I have a Lenovo U310 ideapad which I need to install Windows 8 on.  I boot to USB containing the OS, and choose custom install.  The hard drive on the laptop is not seen.

I have downloaded and extracted both the Raid and the chipset drivers from lenovo, added them to a second USB drive and tried to load the driver.  I receive the message that 'no signed device drivers were found".

I went back and looked at the extracted folder and within the \2. intel rapid storage technology driver folder is a Setup.exe and handfull of .iss, .inx, .hdr, and .dll files.

The laptop has a rapid storage flash drive for boot, along with the HDD, thus the RAID driver.  

Do I need to make a change in the BIOS in storage; change it from RAID to AHCI
Also, under Intel Rapid Start Technology there are three options; iRST is Enabled, Entry on S3 is Enabled, and iRST Partition Status is Enabled.  Disable these?

I am not exactly certain, but that machine would only have one drive, so it should be set to AHCI and not RAID.

I think you can ignore the Intel Rapid Start variables. They should not prevent you from seeing the hard drive.

In the BIOS, the settings available for :
Sata Controller working mode
are:
Compatible
AHCI
RAID

It is currently set to RAID because it is using Intel Rapid Start.
I am thinking that the only way to get the drive recognized is to take it out of RAID mode, but am looking for input as to whether there will be any issues.

Compatible: SATA controller operates in IDE mode
AHCI mode: SATA controller operates in AHCI mode.

@AE_JB - I assume that taking the drive out of RAID mode worked for you.
