Yes, I have literally tired everything. The Windows loader created by DAZ version 2.2.2 which always worked before on my older computer - DELL XPS Studio 8100, won't work anymore on my new UEFI piece of crap motherboard which is MSI Z97-S02. Unsupported Partition Table Unsupported Partition Table Unsupported Partition Table All the mother f****** time. I have tried to convert my both harddrives to mbr before installation but it still does not work. It always turn out to be GPT afterwards. I have got this message too before installation (((Windwos 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.))) Well, I clean everything through diskpart so I can go on with the installation, but I can't activate my Windows 7 Ultimate x64. RemoveWAT is s**t. Because it does not say that my Windows is activated, it just says 'WORKGROUP', which I clearly do not like since I am so original. I wonder if there is anyway I could solve this? Does anyone have a key for Ultimate which actually works? Does KMS works for 7? Or MTK? I have heard something about WINDslic or so? Or should I go to the thread > 'Activate Windows 7 on PCs with UEFI'? Help out someone, thanks!
