I tried to install win 10 on a Vostro 3491 with Ubuntu pre installed, I just boot up by usb and delete the partitions and re partition again for windows. It coppied the first files but after restarting it can't deteced hard drive anymore. In the boot meno in Boot Options it's not there and I can only add it by giving a file adress from Hard drive.
How can I add Hard drive again to boot menu and boot it up by windows on UEFI mode?
