Support Article - Windows 10 Installation Error cannot be installed to this disk

In some cases when trying to reinstall Windows 10 from a USB memory stick you will get the error

'Windows can't be installed on drive 0 partition 1'

Even when trying to install to a valid partition.

This is nothing to worry about and quite simple to fix

You will just need to clear the existing partition before you can recreate it and use the space again

In the above example with a 512gb SSD  the Drive we need to fix is drive 0

Most of our customers opt for a small SSD & a large HDD

Usually 256gb SSD with 1tb HDD

or 512gb SSD with 2tb HDD

or 128gb SSD with 500 HDD

So if you not sure check your original order if it says

1TB+256GB then you have a 256gb SSD

The SSD is usually where we install Windows 10 to and usually the SSD is Drive 0

First thing to try is simply select the partition and then press delete underneath

Click to acknowledge wiping of existing data 

Then if successful choose unallocated space to install to

However you might get an error unable to delete at this point

so

Reboot & Boot from your Windows 10 USB memory stick again

In some cases you may need to turn the PC off completely then power it back on again (cold boot), with the USB stick inserted

After initial screen, select Repair your computer , not Install now

Select Troubleshoot, 

And select Advanced Options

Select Command prompt

You should now be looking at a black screen where you can type commands

Type 'diskpart' and press enter

Type 'list disk' and press enter

in the example picture above the disk we want is disk 0

So type 'select disk 0' and press enter

Type 'clean' and press enter  (will wipe all partitions from the target drive)

Type convert gpt & press enter

Then exit and exit, restart & start installation process again 

You should now be able to choose the section marked unallocated space to install to

Or if the above fails

Type 'diskpart' and press enter

Type 'list disk' and press enter

in the example picture above the disk we want is disk 0

So type 'select disk 0' and press enter

Type 'clean' and press enter  (will wipe all partitions from the target drive)

Type 'create partition primary' and press enter

Type 'active' and press enter

Type 'format fs=ntfs quick' and press enter

Type 'assign' and press enter

Type 'exit' and press enter

Type 'exit' again and press enter

Now, select the option to shutdown the PC

Reboot again with the USB stick inserted

Choose 'Install Now'

Now when you get to the partition selection screen you will be able to select the partition you just created.

Installation can now continue as normal.
