Unable to install OS
Is the hard disk drive properly installed?
→
Make sure that the hard disk drive is installed securely and that cables are properly connected.
Is the disk format correct?
→
Follow the table below to create a partition depending on the boot mode.
Boot mode
Disk format
UEFI Mode
GUID partition table (GPT)
Legacy Mode
Master boot record (MBR)
For example, the following message appears if an MBR disk is specified as the system drive of Windows

To change the disk format, clear the partition configuration and create a new partition. All of the data on
the hard disk drive will be deleted. Back up necessary data before creating the partition configuration.
