Device can't access BIOS or start from DVD/USB drive.
You're looking to reinstall Windows 8.1 on your laptop. It seems the USB drive didn't load properly, and you're stuck in BIOS without access. You've tried disabling fastboot and using a Windows 7 DVD, but neither worked. Consider checking if the USB is properly seated or try a different USB port. If that fails, you might need to use a live USB with a recovery tool or contact Microsoft support for further assistance.
Remove CMOS, then follow your guide. Also check the BIOS battery and regular battery, restart it normally. This usually resolves the issue.
You might try alternative methods without removing the CMOS battery, such as using a jumper wire to reset certain functions or consulting the user manual for safe troubleshooting steps.
You might quickly update the BIOS (good luck and avoid mistakes)
