So, what is that basically ? When i boot from my usb stick, i have the option to install in UEFI mode and in normal mode.

I know in UEFI mode it makes 4 partitions, and in normal mode just 2 partitions.

So basically if i install in UEFI mode i will have better windows 8 implementation and it will boot and post and run faster ?

What are the advantages for installing in UEFI mode vs normal mode ?

And why in UEFI mode the OS creates 3 additional partitions, instead of only one ?

Ok, didn't understant how helps with my problem.
I just wanted to ask, if is correct when i put my usb stick into the PC and boot from the line that starts with UEFI: (device name), that way i'm installing windows 8 in UEFI mode ?

Then, i need to make some boot setting into my UEFI BIOS, or just leave it at default, booting from the hard drive.

It will work in my SSD's ? The OS installed in UEFI mode will make the drives in GPT and not NTFS ? i dont understand this.

How to install Windows 64 bit on a uEFI/BIOS firmware:

UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Help Forums
or

Then, i need to make some boot setting into my UEFI BIOS, or just leave it at default, booting from the hard drive.

Set to UEFI defaults.

It will work in my SSD's ? The OS installed in UEFI mode will make the drives in GPT and not NTFS ? i dont understand this.

For UEFI.

HDD is in GPT mode, C: is formatted to NTFS.

For Legacy.

HDD is in MBR mode, C: is formatted to NTFS.

So in UEFI mode the C is always NTFS (as the legacy mode) ?

I have two 120gb ssd's from intel. I have both cleaned and no partitions made on them. Basically i boot with UEFI mode, then i apply for the installation to install on first partition (it will make 4 partitions), then i click new and apply for the second drive i have, and that second drive will be formated as GPT, and not as the usual NTFS ?

Hello Calin,

The drive will still be formatted as NTFS whether it's converted as a MBR or GPT. It's just that UEFI requires the drive to be GPT instead of MBR.

You would only install Windows 8 with UEFI on the first unallocated SSD as outlined in the tutorial above. It will convert this SSD to GPT instead of the usual MBR for legacy, and create the 4 partitions required for UEFI.

Since the second SSD is just your data drive, you don't have to do anything special with it. You can format it as MBR as usual if you like.

Hope this helps, :)
Shawn

Now i understand. When windows finishes the install i need to go to disk management and then convert the second SSD into the GPT format as well.

Basically the first SSD where i need to install the Windows in UEFI mode it creates it automatically in GPT, i don't need to prepare something..

Not quite there.

You don't have to do anything to the second SSD since it's not the drive Windows 8 with UEFI is being installed to. The second drive can remain MBR. :)
