Properly disabling Intel SRT
Solution 1:
In your BIOS you should be able to disable the intel SRT feature. Once you do this, use GParted, to format this drive ( I also had to create a partition table on the drive.) Go ahead and install windows and linux. grub did the rest for me automatically. But first do check that your BIOS can also find the SSD.
If your windows is still not installed then just dont install the driver for SRT. Otherwise I guess you'd have to disable it first. I deleted windows soon after buying the PC so I didn't have to do this.
In any, case I am currently back to the way the laptop was shipped (almost) and looking for ways of trying to cache with ubuntu. If its even possible!
PS: I was first just trying to install with dual boot. I saw that for the ubuntu installer to find the HDD I had to type in dmraid -E -r /dev/sdX
with X being the drive. After I did this and rebooted I got a sscreen printing the HDD + SSD RAID(fakeraid) setup and asked to to press Ctrl + i to configure. I went here and this is where I was able to fully disable the SSD caching and use the drive for installing ubuntu.
