I bought this unit used. I have tried to rebuild by holding down the shift key - reboot and select troubleshooting menu. Then rebuild by selecting wipe all user information and starting fresh. It gets maybe 49% and shows error encountered and no changes were made. It had a BIOS supervisor password but by unsoldering the RTC battery and disconnecting the internal battery, I was able to clear the password. Now, I have gone into the boot menu and set it to boot from ANY USB device and the optical drive. I have inserted Windows 10 USB drives and inserted bootable CD into the optical drive. The laptop refuses to boot to anything even though they are set to top priority in the BIOS boot order list but just goes back to the Windows login screen where the old user password is asked for.
I am a computer tech and have rebuilt hundreds of desktops and laptops. I would LIKE to just refresh what is on this one already and remove all previous owner information and files. But if this does not work, I would like to install a fresh SSD and load a fresh copy of W10. But nothing I have attempted has worked. Installing a new formatted SSD I get the message no bootable devices. I have inserted bootable UDB devices as well as W10 DVD. NOTHING has worked, all media is ignored. And there is no Legacy support option that would really allow me to boot from other connected devices.
HELP!!!! Please!!!
