HP Recommended
Product: HP Z240 Tower Base Model Workstation
Operating System: Microsoft Windows 10 (64-bit)

Upgraded BIOS to version 1.92 via sp154352. Now I'm unable to boot into the BIOS menu. Tried F10 during power up. Get 1 beep at power up & black screen.Tried Ecs during power up. Same results as F10. Tried removing the CMOS battery, power up, power down, reinsert CMOS battery & power up again. PC boots up but BIOS version still at 1.92. Tried pressing the button on the CMOS jumper(?) with the PC unplugged & powering up again. Same results as removing CMOS battery. Ordered USB Recovery but I'm not able to boot from USB. Inserted the USB in machine & ran setup.exe. It reinstalled Windows 10 but nothing else (i.e. HP software) & did NOT reset the BIOS to factory default.

 

I can boot into Windows just fine but am not able to boot into BIOS & cannot go back to a previous version of BIOS.

Can someone help me either reset my BIOS back to default (preferred option) or uninstall sp154352 & revert back to previous BIOS?

 

Z240 Tower with Windows 10 installed.
