I installed a new cooling fan in my HP pavilion dv7-6135 laptop. afterwards, upon startup, I get a black screen with the blinking cursor in upper left corner telling me to install an operating system. I inserted the win 7 64 bit disc and can boot from that and eventually get the comp running.

how do I fix this so the comp boots normally? its almost like the bios is missing? I also ran the diagnostic tests that the comp told me to run...no memory problems and hard drive passed tests also.

If I may chime in folks  :)

 

What is the boot order set as in the BIOS.

 

Boot from the Windows disk then grab a screenshot of Disk Manager for us and attach it to your next reply;

 

1. Click on the Start button and then choose Control Panel.

2. Click on the System and Security link.
Note: If you're viewing the Large icons or Small iconsview of Control Panel, you won't see this link so just click on the Administrative Tools icon and skip to Step 4.
3. In the System and Security window, click on the Administrative Tools heading located near the bottom of the window.
4. In the Administrative Tools window, double-click on the Computer Management icon.
5. When Computer Management opens, click on Disk Management on the left side of the window, located under Storage.
After a brief loading period, Disk Management should now appear on the right side of the Computer Management window.
Note: If you don't see Disk Management listed, you may need to click on the |> icon to the left of the Storage icon.
 
To capture and post a screenshot;
 
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.
 
Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

The contents of the HDD are as they should be which hopefully is a positive sign.

 

What is the boot order set as in the BIOS.

That is also as it should be so can I ask if you can boot into Windows and then remove the disk from the optical drive, if the computer stays within Windows follow the steps in my canned text below;

 

To see if this is a Windows issue download then run the All in One Repair from here, disregard the malware guidance but follow the other steps to the letter and in particular ensuring that you first create a new restore point and perform a proper Windows clean boot before running the repair, details for the clean boot here.

 

 

Nothing to suggest that the HDD has issues at the moment btw but it would be prudent to back up any important data if you have not already done so.

I ran the tweaking program twice as recommended. still am not able to boot from the HDD.

 

I still get the dark screen with the message - boot device not found please install an operating system on your hard disk (3F0)

Generally it is under Advanced option in BIOS but i am not sure where it was in your pc bios,

If the option is selected for RAID/AHCI or Hard disk is off state similar to below the hard disk will not boot,
