I'm new to Legacy and UEFI terminology, so please go easy...
Dell XPS15 with Samsung 840 250GB SSD (replaced original mechanical drive) + 32GB mSATA drive (still present). It was set up to boot from UEFI when the Dell technician installed the OS on the new Samsung drive. Am I correct in saying the mSATA drive is not being used at present as the new Samsung SSD replaced the original mechanical drive?
Problem: Today I've wiped the 250GB SSD and installed W8.1. Problem is I installed it in Legacy mode as I couldn't get the W8.1 DVD to boot in UEFI mode. I think this was a mistake. I thought I could switch it back later from legacy to UEFI. The laptop will not boot now in UEFI.
Is there any way to switch back to UEFI for faster booting? I have a macrium reflect image of the new install, or would this just use Legacy again?
Is a complete reinstall needed, this time in UEFI mode and via USB?
Thanks
Ian
