My Dell Vostro 2520 64-bit laptop. Shows the following error on power on.
Internal hard disk drive not found
To resolve this issue, try reseat the drive
No bootable devices -- strike F1 to retry boot, F2 enter setup menu, F5 enter PSA
I ran the F5 Dell internal diagnostic tool. It shows all the rest of the peripherals working correctly except no hard drive status.
The last thing I did with the laptop was to install Virtual Box and install Windows 7 32-bit OS in the virtual guest machine. The next day I got the hard disk not found error. So tried to repair any possible corrupt OS to boot from USB drive but on reboot I get a similar "No bootable devices" error.
The legacy option is enabled and secure boot is disabled in the BIOS.
To fix a possible configuration issue tried to boot from USB drive to repair os but again it shows no bootable device found error. Tried with different usb drives hp and sandisk, USB drives are recognized and shown in the bios but while booting it show no bootable devices
What could be the possible cause and fix for the problem.
