Trying to install Win 7 on a Narrow Mini PC coming with Win 10 on board GPT disk, the system does not allow to convert to mbr:"Windows can not be installed on this disk. The selected disk contains an MBR partition table. Windows can only be installed on EFI systems on GPT disks."So i install Win 7 on gpt but when message * Windows is starting " stops i get the error: an unexpected error occured- error 0xc000098 or 0xc0000225-Winload.efi missing.I think Bios is restricted and limited to GPT. Bios options: Option 1. Windows Boot Manager Option 2. USB Option 3. Built-in EFI Shell The other option is "load optimized defaults ". Systeminfo:SSD 32 GB Bios AMI BT3016 Intel Atom x5-Z8300 CPU@1.44GHZ, 1441 MHZ, 4 log.ProcessorsRAM 4GB Can anyone confirm that the system has restrictions? Thank you.
