The topic should read removing win 8

Already disabled the secure boot, enabled the kegacy boot and began the install. Deleted the partitions and combined unallocated space and formatted to one partition. Now it tells me that Windows cannot be installed on that partition because the hardware may not support booting from that device, and to make sure that the controller or this device is enabled. Anyone know how to enter the bios and what controller needs t be enabled?

This is an HP all-in-one PC.

Thanx much!
