If PC cannot boot anymore since hard disk is not recognized, you can install the software on another computer and connect this hard disk to that computer.

Hard Disk Drive Not Showing up in Computer

A hard disk usually consists of several partitions. If only one partition is not showing up after booting computer normally, you can check following reasons:

1. Partition was deleted by mistake
2. Partition table is corrupted
3. Partition is infected with virus


If you encounter this problem, you can go to Disk Management to see if the partition shows there. If the partition got deleted, it shows as unallocated space under Disk Management. However, if partition table is corrupted or got lost due to virus infection, you may need to repartition hard disk or rebuild MBR.

If hard disk is not recognized by BIOS settings, the reasons might be:

1. Hard disk is damaged. If this is the reason, you may need to replace the damaged hard disk with a new one.
2. There is something wrong with hard disk interface or power connector
3. The interface of motherboard has problems or the motherboard is corrupted
4. The hard disk is disabled in BIOS setting.


If BIOS cannot detect hard disk, you can press F2 (it is different on various computers) to enter BIOS setup to check and fix the problem.
