If you have recently upgraded or replaced the hard drive for your MacBook or iMac, you will need to reinstall macOS onto it. This guide will show you how to install macOS High Sierra onto a blank hard drive.

Before you begin, you will need to create a bootable flash drive. This requires having access to a Mac currently running High Sierra, in order to be able to download the 7.7 GB High Sierra file in the App Store. You will so need an empty flash drive that can fit 5.4 GB. Before proceeding with the guide.

If, like me, you have already formatted the disk in the Windows operating system, you will probably encounter an error message when trying to select the new disk as the installation destination that warns you that the disk is not 'GUID partitioned', and that you should go to erase it with the Disk Utility application. The trick here is to go to the DU application, select the 'Show all devices' option in the top left drop-down menu and then select the root device for your disk, and not the individual partitions.

That is the one that you must delete, and for that root device, the DU application will show you the option to select the “GUID Partition Map” inside the Erase button window. Best regards!!
