I have to do a clean install because of a died SSD. It seems that it's impossible to install in UEFI mode with raid 0, using a modded bios with updated Intel OROM.
My raid setup does not appear in boot priority; it's seen by Win, but I can't install because it's not possible to boot from that drive.
Did someone exerienced this on a Z77?

Thanks. Actually I'm waiting for RMA of my SSD, so I'm using a couple of old 80Gb HDDs (so I'll be able to ghost to my SSDs when they'll return).
I tried with Windows 8/8.1; I set up my raid 0 array in UEFI, it is shown as "Normal". But it doesn't show up in boot priority; when I try to install, I can see it (with 8 I need to load the drivers, with 8.1 are included), but I can't format it in the 4 partitions and I can't install SO because "the drive is not bootable". I don't think I miss something (I did the same on first install), how to set it bootable? Could it be because of an old HDD?
Installing in legacy mode works.

Check out this guide: Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs

You can skip to the part of the second post labeled: Configure drive using an UEFI motherboard and GPT format

That should get you taken care of.

What does "in UEFI" mean? Does it mean, that you used the "Intel Rapid Storage" tab (= SataDriver) within the "Enhanced BIOS Options" section?
If you want to create a bootable RAID array, you should unplug all other HDDs/SSDs except the designed RAID members, before you create the RAID array.

After having disabled CSM in the BIOS, but before having installed the OS onto it in UEFI mode (using GPT instead of MBR), you will not see the RAID0 listed in the CSM disabled BIOS as bootable device.

Yup, the satadriver tab with just the 2 HHDs connected; I just set up raid, reboot, enter bios, my array is in the tab, but not under HHDs priority nor in boot priority. 13.1.etc OROM. If I disable CSM I don't use the satadriver.ffs, but OROM and OS will install, but not in UEFI mode

How do you try to install the OS in UEFI mode?
Is the bootable DVD/USB drive containing the OS image shown as UEFI drive within the "Boot" section of the BIOS?

Thanks, Rufus doesn't give me the option of install in GPT, but just MBR...

The easiest way is to format the stick by using diskpart and copy the files with xcopy:

open command line, then type "diskpart"
list disk
select disk x (x = usb stick)
clean
create partition primary
active
format quick fs=fat32
exit

then just use "xcopy X:\* Y:\ /s /e" (X = CD ROM with Windows or mounted image; Y = USB stick)

This is not true. Please look to the options on top of the Rufus GUI.
If Rufus doesn't give you the option for a GPT install, your OS image is not complete (missing the EFI part).

Yup, I don't have another EFI OS, I was using XP...
