    Black Screen Before Startup - Help Reading Boot Trace File


    Hi all,
    This is my first post, not sure if I should have introduced myself first?

    I am experiencing a quite long black screen between the BIOS and the Windows Logo.
    Windows is installed on a Samsung SSD, while docs and stuff are on other internal HDDs, which are excluded from startup in BIOS. Once the Windows Logo comes up, everything is ready in seconds.

    I thought this could be due to my new video card (GTX 1050 Ti) so I updated the driver, but nothing changed.
    This also happens when rebooting, but anyways I also tried disabling hibernation and fastboot. No luck.
    I then found this post (Startup takes too long at Winlogon Init) so I ran a boot trace. PC restarted and got stuck on the usual black screen but for several minutes, so I eventually forced a restart by pressing the power button, usual black screen again, login, and then a popup saying the trace was being completed.

    Here is the trace file: Dropbox - boot_1.etl - Simplify your life

    I hope someone can help me figure out what is going on?

    Thanks in advance!
    Roberto

    Did you cloned the HDD into the SSD?
    Did you try to boot from the Win 10 drive and do a boot repair?

    Hi,
    I have updated my specs as requested :)

    I did a clean installation when I got the SSD.
    I did a SFC and DISM scan and fix before the boot trace but I haven't tried a boot repair. How is that done? Should I use the bootable USB ISO?

    Done, nothing wrong came up.

    *Edit: Why is "G:\WINDOWS" the Windows directory, instead of C:? Is that normal?

    Here is the log file:

    Hi @RMango and welcome to tenforums.

    please compress your boot trace before re-upload it again. I'll try to take a look.

    Did the other SSD and / or the HDD once had a OS on it?

    Please post a Disk Manager image (FULL window and expand the columns so we can read them)

    So, I also tried disconnecting the 3 data drives, only leaving the Samsung SSD and I got an A2 error code from the motherboard. Looks like it doesn't recognize the OS on the drive? If I press F11 and manually select the drive at boot though, it doesn't give me any black screen and Windows loads up immediately.

    The data drives have never had any OS installed on them. The Samsung SSD is the only one I have always used for the OS.

    Here is the Disk Manager screenshot:

    The boot trace doesn't show delay; the delay may occur during the bios phase.

    Ok, not sure if this is good or bad news. Any suggestions on what else to check?
