Problem of Installing OS
[?] 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
GUID partition table (GPT)
Legacy BIOS
Master boot record (MBR)
For example, the following message appears if an MBR disk is specified as the system drive of
Windows on UEFI boot mode.
When the disk format is changed, the disk drive on which OS is installed is cleared and the new
partitions are created. Back up necessary data before changing the disk format.
[?] Unable to install Windows:
Have you checked precautions for installation?
