Why WSS WSSE unable boot from HW RAID which create from BIOS?
According the user guide doesn't mention to HW or BIOS RAID, and the WSSE OS recovery made from Microsoft default as AHCI mode only, if you went to use RAID mode have to reinstall WSSE OS in RAID mode, but it is not embedded WSSE anymore and you have to purchase standard/retail Windows license to install, also if motherboard changed from difference chipset and old HW/BIOS made RAID couldn't recognized from new motherboard, we afraid it is not a way, thus recommend keep BIOS stay at AHCI mode for Windows RAID from disk manager or Storage spaces would be better.
