Hi!

my Toshiba Laptop can't boot in safe mode, can't boot regularly, cant get into windows. after the toshiba logo at the start, it just leads to a black screen with a flashing cursor. someone please help me.

laptop is a toshiba m305-s4910

OS: windows vista home premium

Tried the hardware recovery thing, which is: press and hold 0, then press the power button, then tap 0 when Toshiba logo starts. That does not work.

Tried pressing F8 to enter safe mode, that does not work either.

both of these things that i tried just leads to a black screen with a " _ " line that flashes at the upper left corner of the screen.
and when i press a button it "beeps" annoyingly.

what do i do know?

thanks in advance!

Microsoft provides a set of tools for diagnosing and repairing Windows, which is called the Windows Recovery Environment, also known as Windows RE. Toshiba provides Windows RE on all computers sold with Windows Vista. It is stored in a special partition, usually 1.46GB in size.

Follow these steps to access the Windows Recovery Environment:

1. Turn the computer on, and immediately press and hold the F8 key.

2. After several seconds, the Advanced Boot Options screen will appear.

3. Use the up and down arrow keys to highlight Repair Your Computer, then press the Enter key.

4. Accept or change the language and keyboard selections, then click Next.

5. Use the mouse and keyboard to select your Windows user name from the drop-down list, and enter your Windows password, then click OK.

6. The System Recovery Options menu will appear. It will include several Windows Recovery Environment options, typically including the following:

* Startup Repair
* System Restore
* Windows Complete PC Restore
* Windows Memory Diagnostic Tool
* Command Prompt
* Toshiba Recovery Wizard

The Toshiba Recovery Wizard option is not part of the Windows Recovery Environment. Select it only if you wish to restore the computer's original factory software 'image' -- including Windows and applications. This procedure first erases all existing programs, documents, and other data on the hard disk drive.

I have this exact same problem.

I am using a Toshiba laptop M505 S4940, running Windows Vista SP2
4GB RAM, Pentium Dual Core processor T4200, Intel GMA 4500M

I had it a little less than 2 years now and this is the first major problem.

Notable events within the last 2 days include:

1)My successful attempt to adjust the size of System Restore file (changed it from 30GB to 1GB using CMD)

2) Yesterday, My version of Spyware Doctor was strangely not working. The active protection was disabled, as well as other features. Within 10 minutes, the laptop randomly shut down on me during the middle of my work and internet surfing. The screen went blank (LED lights still on, power still on) So eventually I held the power button till it completely shut off. It rebooted fine. I performed disk cleanup with CCleaner, and a defrag with WinOptimizer.

3) Today during my internet streaming, I received Trojan warnings on my Vipre antivirus. Then, it cut off, saying that my 'trial' expired,(strangely I have a full version). 2 minutes later, the laptop shut down, the same as it did the day before. However this time it could not reboot.

The screen loads the Toshiba splash screen, only offering you the options F2(for BIOS) and F12(for boot sequence). After this, the screen goes black with a cursor. Nothing is available to load.... you cannot access System Restore, Safe Mode(F8) or anything else [the screen for this does not load]

I have entered the BIOS.. the system recognizes all drives

I have tried using my Windows 7 CD to perform a boot, however, even if i change the primary boot device to CD...the same screen comes up, saying
"CD-ROM Boot Priority.... Boot Ready"



You can't click anything... all you can do is press CTRL+ALT+DEL to restart and face this torture again.

If ANYONE has found a solution..please respond!

hello i have found a solution after about two hours of working on this becuase it just happened to me. your going to have to get another windows 7 disk(illigle one if you want but your going to have to get a keygen activator which you can get anywhere on the internt for free) then put the disk in and hold F12 while its loading. click boot from disk and install it all again. click custom when it asks for it. when it ask for key click do later and it should start installing. when its done your old documents will be under old.Windows. so far this worked for me

I just ran into the same issue as the above guys. Using Windows Vista (not win7). Trying to find a solution. I even unplugged the hard drive and reconnected. IMO it seems like the software on the harddrive is missing the files to start anything to do with windows.

I've tried everything to get into windows and can not.

I created a boot disk/recovery cd for vista and it still won't boot.

I was doing some streaming video watching and all of a sudden my a/v (aviria i think) started going crazy - a program called ptm.exe was running a fake antivirus scan. I deleted ptm.exe and I was unable to access anything on the computer - it couldn't find a program to open (anything). I attempted a system restore but it wouldn't open that either. I shut off - booted into safemode - same issues, couldn't find anything to open the programs with.

Finally I restarted and ended up with the black screen after post with the blinking cursor in the top left.


