Setting up RAID 0 on new SSDs

Hi there,
I'm new to forums so please bare with me,

I've recently bought 2 250Gb Samsung EVO SSDs and want to RAID 0 them, then transfer my OS (and a few games) to them and keep my current 1Tb Seagate Barracuda HDD for the storage. I have fit them into my computer fine and (still running in IDE mode and booting from the HDD) they show in the Samsung software so I know the computer can see them.

I then put my BIOS into RAID mode and set up the raid 0 for the SSDs no problem, still booting from the HDD. I was told from a friend this would be fine as would be able to use the Samsung software to then transfer everything I wanted no problem then set to boot from the SSD.

However, this is where the problem started, windows started to load but went straight to the system restore and trouble shoot menu. I reset and let it try and sort itself out a few times before thinking something wasn't right. I was then worried about the integrity of my OS and all files on my HDD so unplugged the SSDs, deleted the RAID setup and changed it back to IDE in the BIOS. All worked perfectly so the HDD is fine.

Clearly I am doing something fundamentally wrong and haven't set something to the right option or what my friend told me is wrong and I may possibly need to do a clean install (which would be a real pain in the neck).

Any help on this would be really appreciated, I am new to RAID and SSDs so I am hoping there is something simple I am not doing to sort this problem out. System specs are below.

Thanks in advance for any help.

Sounds like you did everything right. When you had the SSDs installed as regular drives did you go into disk management and format both drives just to make sure both SSD drives are working properly? If both drives are okay and you then went into the bios to set them up as one raid drive, Windows should have booted properly from your HHD without any problem.

The EVO drives are cheaper for a reason, I am starting to think that the Samsung 840 EVO SSDs should not be used in Raid mode.
