How do I downgrade from windows 8.1 back to windows 8?

If you can get your hands on a Windows XP cd, it will partition and format the drive for you allowing you to install from scratch. You would then just plug in the license key from the sticker on your laptop. As far as the recovery disk on the original CD, there might be an option on bootup that would have you push an F key to access it. Or you can usually order them online. It's not too hard to get the drivers you need from online so I would just go with any XP disk you can get your hands on. You'll be using your own license so you can even borrow one.

I think either you will have to make sure that your drive, your cd drive, is booting up,It should be f2
to boot your computer, it will give you a selection to boot from, your cd is the correct selection.,if no results,you must have deleted the backup partition or recovery partition when you erased the partition.Drive eraser would do that most likely.it writes over your drive so software is unrecoverable it is a security measure for valuable files not to be seen or stolen thanks kawuna

Hi. Once I had this similar problem with a HP Pavilion dv9000. "No Operating System"; "Windows Recovery Console cannot continue because there's no HD present..press F3 to Exit". No progress with Safe Mode nor Command Prompt, etc.
Then I went to the Bios, change tab to "System Configuration" and change the "Sata Native Support" to disable, whitch says that by changing to disable the HD would work better if the Operating System are Win2000 and Win9x.
Hit "Safe and Exit" and the computer started normaly!
I relly don't know how or why. It just work.
I don't know if would work for Linux (mine had Windows XP) and don't know the Bios view of your laptop. But you can explore and give it a try.
Hope this helps.
God Bless You!

if you download the sata drivers from the toshiba website for your specific laptop and then extract them and get nlite ( www.nliteos.com and slipstream the drivers into the xp disc you can then re install xp and it should allow you to boot.

As for the hard drive frozen password that should be in the bios on the hard drive that you set it for so it should remember it

if not you may have to contact toshiba and they should have a back door password that they can produce once you give them the asset tag ( serial number of the laptop ) and once you enter that it should resolve the hard drive frozen issue.

Had a hard drive frozen at a school once and had to call dell ( as it was a dell laptop obviously ) and gave them the serial number and they created a back door password for me - jobs a good one :D

Do the following without the battery inserted.

Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...

Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.

These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.
