UEFI Win7 x64 installation on my SSD

Have no idea but booting from the DVD gives you formatting options anyway.

You don't need GPT on a 60GB SSD. GPT is used for drives over the 2.2GB MBR limit.

Yes, UEFI must use GPT rather than MBR, so the partition type will always be GPT. The UEFI install will create 3 partitions on your SSD (The SSD has to be completly blank before install).

Partition 1 - ESP (100MB)
-The ESP contains the NTLDR, HAL, Boot.txt, and other files that are needed to boot the system. The UEFI drivers, as well as others needed to boot are located here.

Partition 2 - MSR (128MB)
-Microsoft Reserved Partition. This is space allocated on each disk drive for use by Windows.

Partition 3 - Operating System (The remainder of your SSD)
-Your data and everything else

Partition #2 will be hidden from the OS (you will not be able to see it in disk management under the windows environment). You can see this partition if you run the Diskpart utility after install.

These three partitions are necessary for an UEFI boot.

This is true

There currently is a potential problem (in some instances) with UEFI GPT partitions that are used to boot the OS. The problem you potentially have with a GPT partition is the inability to make a sector by sector image of the partition, for later resoration in the event of corruption to the OS. This problem is being worked on, and a solution sould be available down the road.

Copying the GPT partition means the GUIDs (Globally Unique Identifyers) for both the partitions and disk are no longer unique. Losing their unique attributes in the imaging process can, and does, potentially cause restoration issues. It is important that all three partitions involved in the UEFI boot be imaged at the same time for a restoration to be successful, and this does not necessarily guaranty a sucessful restoration. Snapping a good, usable image of the MSR (since it is hidden in the OS) makes this very difficult.

Are you saying that drives using a MBR can not be booted from when you are using an UEFI board or am I misunderstanding something?

No, I may not have been completely clear. I'll try to make it clearer.

Currently, a UEFI Motherboard can boot from both a MBR (drives under 2.2TB), or utilizing a "UEFI boot" depending on how the OS installation (and storage devices) was configured during install. Although not exactly correct, basically think of UEFI as an independant mini operating system.

When an OS installation is configured as I stated above with a GPT and ESP partition, this is considered a UEFI boot configuration. The MSR partition is specific to Windows.

Current UEFI motherboards can also boot from a software environment the UEFI creates that resembles a legacy BIOS, when the OS is configured utilizing a MBR partition.

The soon to be outdated Basic Input/Output System (BIOS) served as the OS-firmware interface for the original PC-XT and PC-AT computers. This interface has been expanded over the years as the "PC" market has grown, but has been in need of an update for a very long time. A BIOS is specific to the Intel x86 processor architecture, as it relies on a 16-bit "real mode" interface supported by x86 processors.

UEFI defines a similar OS-firmware interface, known as "boot services" and "runtime services", but is not specific to any processor architecture. It is still an interface that helps hand off control of the system from the pre-boot environment (i.e.: after the system is powered on, but before the operating system starts) to an operating system (Windows, Linux...etc.).

UEFI contains an architecture-independent mechanism for initializing add-in cards (Graphics, Sound, RAID...etc), which is why it stores its own drivers (independant of the OS) in the ESP partition. UEFI is also not restricted in operating only in 16bit mode as is required for a BIOS.
