Windows 7: Hp pavillion a815n stuck after resizing partition

I was going to partition my hdd it had 72gb free and it has 160gb so i partitioning the hard drive (i used partition wizard) i always use that program.After it finished it reboot then it got stuck at bios it would not load any cd or dvd it will just hang there.
There it says two options "Press F1 to run setup" i press it and says "Entering Setup..." and nothing happens
and "Press ESC for BBS POPUP menu i press it and says "Boot selection popup menu has been selected"
This is what the screen says:

My computer was running Windows 7
My computer is Hp Pavillion A815N

I was trying to resize my partition but it just stopped and got stuck at "Ultra DMA Mode-5, S.M.A.R.T. Capable and Status OK". As i mentioned above I tried to boot of a cd/dvd but it wouldnt work i have 2 other hard drives and the work perfect.

Try this:

• Disconnect the hard drive with your OS on it (the problem one).
• Now see if you can get into the BIOS Setup
• If you now can, then change the BOOT order to boot from CD/DVD drive first. Save and exit.
• Now reconnect the hard drive, and boot from a CD/DVD to test.

This is only addressing the BOOT issue. Fixing the OS startup is another issue that you need to be able to boot from a DVD to work on. Let's see if this works first.

Ok it work!
What do i do next?

Great!

Now you need to repair the Master Boot Record, which I am assuming was corrupted during the resizing.

You could boot with the Partition Wizard bootable CD (you can do that now) and use their tool to "Fix MBR". Give that a try.

Otherwise, use you W7 installation DVD to run Startup Repair. You need to boot from the installation DVD to do this. You will probably need to run Startup Repair at least 3 times to correct everything. See here:

System Recovery Options
Startup Repair
Startup Repair - Run 3 Separate Times

See if that does it!

It looks like the BOOT issue is back once i connect the hard drive.

Is the BIOS set to boot from the CD/DVD drive first?

Is there bootable media in the CD/DVD drive when you start?

Yes to both of your questions.

Btw i dont care if the data in the hdd gets deleted.

Sounds like the hard drive has got a problem.

This is an IDE drive, correct? If you have 2 IDE connectors (Primary and Secondary) on the motherboard, try switching from one to the other and then try to boot. Then switch back.

Double check your connections, try a different molex power connector, make sure the drive jumper is correct and not loose.
Also try going into the BIOS settings and "Restore Defaults" , or similar, on the Exit Tab.

It is a SATA hdd

That contradicts what the BIOS screen says in your first post.
Care to elaborate?
