    Hi Sherviniii, sounds like you're dealing with a corrupted bootloader—especially if Windows Boot Manager isn’t showing after install attempts.

    Here are a few options that might get things back on track:

    🔧 Option 1: Reinitialize the boot drive from another PC

    • Remove the SSD and connect it via USB to another computer
    • Open Windows Disk Management
    • Delete all partitions and format the drive as GPT
    • Reinsert the SSD and reinstall Windows using a clean UEFI boot method

    🖥️ Option 2: Use Diskpart in Safe Mode or Recovery Command Prompt If you can access the recovery screen or command prompt:

    • Type diskpart
    • Type list disk
    • Type select disk [your disk number]
    • Type clean
    • Type convert gpt
    • Type exit

    Then restart and reinstall Windows with Secure Boot disabled temporarily.

    🏥 Option 3: Acer Service Center Reset If you'd rather go official, Acer techs can restore factory defaults and reflash the EFI and recovery partitions for you.

    💡 Bonus Tip: Use Rufus to create a UEFI-GPT bootable USB installer. Temporarily disable Secure Boot for a smoother install if needed.

    Let us know how it goes, or if you hit any specific error messages—we’re here to help!

    options 1 and 2 is not working. Is there a tool that I can reflash them by myself?
