Yes, that's what you mean. Before installing the system, drive C has been formatted. If you have installed an operating system below WIN7 before, I suggest you use a USB flash drive to back up all the necessary data, repartition the computer and redo the system. You must pay attention to the fact that when partitioning, the hard disk format must be specified as gpt instead of mbr. Mbr is the format of operating system below win7, and gpt above win8. If you have a genuine system, you must have a genuine backup, so I suggest you call the official maintenance department and they will tell you how to restore the operating system online. It is best to install the system once under the guidance of professionals, and then install it yourself later.

If you use USB flash drive pe to install the system, you need to download a USB flash drive production tool. I suggest you use U Master two-in-one version. This tool is easy to use. You can choose the system image of autumn leaves system, corn system and green apple home, and search online and enter official website to download.
