This issue occurs when Windows 8 switches to UEFI install mode – on a non-compatible motherboard. This is commonly caused by multiple HDDs plugged in during boot. Follow the guide below to fix it.
- Unplug any secondary HDDs (Hard drives) from your computer and leave the operating system HDD in.
- Begin the installation again – the install should automatically change the install to master boot record.
- Once installed – turn computer off and plug your other HDDs in.
