    These are fairly common issues when switching from ACER WinHome version. If you can get online with wired ethernet to the router, download, install & run iobit's DriverBooster freeware to see if it will pick up any wifi & touchpad drivers that are better suited the the WinPro environment.

    Stay in UEFI mode with GPT disk0. Enable F12 boot option in BIOS Main tab. Then insert USB WinPro installation stick. Turn machine on and press F12 to bring up menu to boot from the WinPro installation USB  Jack E/NJ

    Hi jack I think I know what's the problem my windows bootable device (Windows 10 Pro )its in a format of MBR. Maybe I need to change this to GPT.

    How did you prepare the WinPro installation device? If a USB stick, use Rufus to prepare the WinPro installation iso file also for UEFI bootstrap laptop. Jack E/NJ

    partition system GPT and target system UEFI non-cms (not uefi-csm which is basically legacy emulation)

    Your HDD or SSD is not detected. Please F2 into the BIOS menu and take a phone photo of the BIOS INFORMATION tab. Jack E/NJ

    This BIOS version should not be in optane SATA mode. What problem were you trying to solve by installing BIOS v1.21? Jack E/NJ

    The legacy BIOS overlay option is being phased out on most new laptops. Does your laptop still boot WinHome right now without changing anything in the BIOS? Jack E/NJ

    Go to search in the Windows start menu. Enter optane. An Intel optane memory application should appear near the top of the menu. Depending on which Intel optane app you have installed, follow directions in this link to disable optane memory from your SSD. https://www.intel.com/content/www/us/en/support/articles/000024626/memory-and-storage.html

    Go back to the BIOS menu Advanced tab. Is there an option to change SATA mode to AHCI? If not, press Ctrl+S to see if a hidden option appears. Also check Main tab for SATA mode option. Jack E/NJ
