Hi I have a Toshiba portege z30a and i tried to reset it but once it reset rather than reinstalling windows it says no operating system found and the bios has a password which I dont know. So I wanted to reset it by jumping the CMOS jumper or removing the CMOS battery but I can't find any of that. Can someone please help me find it because I can't use this computer unless I reset Bios and install Windows 10.
