Computer Install system error prompt: Invalid switch fmount how to do?

Install the system we often encounter error prompts: invalid switch fmount, resulting in the original computer system can not go, also installed not on the current system, very distressed, this article to share my solution, of course, not all the problems are the solution.

1, when we install the system, will appear as shown in the picture. So what's the problem? I was checking to see that my system was not selected by default C disk (System disk), pointing to a non-existent small partition, so can not read the hard drive, I was through the partition tool to point to C disk and set as active disk.

2. Insert the U disk with PE and start the computer. (As for U disk PE Startup disk is not elaborated here, many online as shown), select "Run WinPE" (each PE here name is not the same), refers to the line installation program, installation completed automatically start the computer.

3, the operation of Diskgenius, performing disk finishing operations, the extra disk deleted (usually the computer can not see the disk, sometimes appear like dozens of trillion disk, completely useless, delete does not affect).

4, format the C disk, and then set the C disk as the active partition.

5, run Onekey continue to install my system.

6, click to restart the installation can be.
