Windows 7: HP laptop won't boot up to window

HP laptop won't boot up to window

Hi! two days ago my HP laptop suddenly shut down by itself and now it doesn't boot up to window, just stay at black screen. I only got it for slightly over a year. I thought there could be something wrong with the hard drive so I went into BIOS to test it, but it passed both hard drive and memory test. I went online to do some research then tried any suggestion that I found in different forum, but still no help. When it just power up, I also tried F11 for system recovery option but nothing came up for me to do anything. Would someone please help! I'm moving out soon so I need my laptop!

I'm using HP Pavillon dm4-1165dx Entertainment NoteBook
Thanks in advance.

It sounds like your bootmgr went AWOL. You can use the bootable CD of Partition Wizard (last entry on this webpage) to see what is going on. See whether you have an active 100MB partition. If not, check whether any other partition is marked as active. And whilst you are at it, fix the MBR on the HDD.

See how far you get and report back.

Note: The active partition contains the bootmgr

Once you confirm Windows 7 or its boot partition are marked Active using PW CD, click on the Windows 7 HD to highlight it and select Rebuild MBR, Apply, reboot. This may preclude the need to run Repairs.

If not, boot into System Recovery Options to run Startup Repair repeatedly, report back results.

You can copy out your files using Windows 7 DVD or Repair CD this way: Copy & Paste - in Windows Recovery Console

First, thanks for your replies!
I just did as whs instructed, and see that the only partition that's active is 199MB *.SYSTEM. So should I now set all of partition active before rebuild MBR?

No you want only the one with the System flag Active.

Now try Rebuild MBR from Disk tab after clicking on HD to highlight it first.

If it fails boot into DVD/Repair CD to run Startup Repair 3 times or until Windows 7 starts.

Good work, illuss.

Did Rebuild MBR work by itself, or did you need to run Startup Repairs?

Rebuild MBR fixed the problem!
I'm really glad I decided to join and get help from this forum instead of HP support forum. So many people are having the same issue as I just did but it seems like in almost every thread I read, HP tech support got them to nowhere.
Thanks again!

In all fairness - the problem you were having can have many causes. That is why a correct answer is not always easy. We were lucky in your case with the MBR. But it could have been more tedious to find the cause of the problem.
