Windows will not start - can't do a clean install

Hi all:
I've been trying to figure this problem out for several days. I would appreciate any advice. My problem started after running Chkdsk overnight. It said I had some errors that it tried to fix. After I tried to reboot windows, It did not start. I got
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM
No bootable device ----

So I googled this and saw that a lot of people have had this problem. So I went into BIOS checked the boot order, Then I tried to do start up repair. It would start loading window files, then nothing but a black screen and a large mouse pointer. I then tried safe mode, again a blank screen with the only the words safe mode showing and the large mouse pointer. I then tried to get into recovery, but I couldn't.
Next I removed the hard drive then re-installed it. Same thing. So I thought the hard drive failed, so I downloaded Parted Magic and made a bootable disk. I changed the boot order and it loaded it into ram and it worked fine. I used it to copy my data to a usb drive and then ran the hard drive test and it passed. The GSmartControl show that that there where errors that occurred at start up it. I then ran the System Stability Tester and everything seemed fine.
I then downloaded Mentest86+ and burned the iso too a disk. Again I booted from my cd/dvd drive and Mentest 86+ ran and the computer passed. So I figure that my hardware was ok.
So I downloaded a Windows 7 Home Premium iso and burned it with ImageBurn to a DVD then verified it. I figure I could try to use it to fix Windows or worse case re-install it. I put it in the optical drive restarted the laptop. It said loading Windows with a white progress bar along the bottom of screen, then nothing but the black screen with the mouse pointer. So I downloaded Rufus and made a bootable USB drive of the Windows 7 iso. Same as what happened with disk.
Anybody have any ideas? Should I wipe the drive the try to install Windows?
Thanks in advanced,
WM

I got the Windows 7 link from PC magazine. I just wrote the iso to disk after it was downloaded, with ImageBurn. Was there anything else I needed to do to make it start? If my disk is shot why could I run Parted Magic? I was able to get my data off of it and the stress test had the system running hard.

Test the HD with the maker's HD Diagnostic extended CD scan, followed by a Disk Check from the Win7 installer's Command Line in System Recovery Options .

A checklist is here for everything else that can be done for Troubleshooting Windows 7 Failure to Start.

Everything needed is here to get and keep a perfect Clean Reinstall - Factory OEM Windows 7.

Use the latest official installer in Step 2 for your licensed version, burned to DVD or stick using tool in Step 2. If these still won't boot then reset your BIOS to defaults: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. If this doesn't work then unplug your HD to see if it's blocking OD and Flash stick boot.

If you have a UEFI BIOS you'll need to confirm the settings for UEFI, Legacy BIOS or CSM depending upon whether you installed to UEFI BIOS vs. Legacy BIOS.

How do I knoww if I have a UEFI BIOS or a Legacy BIOS? I have a Toshiba Satallite A505-S6005 with an Intel I3 and a Mobile Intel HM55 Express chipset. I think I bought it in 2009.

Thank You! I will download the ISO from you link, then try the other suggestions tomorrow, for it's late now.
