Scenario: HDD/SSD Shows Up in BIOS but Not Windows
Hello, I have a hard drive that is only showing up in BIOS, and is nowhere to be found in Windows, not in Disk Management and not in Device Manager. I have it plugged into the first SATA port on my Asus ROG Strix B-560 A Gaming WiFi Motherboard if that matters. If anyone who might know how to fix this please do.www.reddit.com
A hard drive, also known as a hard disk drive (HDD), is a physical data storage device that can be used to store various types of data, including operating systems, applications, documents, music, videos, and photos. However, sometimes you may find that the HDD/SSD shows up in BIOS but not Windows. This problem prevents you from accessing and managing data on it. Here are several ways to help you fix the issue.
Common Causes of HDD/SSD Not Showing Up in Windows
When a hard drive is recognized in BIOS but not in Windows, the problem may be related to how Windows detects or manages the disk. Common causes include:
- The disk is offline, uninitialized, or has unallocated space.
- The drive has no drive letter or the assigned letter conflicts with another volume.
- The disk driver is damaged, outdated, or installed incorrectly.
- The partition table or file system is damaged or incompatible with Windows.
- The BIOS storage mode is incorrect for the installed drive.
- The drive has a hardware or firmware problem that prevents Windows from detecting it properly.
Recover Data From Unrecognized Hard Drive in Advance
If the hard drive contains important files, recover them before trying to initialize, format, or otherwise modify the disk. These operations may change the disk structure or file system and can make data recovery more difficult.
MiniTool Power Data Recovery is a hard drive recovery software that can help recover existing, lost, or deleted files from supported storage devices.
If Windows cannot access the drive but the software can detect it, you can scan the disk and recover the needed files to another storage device.
Step 1: Connect the disk to your computer and click on the following button to download MiniTool Power Data Recovery software.

Step 2: Launch the software and scan the partition or disk in the main interface.
The Logical Drives tab comes into your sight by default. This section includes all the existing, lost, and deleted partitions. Next to it, the Devices tab contains all the disks connected to your computer. There are two options you can choose.
- The first is to scan the partition where the important data are stored. To do so, you are expected to move your cursor to the targeted partition under the Logical Drives tab and click on Scan to scan for data.
- The other is to scan the whole disk one time. To do so, you are supposed to put your cursor to your disk under the Devices tab and click on Scan in the end to start scanning.
Step 3: Find the required files using various features.
The scanning process will take some time. To obtain the best outcomes, it is best to wait patiently for it to complete. Once it ends, all the files are listed by their paths under the Path tab, which may take some time to navigate to desired files. To enhance user experience, the recovery tool provides several features on the scan results page to help locate specific files more efficiently.
- Type: As you can tell from the name of this feature, it classifies files into types including documents, audio, videos, pictures, and more.
- Filter: Compared with Type, it can further narrow down the file scope. With four classification criteria – file type, file size, file category, and file modification date – this feature allows you to set filter conditions based on your needs.
- Search: Compared with the first two features, this one is more targeted. What you need to do is type the keywords of the file name in the search box and press Enter to filter out unnecessary files.
Step 4: Preview the file to check its accuracy using the Preview feature.
After all the target files are displayed, you can preview them before saving them to avoid wasting free recovery capacity. Double-click on the file or select it and click on the Preview button.
Step 5: Save the selected files to a new location.
After confirming the files, select them all and click on the Save button. In the directory window, you have to choose a new place for the recovered files. Finally, click on the OK button to get started.
When the Recovery Completes window shows up, you can close the window and go to the selected directory to check if files are here.
How to Fix Hard Drive Shows Up in BIOS but Not Windows
When the data is recovered successfully, let me show you how to fix the problem of “hard drive shows up in BIOS but not Windows”.
The right fix depends on what Windows detects. Check the drive’s status first, then choose the corresponding solution below.
| Drive Status in Windows | Recommended Action |
| Disabled in Device Manager | Enable the drive |
| No drive letter | Assign a drive letter |
| Offline | Bring the drive online |
| Unallocated | Create a new volume |
| Not Initialized | Initialize it only if it is new or empty |
| Not detected in Windows | Check Device Manager, drivers, BIOS settings, and hardware |
Way 1: Check if the Drive Is Enabled
If the hard drive is listed in Device Manager but cannot be accessed in Windows, it may have been disabled. Check the Disk drives category and enable the drive if necessary.
Step 1: Right-click on the Start icon and choose Device Manager.
Step 2: Click on the small arrow in front of Disk drives to expand it.
Step 3: Find and right-click on the drive to see if it is disabled. If it is, click on Enable device to enable it.
Way 2: Assign or Change Drive Letter
If the hard drive appears in Disk Management but is missing from File Explorer, it may not have a drive letter or may be using a conflicting letter. Assigning a new drive letter can make the volume accessible in Windows.
Step 1: Right-click on the Start button and choose Disk Management.
Step 2: Find and right-click on the hard drive to choose Change Drive Letter and Paths.
Step 3: There are two options you can choose based on your situation:
- If the hard drive has no drive letter, click on Add to add one.
- If the hard drive has one drive letter that is the same as another partition, click on Change to change one.
Step 4: Select Assign the following drive letter and choose a letter from the drop-down menu.
Step 5: Finally, click on OK > Yes to confirm the change.
Way 3: Initialize and Partition the Hard Drive
If the drive is new or contains no important data and appears as Not Initialized in Disk Management, you can initialize it and create a new volume.
Step 1: Press the Win + X keys and choose Disk Management.
Step 2: Right-click on the drive and select Initialize Disk.
Step 3: In the new window, you will see two partition styles: MBR and GPT. Choose one according to your needs and click on OK.
After initializing, you need to partition the drive.
Step 1: Right-click on the unallocated space and choose New Simple Volume.
Step 2: Click on Next to choose a drive letter and then click on Next to go to the next page.
Step 3: Under the Format with this volume with the following settings section, choose the file system, allocation unit size, and volume label. Then click on Next > Finish.
Way 4: Update the Disk Driver
If Windows detects the drive but cannot access it correctly, an outdated, corrupted, or incorrectly installed disk driver may be responsible. Updating the driver can help Windows communicate with the storage device properly.
Step 1: Type Device Manager in the Windows search box and press Enter.
Step 2: Find and double-click on the Disk drives to expand it.
Step 3: Right-click on your drive and choose Update driver.

- bootrec /fixboot
- bootrec /scanos
- bootrec /rebuildbcd
Way 7: Format the Hard Drive
If other troubleshooting methods fail and the drive is still accessible through Disk Management, formatting may resolve certain file system problems. However, formatting deletes the data on the selected volume, so recover important files first if you still need them.
Use Disk Management
Step 1: Open the Disk Management and right-click on the drive to choose Format.
Step 2: Type a new volume label, and choose the file system and allocation unit size.
Step 3: Check the Perform a quick format option and click on OK to start formatting.
Use MiniTool Partition Wizard
If Disk Management fails to format the drive, you may need a professional tool to complete the task. MiniTool Partition Wizard has the ability to manage disks and perform various disk management tasks, including formatting drives. Here are the steps.
Step 1: Download MiniTool Partition Wizard software by clicking on the green button.
