{'Internet Connection': '- For Wifi connection, go to the bottom-right corner of the screen, click on the Wifi icon, and select a Wifi connection.'}
{'Ethernet Connection': '- If using an Ethernet cable, simply plug in the Ethernet cable, and DHCP will automatically configure the network connection details.'}
{'Step 3': 'Step 3: After establishing the Internet connection, on the OS X Utilities window, select Reinstall OS X.'}
{'Step 4': 'Step 4: Choose the target drive to reinstall OS X (usually Macintosh HD, but it may vary for each user). If your Mac has FileVault password set up, select Unlock and enter the FileVault encryption password before proceeding with the next steps.'}

For example, in situations where Macintosh HD is stuck in the Trash and begins deleting system-level files, leading to the operating system missing crucial components for proper functioning.'}
{'Potential Solutions': 'Although the likelihood of facing such errors is low, you can use the system folder if SIP is disabled or when using root. This is applicable if the Mac's operating system boot partition is deleted or 'lost,' or if something unusual appears during startup (sometimes a folder with an X icon or a folder with a blinking question mark), or if the OS X installation is incorrect or faulty.'}
{'Important Note': 'Note that this method differs from a clean install, and it only reinstalls the currently running OS X version on the Mac (in this guide, it's El Capitan). In contrast, Internet Recovery will reinstall the integrated OS X version on the Mac (Yosemite). Clearly, each OS X version will vary, depending on the built-in options on the Mac, and the Mac is running which version.'}
