I have read the entire conversation between you and the previous Expert (Louie).
The problem you are experiencing is caused by the corrupted Windows boot files. The usual repair methods won't work, so you will need to re-install Windows. You can do that using the built-in ASUS recovery manager or using a Windows 10 disk.
To access the built-in ASUS recovery manager, power on the laptop and immediately keep pressing the F9 key. It will start the ASUS recovery manager where you can choose between several options - "Recover Windows to First Partition Only" or "Recover Windows to Entire HD". The first option will delete only the system (C:) drive and re-install Windows, while the second option will delete all drivers and re-install Windows. In case you have several partitions created, for example system (C:) for Windows and data (D:) for data, you can choose the first option to delete only the C: drive, while keeping the D: drive. That will re-install Windows without deleting your data on another partition.
Alternatively, you can re-install Windows using a Windows 10 disk. If you don't have one, there is a way to download the Windows 10 disk image file from the Internet and burn it onto a blank DVD using another computer. You can do that in case the built-in ASUS recovery manager doesn't work.
So, when you come back, you can check if pressing the F9 key will bring the built-in ASUS recovery manager.
