Windows cannot be installed to disk 0 partition 1 is an error message you may encounter when you install Windows 7, Windows 8 or Windows 10. In this article, I’ll tell you why & how to solve this problem. At the same time, I’ll recommend you a partition software: AOMEI Partition Assistant.
Some people have problem with installing Windows 7 or Window 8. The installation stops on disk selection because of the error message "Windows cannot be installed to disk 0 partition 1..."
In order to explain clearly, I’ll show you an example. There are three partitions on disk 0: Disk 0 Partition 1 (100 GB System), Disk 0 Partition 2 (296 GB Primary) and Disk 0 Partition 3 (60 GB Primary).
When you selecting any one of them, you will get the message "Windows cannot be installed to Disk 0 Partition n".
★ On Partition 1 (System), the details are:
Windows cannot be installed to this disk. The selected disk is of the GPT partition style. Windows cannot be installed to this hard disk space. The partition is an EFI system partition (ESP).
★ On Partition 2 (Primary), the details just say:
Windows cannot be installed to this disk. The selected disk is of the GPT partition style.
★ On Partition 3 (Primary), the details say:
Windows cannot be installed to this disk. The selected disk is of the GPT partition style. Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS. Windows cannot be installed to this hard disk space. The partition is of an unrecognized type.
It can be upset when you cannot install Windows with the “Windows cannot be installed to disk 0 partition 1” note. In fact, every error message has tips behind it.
