Pro tell me the latest verson of dos and dos command and ho to use it.

Run the check disk utility.

To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.

In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.

If you can somehow get to a dos prompt (black screen with white writing) then you can fix it without a repair disc or system disc. If not, just borrow a Repair Disc or Operating System Disc from a neighbor, friend, family member or co-worker. Just make sure that the disk is the same as your operating system. Look at your Certificate of Authentication (COA) Sticker that is affixed to you laptop. Most times it is on the bottom or inside the battery compartment. It will tell you which operting system you have and it will have a series of 5 letters and numbers which is your product key. If you have Windows Vista Home Premium, or Windows 7 Home Premium, or Windows XP Professional, then borrow that type of operating system disc or repair disc.

You will need a operating system disk or a repair disk to fix it. Insert it in the drive then boot from it. You want to get to a dos command prompt (black screen with white lettering) and type the following commands. Press ENTER after each command.
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd

Reboot and see if the problem is solved. If not get back to the dos command prompt and run the check disk utility.

To enter in to bios, try password Toshiba.

Also:
By UsingMS DOS Command: This methodworks only if you have access to the system when its turned on because thismethod requires MS DOS. Open Command Prompt from Programs menuand provide following commands one bye one: Debug o 70 2E o 71 FF quit NOTE:The first character in the above commands is English alphabet "o"and not the number 0. After providing the above commands, restart your systemand it should reset the CMOS Settings along with the BIOS password. If you arecurious to know how it works? then let me explain the above commands: In this method we are using theDebug tool of MS DOS. The "o" character present atfirst in these commands, outputs the values to IO ports. The number 70and 71 are port numbers which are used to access CMOS memory.By providing FF value we are telling CMOS that there is aninvalid checksum and it resets the CMOS settings as well as BIOS password. By UsingSoftware: There are a few software which canalso reset CMOS settings or BIOS password or both within a few clicks. But asstated above you should have access to a system which is turned on and shouldhave access to MS DOS or MS Windows: CmosPwd . You can download program on this page: http://www.cgsecurity.org/cmospwd-5.0.zip

The Mac does not have a DOS mode to turn off.

It does have a command line mode called 'Single User Mode' where UNIX commands can be executed. Get into SUM by holding Command S at startup.

To go back to the Mac OS X interface, type 'reboot' and press the Return key.

Hello,
There is a perfect solution for your problem:
Either format or downgrade to xp pro.
You could always install DOS 6.2 although you are going to use DOS prompt and type the commands instead of pointing with a mouse.
