Solutions to "Windows Cannot be Installed to Disk 0 Partition 1" Issue

Some people have problem with installation Windows 7 or Window 8. 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 take an example as the following:

You have three partitions on disk 0:

  • Disk 0 Partition 1 - 100 GB System

  • Disk 0 Partition 2 - 296 GB Primary

  • Disk 0 Partition 3 - 60 GB Primary

When you selecting any of them, you will get the boring 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.

And 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.

In fact, every error message has tips behind it. If your partition is GPT, you should ensure that your motherboard support UEFI/EFI, so system can boot from from GPT partition. Otherwise you have to convert GPT to MBR. GPT is one of partition styles, NTFS is one of file system. If it asked you installed to a NTFS partition, you can select NTFS when you formatting it, you can also try to convert FAT to NTFS.

The main problem is many users don’t know their machine’s partitions very well, so they have to deal with every different question time after time. Thus spend lots of time. So, is there any solution help you solve all of them at one time? Yes, some geeks have already found out practical methods and post them on Internet.

At first, let me tell you that most of them who come across these problems is due to they want re-install Windows or install a second OS as dual boot system. That is to say, their partitions are used before.

Solution 1:

If there is no reason to keep these partitions, you can remove them by using Windows Disk Management tool on the installation disk as follows:

Left click a partition to highlight it. Click on the blue link “Drive options (advanced)”. Select the “Delete” option.

Repeat this for each partition listed.

When done, you should see just 1 entry showing as “Disk 0 Unallocated space”

Click the “Next” button to install Windows 7 continuely.

Be aware that Windows 7 will also create a hidden “System Reserved” partition of around 100Mb which contains the boot files and recovery environment. Backup your important things before deleting.

Solution 2:

At the screen when it ask you to choose which drive to install Windows on, press Shift+F10 and a DOS window would open.

  • Type: diskpart

  • Type: list disk (you should see only Disk0)

  • Type: select disk 0

  • Type: clean

Close the DOS window, click on Refresh, select the disk that is listed, and click Next.

Above mentioned Disk management and Diskpart are two different tools. But they have something in common: they both work on drive and partition. If you think you can only use these two tools to do partition options when your OS runs normally, you are wrong. Thanks to the development of software technology, there are some third-party partition software. Here I recommend you try AOMEI Partition Assistant. Professional thing should be done with professional tool.
