Fix: Windows Installation Fails With Error Code 0x80300024

If you’re seeing Error Code 0x80300024 during the Windows installation process, it usually appears on the screen where you choose a drive to install Windows.

What Causes This Error?

This error typically appears when:

• Multiple hard drives or partitions are connected, confusing the installer

• There’s not enough available space on the selected drive

• The drive has a previous failed installation or formatting issue

• The drive is connected to a secondary SATA port or controlled by a non-primary controller

How to Fix It

1. Unplug All Drives Except the One for Installation

• Disconnect all other internal and external drives (USB sticks, secondary HDDs or SSDs)

• Only leave connected the drive you want to install Windows on

Then restart the installation process.

2. Use Diskpart to Clean the Target Drive (Will Erase Data)

If you want a full reset of the target drive:

1. At the Windows setup screen, press Shift + F10 to open Command Prompt

2. Type the following commands one by one:

diskpart

list disk

select disk X ← (replace X with the number of the drive you want to use)

clean

exit

1. Close the Command Prompt and click Refresh in the installer

2. Select the unallocated space and click Next

Note: This will permanently erase all data on the selected drive.

3. Change SATA Port or Controller Setting in BIOS

• Enter BIOS/UEFI (usually F2, DEL, or ESC at startup)

• Ensure your drive is connected to the primary SATA port

• Try changing the SATA mode from RAID to AHCI or vice versa

• Save and exit BIOS, then try installation again
