How to install Windows 8.1 pro on MBR?
This setup is really frustrating. It just started working after switching to a different operating system—I tried before and it failed. [sIGH]
I believe I've identified the steps you need to take: 1) Turn on CSM and adjust all settings to Legacy OPROM. 2) Locate a method to disable secure boot if it's turned off. In my experience, clearing the secure boot keys resolved the issue—load the default keys if needed. 2a) After disabling secure boot, switch the OS type to 'Other OS'. Proceed with the Windows installation; if the drive display says a drive isn't found, power down your PC, flip the PSU switch (if present), disconnect the power cable, reconnect, and retry. You likely don’t need to modify BIOS settings, though some adjustments might be required. When the PC restarts, it will report an overclock failure—this appears to be a BIOS bug. My system handled it without problems. It prompts F1 during setup; press it to access the setup menu in BIOS. From there, boot into your Windows installation disk or USB drive, and the installation should proceed smoothly. Although I encountered occasional BSOD messages during setup, they’re not affecting performance now.
