The system detected a disk volume error which is indicated avery time I boot the notebook. And the system indicates that it can not open some files to do the automatic repair. In additon indicates that windows has detected files corruption on OS(c) and it is needed to check disk error before it can be restore. But I do not know how to check the disk error. I have a operating system windows 7 which was upgraded from windows vista. My computer is Gateway.

This error indicates that the system is not able to find a boot-able device to load the Operating System. It could be something as simple as a disconnected hard drive, or it could even be a corrupt hard drive.

You can check if the hard disk is being detected in the BIOS. The key to enter BIOS in E-machines systems are Tab, Del or F2.

If the hard disk is being detected in the BIOS, it could be a faulty hard disk. You can try booting from the recovery partition by pressing Alt+F10 when starting up the computer. If you're able to get into the Recovery Partition, you can try a recovery, but you might lose all your data. If you're not even able to get into the Recovery Partition, you'll need to get the Windows disc for installing the Operating System again.

If you are seeing 'unmountable boot volume' when booting your laptop / notebook, then this would suggest that the internal disk drive has become corrupted or perhaps has failed. I would recommend downloading a copy of Hiren's Boot CD from http://www.hirensbootcd.org/ - this is a CD image file (.ISO) and needs to be burnt on to a blank CD disc.Boot from Hiren's CD and select DOS programs which will give you access to a selection of Disk tools including HDAT2 which can be used to test and repair bad sectors on the internal disk drive. There are also utilities which can read the SMART data from the drive and give an indication of any problems it may have encountered.

I want to use the short cut to f11 on my laptop as I do on my desk top, how do I use it, my laptop is hp G62

if you still having booting problems, you can do this suggested steps:

Insert the Operating System CD before pc reboot

Try to boot to safe mode with command prompt by pressing F8 repeatedly , select "safe mode with command prompt " option then hit ENTER, then run this command ...

Then follow these guidelines:

Manual steps to run Chkdsk at the command prompt loadTOCNode(3, 'moreinformation');

3. Use one of the following procedures:
   • To run Chkdsk in read-only mode, at the command prompt, type chkdsk, and then press ENTER.
   • To repair errors without scanning the volume for bad sectors, at the command prompt, type chkdsk volume:/f, and then press ENTER.
     
     Note If one or more of the files on the hard disk are open, you will receive the following message: Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.
   • To repair errors, locate bad sectors, and recover readable information, at the command prompt, type chkdsk volume:/r, and then press ENTER.

Hope this help...

your hd is corrupt or missing. Check the BIOS when it boots up to see if a disk is detected. If not, open the computer and check if the HD is there and if it is connected

Unmountable boot volume indicating that the system cannot successfully read the boot sector of the hard drive.
Run the diagnostics on the hard drive, if it fails, replace the hard drive.
If diags pass, boot to the recovery console, run chkdsk /r If it still gives the error after that, you can try reinstalling windows.
If that fails to resolve, then again, replace the hard disk drive

This message is likely to be due to a segment error on your hard drive.

Checking /correcting disk errors
You can use the Error-checking tool to check for file system errors and bad sectors on your hard disk Open My Computer and then select the local disk you want to check.

1. On the File menu, click Properties.
2. On the Tools tab, under Error-checking, click Check Now.
3. Under Check disk options, select the Scan for and attempt recovery of bad sectors check box.

To open My Computer, click Start, and then click My Computer.

• All files must be closed for this process to run. If the volume (drive) is currently in use, a message box will appear prompting you to indicate whether or not you want to reschedule the disk checking for the next time you restart your system. Then, the next time you restart your system, disk checking will run. Your volume will not be available to perform other tasks while this process is running.
• If your volume is formatted as NTFS Windows automatically logs all file transactions, replaces bad clusters, and stores copies of key information for all files on the NTFS volume.

thanks.

This Stop message, also known as Stop 0x24, indicates that a problem occurred within Ntfs.sys (the driver file that allows the system to read and write to NTFS drives).

Resolving the ProblemDisk Corruption. Corruption in the NTFS file system or bad blocks (sectors) on the hard disk can induce this error. Corrupted SCSI and EIDE drivers can also adversely affect the systems ability to read and write to disk, thus causing the error.
Check Event Viewer for error messages from SCSI and FASTFAT (System Log) or Autochk (Application Log) that might help pinpoint the device or driver that is causing the error. Try disabling any virus scanners, backup programs, or disk defragmenter tools that continually monitor the system. You also need to run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owners manual for your computer. Run Chkdsk /f /r to detect and resolve any file system structural corruption. You must restart the system before the disk scan begins on a system partition. If you cannot start the system due to the error, use the Recovery Console and run Chkdsk /r.
rate me if you think its fixya...

regards,

At this point, you can try to clean your disk # 4 and see what happen,
or try to make a copy of disk # 4 (if you can copy the disk) and try again.

or

1) Contact your customer support and ask for a new set of disks.(or only # 4)

or

2) Boot your computer with another OS disk (win XP)

or

3) Boot your computer with some utility disk
