the new SSD. This issue could be due to several reasons, including:

Incorrect BIOS settings:
Unrecognized SSD:
Missing or incorrect system files:

Solution: Resolving the Boot Issue

1. Check BIOS Settings

The first step is to check the BIOS settings to ensure that the system is set to boot from the new SSD. To do this:

Restart the system and press the key to enter the BIOS settings (F2, F10, or DEL key).
Navigate to the Boot Order settings and ensure that the SSD is listed first.
Save and exit the BIOS settings.

2. Check SSD Recognition

If the system still fails to boot, check if the SSD is recognized by the system. To do this:

Restart the system and press the Windows key + R to open the Run dialog box.
Type diskmgmt.msc and press Enter.
Check if the SSD is listed in the Disk Management tool.

3. Check for Missing or Incorrect System Files

If the SSD is recognized, but the system still fails to boot, there might be missing or incorrect system files. To resolve this:

Create a Win10 installation media using a USB drive or a DVD.
Boot the system from the installation media.
Select the "Repair your computer" option.
Select the "Troubleshoot" option and then "Advanced options".
Select "Command Prompt" and run the following commands:


 bootrec /rebuildbcd

 bootrec /fixmbr

 bootrec /fixboot

These commands will repair the boot files and rebuild the boot configuration data.

Upgrading from a traditional HDD to a new SSD is an excellent way to enhance system performance and reliability. However, there are instances where the system may fail to boot after the upgrade. In this article, we discussed the possible reasons for this issue and the steps to resolve it. By following the steps outlined in this article, you should be able to boot your system from the new SSD.
