This is a bios file! Wew, I don't know how to deal with these yet.
Friend, for your SD card prob, also try:
1. uninstalling the SD card driver that's displaying an error at Device Manager (access D.M. thru Cortana/Win10 search bar) then rebooting
2. trying to find a way to format the SD card into NTFS instead of FAT32
method 1 worked for me once.. I'm currently trying to solve the same problem on my Hi10 Plus using method 2: I'll try inserting my SD card thru an SD card reader, format it to NTFS, I'll see if Windows reads it afterwards..
