All of this is good advice, but ONLY IF the MoBo has been configured to boot in CMS/Legacy_BIOS mode. Otherwise, UEFI will bail out at boot time because it does neither read, nor use the MBR bootloader. Depending on the boot options provided by the motherboard, the hard drive can be configured to boot in legacy-BIOS using an MBR, in UEFI mode using an ESP partition, or both depending on the BIOS selection at boot time. -- Regards, Mick
