Windows 7 installation Problem in Lenovo B570 Laptop

Hi, I have run into a problem have (Lenovo B570) DOS-BASED. When i tried to install Windows 7 it did not let me do this and crashes within installation.

I am describing in following steps how and what problem i faced during installation
1- I put Windows 7 CD and laptop successfully booted with Windows Setup.

2- While copying windows files to hard disk.
3- After step-2, rather moving on next setup screen, blue window appears have a long error description. The key point in Error message was something like this:
"An unexpected error occurred and setup needs to shutdown" then nothing happens...

2- I have tried with with the replace of ram , I cleaned the motherboard fan too but same result!!!
I am think it need BIOS setting required?

3- I have gone through on some article and someone mentioned there that, on lenovo machine SATA configuration must be set to IDE rather than ACHI(in BIOS)!!!
Can you suggest me how to do the right thing, what should i do?

Thank You.

Unplug all other HD's and peripherals,

Check for newer BIOS update.

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS, enable Legacy BIOS or Compatibility Support Module, set DVD drive first to boot, HD second. Then set SATA controller to AHCI to try that first. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10 to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.
