How to install windows on the SSD (Y580)

Question

I have bought an Y580 recently wIth a 64GB SSD and 1TB HDD. I asked the salesperson upfront if the OS would be on the SSD. He said yes. Turns out that it is not. When i returned to them they told me it's a hybrid drive solution. And they have no idea how to install Windows on the SSD.
I did some research and found out that Lenovo uses *Rapiddrive* to speed up programs. Hence why i can't see the SSD in WIndows as it is merged with the 1TB HDD.  In Disk management 2 disks show , 0 and 1 , but Windows asks to give disk 1 a MBR or GPT (this is apparantly due to the rapiddrive methode).
My questions:
* Is it possible to install Windows on the SSD and if so how can that be done without loosing the backup on the hidden partition of the 1TB disk? (so that OKR still works)
* What are the benefits of Rapiddrive over using the SSD as bootdisk?

Answer 1

Since it is a hybrid drive, it works a little bit differently; Lenovo's "Rapiddrive" is also different from other hybrids, and in the sake of making it "user friendly" and seen as a single disc they have probably nerfed some configurability for the intermediate/advanced users. However, Windows should already be installed on the SSD portion of the drive, this should be done automatically according to this press release:

"In the factory we will preload not just Windows 7 on the SSD, but also our Lenovo applications like OneKey™ Theater or OneKey™ Rescue System. The applications, operating system, drivers and other files are all fully-optimized for Enhanced Experience to make them load much faster. This, combined with their installation on the SSD will make the boot time to Windows desktop even faster. Some portion of the SSD will also be reserved as the Windows Paging File — this is used by Windows as 'virtual memory' additional to the normal RAM installed inside the computer. With the SSD acting as the Paging File, general Windows 7 performance will also benefit, especially when multitasking several applications.          
The remaining space, which will typically be around 15GB on a 32GB SSD, will be empty, ready for the user to install their favorite applications and files."
I have some of the fastest SSD's around installed on my desktops (SATA III), and while they are blazing fast, keep in mind the whole boot sequence still isn't going to be instantaneous even with an SSD (the biggest differennce you will notice is by the time Windows is loaded, it's fully loaded to the RAM, whereas a normal HDD you may see the desktop but your PC will still be cranking away with startup processes). If your startup is taking 30 seconds or less, maybe even a little longer, it's probably accessing the SSD just fine; if it's taking closer to 60 seconds, then yeah it may need to be reinstalled/reconfigured.
As for reinstalling, sorry I won't really be able to help, hopefully someone else can come along; I personally have never used OKR anyways, and aside from doing a ghost backup I wouldn't say for sure that OKR would be salvageable with a fresh install. And because the Rapiddrive is its own technology, half SATA half PCI-E, I also couldn't tell you if it's even possible to fully seperate the two and keep them as distinct drives.
