    Boot device unavailable


    But I can browse it in cmd prompt, made usb drive, ran boot rev /rebuildbcd it see’s windows and I add it, reboot..... device not available and usb won’t boot cause it’s bcd got changed.... I just want my install back, a different drive failed and caused the issue for some reason.... fixboot gives access denied as well.. part of the issue is I do not know which partition should be boot.. I have a 100mb system restore, my main partition (500gb) and a 569mb hidden partition

    Anyone have a clue?

    :)

    Wireless mouse "driver is unavailable" issues

    Hi,

    The error Driver is unavailable means that there is no available driver installed for your mouse that’s why it is not working. We suggest that you check the mouse driver from the device manager. Follow the steps below:

    • Open Device Manager.
    • Look for Mice and other pointing devices and click it to expand.
    • Check if there is a driver for the wireless mouse.

    If there is none, we suggest that you visit the manufacturer’s website of the mouse and download then install the latest mouse driver compatible to Windows 10.

    Get back to us if you need further assistance.
