|The OP didn't clearly state which OS he's running. He has Linux x86_64 listed for his specs but mentions Windows in his post. If he has WinXP, what's happening makes perfect sense if he has a SATA HDD.|
"when bios is set to Raid system says No hard disk found"
The RAID/SATA drivers are required for XP to recognize a SATA HDD, without them "no hard disk detected" is the outcome.
