HDD Detected by BIOS But Not Windows
"I have an SSD that I've been using for a while, but it's almost out of space now, so I got a new internal hard drive that I want to use in addition to my SSD. I plugged in the SATA and power cables and went into the BIOS to make sure it was hooked up correctly. Sure enough, it was listed in the BIOS just like it should be, but when I go into Windows, I can't find it. Not just in "This PC" no, I know it needs to be configured before it will show up there, but even when I go into Device Manager or Disk Management, it doesn't show up. What am I doing wrong?"
If the hard drive is recognized in BIOS but not Windows, it's time to get it fixed. In this post, you will learn how to troubleshoot the issue. Before you are going to learn the solutions, figure out the reasons.
Why Does My Hard Drive Show Up in BIOS But Not Windows
Most reasons would lead to this error. If it's detected in the BIOS but not in the OS, it's likely that the driver being used by the OS is not compatible with the drive. It's also possible that one drive is compatible with AHCI and the other with legacy IDE. When you enable AHCI, Windows ignores the IDE drive. Thus, when you enable IDE, you can boot from the IDE drive, but Windows will ignore the AHCI drive. Other reasons can also result in this error and they are listed below:
- Incompatible file system
- Drive letter missing
- Driver issues
- Damaged MBR...
