Causes for Windows Can't Be Installed to Disk Error

When you come across with "Windows cannot be installed to Disk 0 Partition 1" or "Windows is unable to install to the selected location" error while installing Windows, don't worry. 

Windows cannot be installed to Disk 0 Partition 1

Here are two possible causes that prevent you from installing Windows on the target disk:

1. The Target Disk Doesn't Support BIOS or UEFI Boot Mode

"Windows cannot be installed to this disk 0 partition 1" error usually happens when the Boot Mode or Boot List Option in the Bios settings is set to UEFI (Unified Extensible Firmware Interface), and the hard drive is over 2 TB (terabytes) in size. 

When it appears, you will not be able to install windows on your computer successfully. To get rid of this error and continue with Windows installation, you will need to convert the target disk 0 to MBR to GPT first. 

2. SAS Driver Issue or Corrupted MFT on the Target Disk

When the target hard drive contains SAS driver issue or corrupted Master File Table (MFT), Windows Partition Manager (partmgr.sys) will lose communication when changes are made on the partition.

If you attempt to install Windows Windows 10/8/7 using the internal SAS controller for the hard drives, you might get a "Windows cannot be installed to disk 0 partition 1" error message. 

So how to remove this error, and install Windows computer on your selected disk 0 partitions 1 effectively? Try the following fixes in both Part 1 and Part 2.

Part 1. Fix "Windows Cannot Be Installed on Drive 0 Partition 1" Error

When the "Windows cannot be installed to disk 0 partition 1" error occurs, you can fix it using DiskPart or EaseUS partition software. And you can follow either fix with the tutorial steps listed below to get rid of this error from your disk. Both two solutions are simple and easy. 

However, as the DiskPart CMD command will result in data loss on the disk, so we recommend you to try EaseUS partition software, a safer way as your first choice. 

EaseUS Partition Master allows you to fix the "Windows cannot be installed to disk 0 partition 1" error without losing data.
