I own a Dell Precision T3400 PC.
I attempted to clean install a linux distro, Ubuntu 14, from an USB bootable thumbdrive. No succes.
I wanted to go back to my Windows 7 installation.
After rebooting, I got the error
"No boot device available
strike F1 to retry boot, F2 for setup utility
Press F5 to run onboard diagnostics"
Looking for issues in the BIOS setup, I noticed that the option to change the Boot Sequence became inactive. Even if I reflash with any BIOS version, the boot sequence change option does not come back and the error “No boot… “ keeps coming.
The reseller change the mainboard. It worked perfectly, until I tried Ubuntu again, thinking there was something wrong with the mainboard.
Everything happened again, with the exactly identical results.
Have you got any ideas about this strange occurrence?
