I need to know if you can help me since with my little knowledge, my papers were burned, the bios does not recognize the internal disk, but windows when I want to install any version, yes? Look online but it is all the other way around, the bios recognizes the disk but not windows? Another test I did was to try to install windows to boot from an external one, I did it in GPT and in UEFI and it worked that way? I tried to delete the CMOS but only modify the date, but not another thing, the weird thing is also that it creates the bootloader, for example windows bootloader, but when the disk does not recognize the bios does nothing, that I modified the clover ?, so much damage could it have done ?, I know there are some live cd for Check the bios, but I can't find them, others talk about reprogramming the eepromm but I don't have that tool to do it, I don't know what to do because the machine is unusable, you have another idea? I have no idea how to do an opencore or nothing like that Do you know another tool? Thank you very much in advance if you can give me a hand, greetings and hugs
