I am setting up a clean install using Win7 SP1 and I am confused about this setting in the bios of the motherboard HP Prodesk 600 G2 SFF for enabling UEFI. I have the bios option of “All UEFI” or “All UEFI except Video”. What issues do these settings present and which is the best setting. I would like the know the difference in behaviour of these two settings. Does windows 7 require Legacy video information regardless. My preference is UEFI and AHCI for drives. I have not yet purchased the new graphics card and the wide screen Samsung monitors were purchased around 2010. Any ideas? Thank you in advance.
