Returning to OEM
Returning to OEM
To switch from your retail W8 Pro to your preinstalled OEM W7, first ensure you have the correct installation media. If the reinstall button in W8 shows missing files, verify your installation disk is valid and complete. You may need to perform a clean install or repair using the original OEM tools. If unsure, consult your system documentation or support for step-by-step guidance.
When you run W8 on top of something else, it disappears. Try finding a recovery disk and start with a Boot Repair Disk.
The installation window will display a message asking for permission, and ignoring it may prevent the software from setting up correctly.
I'll remain here indefinitely until a power or hardware issue occurs.
