Step-by-Step Guide to Fix the Windows Installer Error 0x80300002
-
Check Your Boot Order
Enter your BIOS or UEFI settings during startup (usually by pressing F2, DEL, or ESC). Locate the boot sequence and verify that your installation media (such as a USB drive or DVD) is set as the primary boot device. -
Remove Unnecessary Drives
Disconnect all secondary storage devices before starting the installation. Presence of multiple disks can confuse the Windows Installer, especially if multiple partitions have operating systems or boot records. -
Format the Target Partition
If the target disk has previously had an OS installed or contains legacy filesystems, you should consider formatting it. During installation, press Shift + F10 to open the command prompt and use thediskpartcommand.

Update or Reinstall Storage Drivers
Using outdated or incorrect drivers can cause drive recognition problems. During Windows installation, select the option to load drivers. Insert a USB with the correct storage controller drivers for your motherboard and install them before proceeding. -
Use a Different USB Port or Installation Media
Your install media itself might be faulty or incompatible. Try recreating your installation USB using tools such as Rufus or the Windows Media Creation Tool. Also, plug the USB into a different port—preferably a USB 2.0 port. -
Disable UEFI or Enable Legacy Boot
Some older drives and operating systems may require legacy boot support rather than UEFI. In the BIOS settings, try toggling UEFI/Legacy BIOS compatibility and attempt installation again.
