Laptop will not complete boot sequence

Toshiba Satellite C850D-11F, Windows 8.1

My problem: cannot complete boot sequence. This is what happens:
Press Button.
Opening Screen: 'Toshiba Leading Innovation'. (a moving dotted circle appears below the logo).
2nd Screen: 'Your PC ran into a problem and needs to restart. We're just collecting some information for you and then we'll restart.
3rd screen: 'Toshiba Leading Innovation, Preparting automatic repair.'
4th Screen: The screen turns Blank, and remains that way indefinitely.

What I have tried: I was able to enter setup by pressing F1 and I reset all settings to default. Made no difference.bo

First test your HD and RAM, using the disk manufacturer's diagnostic utility, and memtest86+. You'll find both on the UBCD (unless your disk is an SSD, then you must download the tool directly from the manufacturer and run it):

If the RAM and the disk are 100% OK, you can try using Paragon's Rescue Kit which is free, to repair your installation:

That seems like the BIOS.

Follow rindi's advice and test your hard disk and memory.  If that doesn't work then what does F8 do on startup, does it get you into Safe Mode?
Michael MurphyAuthor Commented:
Will follow Rindi's advice. F8 does not get me into safe mode. Give me a few days to run the tests

Also after the tests remove the hard disk and attach as a slave or secondary drive in another computer.  Use that computer to run chkdsk over that hard disk and fix any file system faults that may be there.

Just one thing. Rondo mentioned UBCD
I don't have this. Can I download it.?
Also is there a way to identify whether the disk is SSD I can get into setup. I can also open and look at the hard drive
rindiCommented:
The first Link I posted in my comment downloads the UBCD iso. The manufacturer and model of the disk will tell you whether it is an SSD or a conventional disk.
nobusCommented:
you can open the bottom part, an dremove the disk for checking the model

Is this an SSD drive? Don't understand, but have seen Urls on internet offering to upgrade this model of Satellite to SSD drive. So it looks like mine may be the older drive.
nobusCommented:
this is a regular drive
use the drive firness test :  http://www.hgst.com/support/hard-drive-support/downloads
Michael MurphyAuthor Commented:
I set the boot sequence as follows
1. ODD TSSTcorp CDDVDW SN....
2. USB
3. HDD/SSD Toshiba MQ01ABD032 (S1)
4. LAN  EFI Network ...

I downloaded UBCD and found an older one that I had downloaded some years ago. Ran both and hoped the UBCD menu would appear. However all that appeared was the sequence of Screens I have described in my opening post - ending up in the blank screen.

Then most probably your HD is bad. Bad disks often prevent the booting process from even starting. If you remove the disk, it may be possible to get further and boot from the CD, but that itself won't help much, it will only verify a bad disk.

Do I boot from USB drive same as I tried to boot with UBCD?
rindiCommented:
The problem is the PC won't boot. Remove the HD and then try booting the UBCD.
Michael MurphyAuthor Commented:
I removed the drive and tried to boot from the UBCD.
The result:
Checking Media
No bootable device
Restart system
rindiCommented:
Connect the disk to another PC and try testing it there.

How to connect disk to another PC?
I don't have access to another Toshiba but I'm sure there must be a way around this. I do have a number of Dell PC's and Laptops
rindiCommented:
Just open the other PC, best a desktop PC. They usually have several SATA ports you can connect a disk to. You may just need to get a spare SATA cable if there isn't one available.

2.5" laptop disks and 3.5" desktop disks have the same SATA connections, so they can be easily connected.

>>  Ran both and hoped the UBCD menu would appear. However all that appeared was the sequence of Screens I have described in my opening post -   << this only indicates it is NOT booting from teh UBCD
reasons :
-the old or new UBCD can be bad, or not bootable - so test the cd on another system, to ensure it is ok for booting
-the cd drive, or connection are bad - replace the  drive for testing
Michael MurphyAuthor Commented:
I connected the drive to another PC. I booted from the drive and while the Toshiba screen came up it never completed the boot. It did exactly what it did when attached to the Toshiba laptop, ending in the blank screen. (See my first post)  

I have now booted from the UBCD  and its menu is on the screen. The Toshiba drive is still attach. What tests should I run?

I
rindiCommented:
Under "HDD", "Diagnosis", select PowerMax 4.09 as it should run with all disks.
Michael MurphyAuthor Commented:
Have run one test. There appears to be one block faulty, whatever that means. Test. First few lines ofI attach two screenshots. More to come

Michael MurphyAuthor Commented:
Didn't mean to embed the first screenshot. There is a second, 3.JPG
rindiCommented:
The disk should be replaced.
Michael MurphyAuthor Commented:
This is out of warranty, but I see where Toshiba offer what it calls a 'recovery media' for a reasonably small sum.  Does this reinstall the operating system? If so I might go for it as I can access a replacement disk easily enough.
rindiCommented:
Yes, that installs the system as when you got the PC.
nobusCommented:
you may be able to get the disk working a gain by using HDDregenerator - it fixed many drives for me (not free) : http://www.dposoft.net/hdd.html
Michael MurphyAuthor Commented:
I have it solved. I ran the disk fitness program recommended above and it failed the long test. I then ran chkdsk /f which locates and fixes errors and before testing it also ran a program called CHECK DISK. When I tested the drive it worked and has been working since. Thanks for all of the help which got me there
