has anybody successfully converted existing win8 UEFI bootable (GPT SSD) installation from SATA AHCI mode to RAID mode?
my win8 os has been installed in UEFI+GPT mode on SSD AHCI and works great ... it's just I'd like to make it bootable in RAID controller mode as well ... the IRST driver is installed in OS, registry key for iastorv is set correctly.
I am having a hard time just making my existing win8 boot off the intel SATAIII/6G controller in RAID mode (works only in AHCI) when running UEFI+GPT ... and yes, I made sure that iastorv key in registry is set to Start(0) ... that was usually enough in "normal" BIOS/Legacy boot mode to make the win7 OS boot successfully in RAID controller mode ... not so much for my win8 UEFI LOL! always BSOD ... no bootable drive present....
just to clear things up, I am currently running OS on a single SSD, but I want to make it boot from controller in RAID mode so I can back it up and then restore on RAID0 volume ... so far I fail on prepping the OS and I really wanted to simply convert it instead of a fresh UEFI install on RAID volume ...
also to complicate things a bit more, it seems that Intel RAID controller doesn't even get activated with CSM Disabled (no drives detected in BIOS) while it detects all drives normally with CSM set to auto or enabled. Can live with that, I guess for the price of slower boot up in RAID mode ... just need to know what I'm missing to finish off the conversion from AHCI to RAID....
EDIT:
background info:
a) board: ASUS MVE with 1707 BIOS; RAID OROM firmware on board 11.0; IME fw 8.0
b) IRST driver installed currently 11.7 (from Intel Download Center)
wondering if perhaps I should try earlier IRST driver 11.5, officially supported by ASUS...
