HI everyone. I have both bios and hard disk error.
"Boot Device not found
Please Install an operating system on your hard disk
Hard Disk (3F0) "
And want me to use diagnostics by pressing "F2" and when i do that this error pops up:
"The HP BIOS application Selected is corrupt or missing. Please install the application and try again.
BIOS Application Error (501)
And shows the "Enter" cmd but when i press it take me to above error massage.
Here is the list of the things I've done so far :
1. I tried to repair BIOS through recovery and all the USB bios recovery and others like "HOLDING POWER BUTTON and WIN+B or WIN+V combinations". When I tried the “POWER BUTTON and VOLUME UP” Combination I got the message SMC Command Failure.
2. I tried 4 in 1 USB key that HP support provided in support page but it didn´t work as well. I tried this with Hardware Diagnostics 4-in-1 USB Key v6.5.0.0 and with Hardware Diagnostics 4-in-1 USB Key v5.0.0.0.
3.I tried to use a bootable USB stick to start the Windows Setup and use the reparation Options and start a BIOS .exe to start up a BIOS Update that way but I ended with the message that the BIOS .exe is not compatible with the Windows-Version. I have tried different BIOS Version like v1.48, v1.33 and even v1.23.
Does someone know how I can get this Tablet working again and what steps are necessary for that?
Thanks in advance
