new pc

recently got a new pc asus,running windows 8. i wasn't happy with the way the 1tb hard drive had been partitioned, so having a legit copy of win 8 i thought i would reformat. when it gets to the reformat stage a message appears[ hard drive locked please unlock to continue] i have admin rights . but it will not unlock.been all over the web with no luck. hoping someone can help

Bit Locker maybe? Booting from install media or running setup.exe from Windows? Installing Windows 8.0 or 8.1? You can get Windows 8.1 from here, Create installation media for Windows 8.1 - Windows Help that will use Windows 8.0 and Windows 8.1 keys, even embedded OEM keys.

Have you created a recovery drive in case this process goes south for you?

1. Does the disk show as 'encrypted' in disk management.

2. Is your new PC an Instant Go device. Check in command prompt with this command: powercfg /a -- If it says Standby (Connected), then it is Instant Go.

3. Instant Go decryption instructions you can find in my little tutorial.
