I just read the link too. Bad news.
If it is going to install from a windows 7 install or upgrade disk, You will need to make sure that your DVD drive is first in boot order in your BIOS. Then put in your Windows 7 disk and restart the computer to see if it boots to the DVD. If it does, select the 'FULL FORMAT' option - It may take 2 hours or more, BUT if it works, your full hard drive maybe saved. If it does not, Then like above, Call HP Support and be prepared to spend some time with them.
Option 2: If you Absolutely need the computer nearly Immediately, go out and buy a new hard drive ($40.00 to $50.00) and an EOM version of Windows 7 Home Premium (assuming you have an upgrade version now) (about $109.00) and start from scratch. [EOM version is only good for installing on a completely new drive or one you are willing to format, but it is only about the price of an upgrade version and purchasing a hard drive qualifies you to purchase an OEM as per microsoft] As soon as you are loaded, update from windows update, and if you need drivers for motherboard or video, go to HP site or individual manufacturer's sites, Then install virus software, and your programs.
Good luck.

You could try booting to a Linux disk (not install) and see if you have any access to the hard drive (Linux typically has limited support for NTFS file system)
You did not say if you had any success booting to the Windows 7 disk and if it let you format.
Windows 7 has full support for SATA drives, but not for some older hardware. (did you check compatibility before you started?)

Yeah ive checked that windows 7 is compatible on the laptop. I had it running before, but decided to erase hdd and do a custom instal. But bloody nuisance, never had issue like this before with any laptop or pc. always found software to be faulty. Im going to try a linux boot and dee what happens..... to boldly go where ive never been before!!!!....

Good luck.
Linux can format the hard drive but to FAT32 as well as to native Linux formats. If you get it formatted to Fat32, then your Windows 7 disk should be able to reformat to NTFS (choose full format) and install.
Next time, if you need to, use the Windows Disk and choose full format rather than quick format, and you should be clean to reinstall.

you could always prepare a win 7 boot usb, and boot from that, format the drive, and take it from there.
