How to Fix Error 0x80300024: Windows Installation Failed

Error 0x80300024 appears during Windows installation when the installer encounters a problem with the selected partition or disk configuration. This is a common error when installing Windows 11 from a USB drive.

Fix 1: Disconnect Other Drives

The Windows installer can get confused when multiple drives are connected. Shut down your computer, disconnect any external hard drives, USB drives, and secondary internal drives. Leave only the drive where you want to install Windows connected. Try the installation again.

Fix 2: Delete and Recreate the Partition

During installation, when you reach the partition selection screen, delete all existing partitions on the target drive until you have unallocated space. Click New to let Windows create the necessary partitions automatically. This ensures the partition structure is compatible with Windows 11 requirements.

Fix 3: Check BIOS/UEFI Settings

Error 0x80300024 can occur if your BIOS settings are incorrect. Enter BIOS (usually F2 or Delete during startup) and ensure these settings: Boot mode set to UEFI (not Legacy), Secure Boot enabled, and SATA mode set to AHCI (not RAID or IDE). Save changes and try the installation again.

Fix 4: Recreate Installation Media

A corrupted USB installation drive can trigger this error. Use the Windows Media Creation Tool to create a fresh USB drive. Format the USB as FAT32 and ensure you use a USB 2.0 port if USB 3.0 ports are causing issues. Try a different USB port or drive if problems persist.
