Hello, I have a Sony Vaio SVE14117FLB laptop, it does not have UEFI mode, only legacy mode (or at least in my bios, the UEFI option does not appear) I have tried to install the high Sierra version but it simply does not start.
i52450M processor
Ram 8GB DDR3 1600mhz
AMD Radeon 7500/7600 Series graphics (does not allow Intel HD3000 to be enabled)
SSD Kingston 256GB AHCI mode
realtek PCIe gbE Family Controller ethernet adapter
