All of this is good advice, but ONLY IF the MoBo has been configured to boot |
43 |
in CMS/Legacy_BIOS mode. Otherwise, UEFI will bail out at boot time because |
44 |
it does neither read, nor use the MBR bootloader. |
45 |
|
46 |
Depending on the boot options provided by the motherboard, the hard drive can |
47 |
be configured to boot in legacy-BIOS using an MBR, in UEFI mode using an ESP |
48 |
partition, or both depending on the BIOS selection at boot time. |
