I'm about to install Windows 7 64-bit to a Dell T7600, and for the first\ntime I am dealing with this new replacement for BIOS named UEFI. What a\nmess. It looks to me like this is a feature that doesn't quite work. The\nOS support for this feature is poor. The implementation in firmware looks\nimmature. In any case, the problem is that if you have a bootable USB\nflash on a USB 3.0 drive, it demands that you enable UEFI. I enable it,\nbut I cannot see the "UEFI compliant USB 3.0 Flash" from the T7600, so I\ncannot select it as a boot device. I'm booting a Passmark USB 3.0 disk\nwith their installed benchmark application on Linux.\n\nWhen I configure the T7600 for UEFI, and try to add a device, I get a\n"Missing File System" error. Does this feature require that I have some\nGPT formatted Windows system disk lying around for it to write its own data\nfiles on? I really don't understand the big picture here of what I need\nto have in my environment to use UEFI. Can someone point me to appropriate\ndocumentation? As usual, the Dell T7600 documentation is very poor and\ndoesn't begin to answer any real questions.\n\nAnd now the million-dollar question: should I even want to use UEFI in its\ncurrent state with Windows 7 64-bit? I gather it will cause more problems\nthan it will solve but would like to hear from others.
