I had already partitioned the drive and formatted it. However, it is when I try to install Windows 8 from my usb flash drive, I get that error message.
I had done some research, of course, and supposedly if the installed OS is Windows 7, then just clicking on the next button during installation (ignoring the error msg) should allow Windows 8 to install. However, that did not work.
Because as said, the old format of the drive is NTFS file structure.
Windows 8 wants a GPT file format structure on the drive.
Partition the drive, format that part of the drive to a Gpt format.
Start windows 8 install and select the partition of the drive you formatted to GPT file table, you created.
