However, if you are unable to do so then you should use a third-party data recovery tools to recover the trapped data.

Consider a scenario wherein you are unable to start your Windows XP system. An error message is getting displayed, that is:

“Unmountable Boot Volume”

Cause:

There can be following causes for the aforementioned error message: The system drive is corrupted and, thus, is unable to be mounted. You are using a standard 40-wire cable instead of the 80-wire, 40-pin cable to connect the UDMA (Ultra DMA) drive to the controller. The BIOS settings are defined to impose the faster UDMA modes.

Resolution:

To resolve the aforementioned error message, you should perform the following methods, not in any specific order: If the system drive is corrupted, you should perform the following steps: Insert the Windows XP CD-ROM in the disk drive, and restart the system. Press R to start the Recovery Console when the 'Welcome to Setup' screen is displayed. Select the drive for which recovery is to be done. Enter the administrator password, when prompted to do so. Enter chkdsk /r, and press Enter. Enter exit, and press Enter. If the error is because of the connector cable, then you should replace the 40-wire with an 80-wire UDMA cable. If the error has occurred because of incorrect BIOS preferences, then you should load the 'Fail-Safe' settings. Then, reactivate the most frequently used options.

These aforementioned methods should be able to resolve the issue. However, if you are not able to address the situation then you should use a third-party data recovery software to recover the trapped data.
