This error occurs due to a malfunctioning system hard drive. The text of the message explicitly states “UNMOUNTABLE BOOT VOLUME”, which can only mean one thing: there is no way to mount (connect) the boot volume, that is, the disk on which the boot record is located.
Immediately, on the death screen, the developers advise trying to reboot the system, reset the BIOS settings or try to boot into "Safe Mode" and restore Windows. The last recommendation may well work if the error is caused by the installation of any software or driver.
But first of all, you need to check whether the power cable and data transfer cable have departed from the hard drive. It is worth trying to replace the cable and connect the HDD to another connector coming from the power supply.
Method 1: Restore in Safe Mode
You can load Windows XP into Safe Mode by pressing the F8 key at startup. Before us appears an extended menu with a list of possible actions. Use the arrows to select “Safe Mode” and press ENTER.
When loading, only the most necessary drivers are launched, which can help in case of malfunctions of the installed software. After starting the system, you can perform a standard recovery procedure.
Method 2: check the disk from the recovery console
The system utility check disk chkdsk.exe is able to repair bad sectors. A feature of this tool is that it can be launched from the recovery console without booting the operating system. We need a bootable USB flash drive or disk with a Windows distribution.
Boot from a flash drive. After loading all the files on the start screen, start the recovery console with R. Choose the operating system you want to log into. We have one system, enter “1” from the keyboard, then write the admin password, if the console requires it. Next, run the command chkdsk /r A rather lengthy process of checking the disk and fixing possible errors will begin. After the verification is completed, you need to enter the command exit to exit the console and reboot.

If this does not happen, then the hard drive needs to be more thoroughly checked by specialized programs, for example, Victoria. The saddest outcome in this case is a non-working HDD and loss of information.
