I just bought a Dell 14z 5423, which uses UEFI/GPT and Intel Smart Response on the Windows 8.
I have been researching and studying how to use it as Dual boot.
Thanks to this forum I was able to install ubuntu 13.04 alongside with windows 8, disabling IRST and changing Sata Mode to AHCI.
Although I haven't was able to enable the ISRT yet, I, letting Sata Mode to ACHI, was able to boot both windows 8 and ubuntu.
Today I started it and ubuntu does not boot anymore. Nothing has changed. I could say that i installed some updates, by I had tested and it was ok.
Why it's been so troubly to have ubuntu + windows 8?
What do I have to do to have my ubuntu booting again?
What do I have to do to install ubuntu drivers for RAID (Intel Smart Response), and then how shall I use the accelerate mode in both discs?
I really appreciate your help.
