After upgrading the hard drive it’s not detected by the laptop BIOS. The hard drive doesn’t appear in the BIOS.
1. Hard drive is not connected properly.
2. Hard drive not supported.
3. Bad hard drive.
Possible troubleshooting steps and repair solution:
1. Make sure the hard drive is properly connected to the motherboard. Try reconnecting the hard drive. Find out if the hard drive appears in the BIOS after reconnecting.
2. Enter the BIOS setup menu and load default settings. Safe settings and restart the laptop. There is a chance that your new hard drive will be detected after that.
3. If you installed a larger hard drive, make sure it’s supported by the laptop. Some older laptops will not support large hard drives. In some cases, a larger hard drive will be supported after you upgrade laptop BIOS to the latest version.
Upgrade the BIOS if needed.
4. Try installing the old hard drive. If the old drive is detected but the new one is not, it’s possible that your new hard drive is defective.
