Hello Eshwar,
1. Boot into the BIOS (for Dell press F2 while the Dell splash screen is showing, other computers may use a different button).
2. Go to Drives > SATA Operation. (will be different for a non-Dell)
3. Change from "RAID Autodetect / AHCI" to "RAID Autodetect / ATA" (or something similar)
4. Press escape, choose Save / Exit.

Play it safe, shut down your PC and disconnect all USB devices (except the keyboard/mouse) before trying to reinstall.

This can also sometimes be caused by bad RAM, you can use the memory test feature on the Windows 7 DVD.

This error might also occur if the hardware is not compatible, you may check if your computer meets the hardware requirements for Windows 7 from the two links below:

Thank you for your info. Let me tell you one thing, I'm getting this error "BOOTMGR is Missing" when I'm trying to install windows 7 using USB. In my laptop, I don't have CD drive. How can I install Windows 7 ..? Kindly, help me.

Thanks in Advance,
