When i turn my computer on a blue screen appears saying.... windows has not been succesfully stared up due to unmounable boot volume it then says ive to delete some hardrive/ software or something and to do this i must press f8 and go to safe mode, but no matter what i do i cant seem to get passed the blue screen can u help?

try to boot to safe mode using F8 key on boot and then recover system or reinstall OS

Have you tried to turn it back on since the incident? Try booting into safe mode (in case there's some sort of malware at work here).

Press the power button and immediately start tapping F8 until you get a menu. Choose "Safe Mode with Networking".

If you are succesful, click the start menu, rt click on computer and select "manage". In the upper right section of that window, click event viewer>windows logs>system and let me know what errors you have. You will see a red circle with an "!" in it. Just click on that and let me know what it says in the bottom window. A screen shot or snippet would be really helpful.

To repair follow these steps:

1. Start your computer by inserting the Windows installation disk if your computer can start from the CD/DVD drive.
2. When the Welcome to Setup screen appears, press R to select the repair option.
3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
4. Type the administrator password when you are prompted to do this.
   
   Note If no administrator password exists, press ENTER.
5. At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.
6. At the command prompt, type exit, and then press ENTER to restart your computer.
7. After you repair the volume, check your hardware to isolate the cause of the file system damage.

Many times this error occurs when I have swapped a hard drive and used the wrong IDE cable to connect it. If your computer uses an Ultra Direct Memory Access (UDMA) hard disk controller, and you use a standard 40-wire connector cable to connect the UDMA drive, you may experience this error. Make sure you are using the correct IDE cable.

Also, if your BIOS settings are configured to force the faster UDMA modes, this error may occur. In this situation, restart your computer and enter the BIOS and load the "fail-safe" default settings and reboot.

If neither of these issues are the cause for the Unmountable Boot Volume, then the issue most likely is caused by a damaged BOOT.INI file in the root directory of the boot drive or file system corruption.

Follow the steps below to correct these file system issues:

1) Start your computer with your Windows XP CD-ROM, or with Windows XP boot disks
2) When the Welcome to Setup screen appears, press R to Repair the installation using the Recovery Console
3) If you have a dual-boot or multiple-boot computer, select the Windows installation you want to access
4) Type the administrator password when you are prompted, if no administrator password is set then just press Enter
5) At the command prompt, type CHKDSK /R and then press Enter
6) Once CHKDSK has finished checking and repairing the hard drive, type EXIT and press Enter to restart your computer

you have the "blue screen of death" i had this same problem and the easiest way to fix it is to take the hard drive out and put it into another computer back up all files you want to keep on it have a boot disk for the right windows operating system on it use the boot disk with it once it is back in the right computer and then put all the files you saved back on it. the blue screen of death occurs when there is a registry error on your computer. if the blue screen of death appears again then you need a new computer.

The blue screen that you see is what they call "the blue screen of death". The error that you have is Unmountable Boot Volume. This is caused by the operating system not being to load due to hard drive errors. This happens due to the computer being shutdown improperly or hard drive problem. I suggest that you contact the manufacturer of the computer so they can try and restore the computer without formatting or changing the hard drive.

chose start windows normaly

hard disk error, insert operating system disks and run a repair or a complete clean installation.

Yes, unmountable boot volume usually means you need a new hard drive. However, if you have a windows xp cd, you can boot to the recovery console (press R at the first prompt) and try running a chkdsk /f command. Sometimes that will help. Thanks and good luck! Oh and if you could remember to give this solution a rating of fixya. Thanks!

To solve this will require more information from you. The Blue screen is Windows way of telling you that it has a driver issue with a basic component, usually your video card. Did you recently make any hardware changes? If so please let me know what was changed.

When windows first boots, you can repeatedly press the F8 key until you see a menu giving you choices of windows booting. You need to select Safe Mode. Safe mode should allow you to at least boot without a blue screen. The blue screen could also be cause by a virus or other software.

Microsoft has a description of Safe mode here;
http://support.microsoft.com/kb/315222
but here is a quick snippet
To use a Safe Boot option, follow these steps:

1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
2. Select an option when the Windows Advanced Options menu appears, and then press ENTER.
3. When the Boot menu appears again, and the words "Safe Mode" appear in blue at the bottom, select the installation that you want to start, and then press ENTER.
