After installing new hard drive in Inspiron 14R N4010, error "operating system not found!"

This question is not answered

I have Inspiron 14R N4010. Its 2 years old. Its Toshiba hard drive(320 Gb) crashed 8 months before so I bought new WD hard drive(500 Gb), which also crashed again 2 weeks before(OS drive had bad sectors apperently) . Hence i got it replaced by WD for a new 500Gb hard drive.

Now, when I am trying to install OS in my new hard drive, i am getting following error:

Intel UNDI, PXE - 2.0 (build 083)

Copyright (C) 1997-2000 Intel Corporation

For Atheros PCIE Ethernet Controller v2.0.2.3(06/18/10)

Check cable connection!

PXE-M0F : Exiting Intel PXE ROM.

Operating System not found.

after learning about possible mistakes by reading some forums

1) I checked that hard drive is installed properly, all connections are good.

2) DVD I'm using to install Window 7 is bootable one & i have used it before

3) BIOS settings are checked to boot fromCD/DVD drive. (It is not booting from network adapter which supposed to be reason for ethernet error as per many other forums)

4) I tried draining current by pressing power button for 20 sec to reset settings.(I read in some forum) but even that didn't worked.

BIOS is detecting hard that is also not issue.

Could new hard drive be damaged? should i get this new one also replaced again? I need some way to confirm this before me sending it back to WD.

In one microsoft forum, I read for same problem

"update the basic input/output system (BIOS) to the latest version by contacting the motherboard or computer manufacturer and check if it works.
Important: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

ref :

Since modifying BIOS setting involves risk, i would wait to do that before any other suggestion/solution.

Reply would be appreciated!

  • The CD/DVD drive needs to be selected at boot (F12 at powerup, or before the hard drive in the boot list in BIOS setup).