Any help would be great - when holding down F8 from the time to computer powers up - it just annoying beeps.. no help

OK sounds like I am having the same problem with a Toshiba, with dual core Pentium running on Vista Basic.

Computer has not been used for some time. It was wife's and started having boot up problems. Finally bought a new one and now seeing if I can figure out something on this one, as I have needs for another laptop.

After several attempts finally got :

Startup Repair

Your computer was unable to start
Startup is checking for problems.

It then starts a long list of checks and test it preformed.

Finally one ....
Software installation log diagnsis
Results completed successfull. Error code = 0X0
Time taken = Oms
a blank line or row is next
----------------------------------------------------------
Root Cause Found
-----------------------------------------------------------
A patch is preventing the system from starting
a blank line
----------------------------------------------------
-----------------------------------------------------
session details
-----------------------------------------------------
System disk = \device\harddisk0
windows directory = c:Windows
autochk run = 0
number of root causes = 1


Can anyone make any sense out of this. I am not a techie.

you are gonna have to boot into recovery console, and run "fixmbr" and "fixboot" if this still doesnt solve your issue, then you need to boot to a windows cd reinstall the OS. do a clean install but leave the system file intact without doing a format, this way everything from you last install like my documents and such will all be in a windows.old file, so you will still have them. if you dont mind losing the files then go ahead and format it.

Hello everyone, I'm not a registered member of this site, but Inhave been experiencing the same problems. My computer is a DELL Inspiron 1521 and had this problem occur almost a year ago and just decided to try and fix it. I did a bunch of research on different topics and to make a long story short, thanks to bellomycr, I got my computer working and is fully operational again. It took about 4 hours but don't completely restore your computer because their is a good chance that the hard drive is still operational and can be saved. I would list the solution, but to be honest, the solution just depends on your computer because my solution was a little more complicated. So, if you want to restore your computer to its regular working self, I STRONGLY advise you to get in contact with bellomycr and if you can't then Incan try my he's to help you although I am not as computer savvy as he is. One absolute necessity is Ultimate Boot CD v5.1.1, this is non negotiable. Anywho, If you want to get in contact with me my emails are at the bottom. There is also a way to just get your data files if you want to completely restore it anyway to get rid of any virus's or whatever. Don't give up guys it isn't too late! Thanks again Bellomycr!!!

Similar issue here as the OP. But the laptop boots fine, as long as I don't touch the keyboard. If at anytime, before Windows starts loading, a key is pressed, it will lock up.

That means no F8 menu, no booting from CD drive, nothing.

I have tried a bios update, and the options in the bios are slim.

This is in a Toshiba Satellite A215-S7437.

It's not a critical issue now, but if something goes wrong in the future, it will be.

If anyone has any ideas, let me know!

bellomycr,

I have the same issue with a friend's Toshiba Netbook (NB505) and Windows 7.

I've tried the following with no succes:
- Windows Recovery (pressing F8)
- trying to kick off the Toshiba HDD Recovery process (pressing "0" while booting)
- booting with a Win7 bootable USB Key and trying different restore points
- booting with a Win7 bootable USB Key and reactivating the main partition
- booting with a Win7 bootable USB Key and attempt to activate the Toshiba Restore partition

Hence, finding this forum, I am planning on using UBCD as recommended by you. Do you have any pointers on what I should focus on and which UBCD tool I should consider as the next step?

WOW - Thank you SOOO much!

This has taken the Toshiba from a blank screen with flashing cursor to actually attempting to boot. =)
It now does "Loading RAMDISK image..." and "TOSHIBA Recovery Tool" but then the system runs into another error.

"Windows cannot find 'C:\BIN\BOOTPRIORITY.EXE'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search."

When I click "OK" it restarts the computer and reaches the same error message again.

I am very happy to see that Windows is trying to load, but do you know what else I could do to try and get past this next problem?

Thanks so much in advance!

Feel free to exchange any personal info you like in private messages, but posting such in a thread is a very bad idea and is not allowed so as to protect YOU. And before you say you'll risk it, remember that you are also setting an example. That's why we will remove personal info whenever we see it, and perhaps even do more if that doesn't work.

Most if not all bellomycr's posts to Tom's are in this one thread and on this single issue. Perhaps he or she should post a definitive answer and prevent this necro thread being dragged up every year for the next ten. It is also quite with Forum Rules to publish his e-mail address as part of his Member Website in his Profile. Those of us who do presumably risk being sold to Spammers but speaking personally, I don't see any increase is Spam since joining Tom's nearly two years ago.
