    Hello,
    CSM and boot options got reset (i think these are the only ones i changed to begin with.)
    thus as a result, the booting process tried to launch from HDD causing inability to boot successfully.
    i have my win10 on fairly recent SSD, aftering changing boot settings to how they should be, system started as usual. no new errors in event viewer, no new DMP logs.

    what do you think? what could cause this? error in motherboard, SSD, corrupted bios files?
