    Upgrade to 20H2 failed


    The laptop was offered the feature upgrade to Win 10 20H2. It is still running 1903. It had failed 1909, 2004 with this error 0x80004005 - 0x1000A,The installation failed in the DOWNLEVEL phase with an error during PREPARE_FIRST_BOOT operation.


    Since Microsoft does not like this laptop anymore I had done a chkdsk, a SFC / scannow and a disk error check from the properties tab. All errors fixed.

    I stopped MS secutity, firewall and the Avast security for the upgrade.

    Downloading and installing took some time and it looked as if the laptop was going through the motions. At the end it had just reverted to 1903 again.


    What else can I do short of a complete reset?

    :)

    What do you mean "no good"? At which step did it fail?

    20H2 and Firewire/Audio issues

    I have a MOTU Ultralike MK3 which I have connected through Firewire on my desktop.

    My specs:

    • ASRock B450M-HDV R4.0 Motherboard
    • AMD 3800X
    • 32 Gb DDR4
    • Vantec PCIe Firewire interface with Ti chipset

    Before my upgrade to 20H2 - my playback was quite stable but since this upgrade, I'm getting a bunch of weird playback glitches. That is not even under load. I just play a file in JRMC with the ASIO interface and I get multiple drop-outs glitches. The playback
    definitely stops for 1 sec or so, there is no level showing up anymore during that second on my audio interface.

    I changed two times already the firewire cable, and the firewire card as well.

    My bios doesn't have a lot of options and I have the legacy 1394 driver installed which used to work quite nicely.

    Any suggestions?
