On a Y410P Lenovo IdeaPad the customer got the following message trying to install windows 10 after a bios upgrade: Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems Windows can only be installed to GPT disks. ComputerHelpSOS could install a Windows 10 version using the legacy setting in the bios and using an early Windows 10 version.
