Switching from Legacy BIOS to UEFI

Jump to solution

Hello,

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.

When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up fine Windows 8 just fine. What I like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under the UEFI.

Running BIOS version A10.

Any help would be greatly appreciated! I've found a couple articles but I just want to make sure I'm headed in the right direction and if maybe there is a safer and easier way to get this done...

For anyone who is in my particular situation, I found the solution here: http://www.eightforums.com/tutorials/2328-uefi-unified-extensible-firmware-interface-install-windows-8-a.html

You'll need to enter your BIOS and re-enable secure boot. Once enabled, save and exit, hold F2 and UEFI boot options will appear. If you're using a CD/DVD to boot, select "UEFI: TSSTcorp". Hit enter and Windows will boot to CD/DVD.
