Re: Sony VAIO SVS151190X w/ SSD RAID 0 and Windows 8
Almost everything you want to do is very feasible but daunting if you are not an experienced linux user. I presume your 'second drive' is not a raid? In that case your best bet is to install to the non-raid with that drive set as boot. That way you will write the grub bootloader to that drive and leave the Win8 bootloader alone. You will have to develop some familiarity with your 'BIOS' and how to change the boot order in it.
This done successfully will leave you with a system That is unbootable with Windows unless you restore the original 'BIOS. boot order, but you will at least be still be able to boot windows by doing that.
I will only outline the steps you have to go through to make it a dual boot system. In my experience, when you install an Ubuntu system to a non Raid drive, that installed system does not automatically install the linux software you need to access the RAID drive. While booted into your new Ubuntu install on the non RAID drive you need to install dmraid to it and do an update-grub to find Win8 on the RAID drive. You will then be able to reboot into a dual boot system and have access to both Ubuntu and Win8. If you must have something like the more colorful Win8 boot menu your easiest route will be to customize the grub boot menu.
Although what I have told you is completely inadequate it is the best I can do right now since I must leave the house for my usual Sunday morning engagement. Will look in on you later to see what is happening but a few others can jump in to answer some of your questions, Good luck.
