Backup mo muma ts lahat ng important files before proceeding. Prepare ka usb atleast 8gb. Download tayo ng iso ng windows, kung anong version gusto mo. Gawin natin flashable drive usb using an app. After nun restart and access bios, set mo yung usb mo na 1st bootable device. Then save bios and restart. Kung gusto mo mas malinaw and much explained na process, whisper me.
