Format the drive.

Custom install / remove partitions / format drive.

Only have your C: drive hooked up when you install no other drives.

You may have to mount the drives on a working PC first.

Go to Control Panel -> Administrative Tools -> Computer Management

When the Computer Management application starts, in the left hand column select "Disk Management". Wait for Windows to populate the list in the middle column, bottom half.

If your BIOS detects the HDD but windows doesn't, it should appear in this list. Find the HDD in this list. All you should need to do now to get access to the drive is assign it a drive letter by right clicking the entry and selecting "Change Drive Letter and Paths". You can also reformat and repartition the drive using this application. Remember this tool in windows as it is the primary disk management tool for Windows OS's, and easily one of the most useful. So take note of it for future reference.

Just be aware, that if the drive is using a non-windows format such as Linux's Ext4, then windows will not be able to mount and use that partition. It can see the drive, (it can even cause hangs when booting windows while windows can take a long to time to figure out it can't use it before giving up)., it just can't use those partitions while in windows. So if you want to use HDD's that have those partitions on them, then you will want to repartition and reformat the drive in question.

Hope this helps.

That would work if he had Windows already installed, re-read his post, OP is trying to install Windows and the HDD don't show during Windows installation.

Try downloading the SATA drivers for that motherboard on your other PC, then copy the drivers in a folder on the USB drive that has the Windows installer.


When you're on the window to choose the drive click "load driver"



From there you should be able to browse ot the folder with the drivers and see the HDD. Good luck! :thumb:
