Not posted from my own computer.
My writing computer is a Toshiba laptop, which has developed a boot error. All I can get is a black screen and a white arrow. Regular backups mean all is not lost, but I need to resolve issues so that I can get back to work.
My understanding is that this is likely to be a BIOS error. I have tried several methods for clearing it suggested on the Internet, but if any of you are computer gurus who have an idea how I can proceed, I would be happy for the advice.
