Make a Win 10 or 11 installation USB sttick with it, boot from the stick and choose in one of the first pages below in the left corner the Reparation option Therein you can check the bootparameters ( Start repair ) and you could check in a windows terminal with diiskpart if the old disk is seen at all. read in the internet abou´t diskpart how to do this. daddle
