Hi, I do not fully understand what settings you are changing and what you are trying to accomplish. Is it possible to share some screenshots with the exact steps you are going through?
I want to enable rapid boot for NUC 5i5RHY but I can't find Hibernation = Immediate in power menu. Do I have to set to RAID in order to see this option being enabled in bios?
I replied to your PM
Its best to ask, and answer, these types of questions in the public forums, NOT in PM, so everyone has the opportunity to benefit from the information you learn.
Let me rephrase my questions:
1. How do I enable intel rapid boot?
2. Do I have to install Win 7 in RAID mode instead of AHCI?
3. Why can't I find Hibernation set to Immediate in BIOS?
4. Will I need to reformat & perform a clean installation of Win 7 if I were to change to RAID mode?
Please provide me a full user guide to enable rapid boot and install the OS.
I think you mean Intel's Rapid Start tech? Contrary to what some sites are stating, neither Rapid Start nor Smart Connect seem to be supported on this Broadwell platform. Fast Boot seems to be your only option: Boot > Boot Configuration > UEFI Boot > Fast Boot.
Personally I wouldn't advise it, since it can cause other aggravations, and the NUC boots very fast from S4 as it is (~5 seconds with Win 8.1). Not really worth it IMHO.
... but I can't find Hibernation = Immediate in power menu. Do I have to set to RAID in order to see this option being enabled in bios?
Do you have latest <0247> BIOS installed ?
Yes I have the latest bios.
Just to confirm, NUC5i5RYH no longer support Intel Rapid Start.
To enable instant boot, I just need to go to normal windows hibernation? And to further speed up the boot, I just need to enable Fast Boot?
Its good to learn that I do not need to enable RAID, reinstall OS and to find out Intel Rapid Start no longer support in nuc broadwell.
Another question is, what is the feature or advantage then in Intel Rapid Storage Technology for Inte NUC broadwell?
If you have a SSD as the operating system drive, implementing Intel® Rapid Start Technology or Intel® Smart Response Technology does not make much sense as you already have the fast access of the SSD. These technologies take advantage of the SSD performance when the operating system is installed in a mechanical drive. Otherwise, Intel® Rapid Storage Technology only contributes to your system as an AHCI driver.
