My Acer aspire v5 laptop running on windows 8 when booting it says "Operating System not found". When I enter BIOS setting, in the information tab sometimes my HDD model and name won't show and then sometimes it does.

I have tried using repair my computer on my windows 8 CD installer and all of the options in "Advance options" I tried but nothing worked. Troubleshooting did not work also.

I have tried formatting using the installer but when I reach the partitioning step it freezes.

Please help. I don't care if my laptop will be formatted just want get it work again >_<
 
You can try the following steps, if you haven't already. However, if it doesn't work to reinstall the system, then there may be problems with the drive itself. Which would mean it would need replacing.

How To Fix "Operating System Not Found" or "Missing Operating System" error.

1. You will need your Windows OS (Operating System) CD or bootable Windows OS USB device.
2. Connect the bootable USB device or insert the CD into your computer.
3. Now use the "F2, F12 and Delete" keys enter BIOS setup.
4. Click "Repair Your Computer" below the "Install Now" button.
5. While you are in the "Repair Your Computer" open "CMD" (Command Prompt).
6. When you are in "CMD" type “diskpart” then type “list volume”.
7. Next you will be in "list volume". All volumes should be shown.
8. Find your system volume, where the windows are installed and then type “select volume ###“(system volume C) shows on CMD. Ex. select volume 3.
9. After you have selected the volume, type “ACTIVE“. Your system partition is active now.
10. Now type ”exit” to leave diskpart and then type ”exit” again to close CMD.
11. That’s it now RESTART your computer.

This should work, if you follow the steps correctly.
