Remove all usb flash drives or external hard drives connected to the laptop.
If no flash drives or external hard drives are present the you will need to reboot your system and press the delete key repeatedly until you get into the BIOS. Once in the BIOS you will need to locate boot disk priority. Set priority 1 to the laptop's main drive and priority 2 to the CD/DVD drive.
Now it should first try boot on your hard drive with your operating system on it. If after this you still get the unmountable boot volume error then your hard drive may be corrupt.
Please download and Run the BIOS update utility for resolve this issue. You can download it from the link below.
If the problem still persist, reboot the Computer and keep tapping the F2 key when VAIO logo appears on the screen to enter BIOS mode. You can manually disable the function System and BIOS Shadowing. This will resolve the issue.
If you receive the “unmountable boot volume” error and have an installation disk, you still have a chance to save your system.
1. Insert your XP installation disk into an optical drive and boot up your computer. 2. When you see a welcome screen, hit the R key on your keyboard. This will enter you into recovery mode with a DOS prompt. 3. Now type chkdsk /p and hit Enter. This will launch a utility which will check for errors on your hard drive. 4. After the process is done, type fixboot and hit Enter to repair any damaged boot files which may have become corrupted. When asked to say yes or no, type the Y key on your keyboard. 5. Type exit and press the Enter key to reboot your computer.
If all went well, you should now be able to boot back into Windows without a problem!

The Error 0270 means you must replace the lithium coin cell battery. Google "Thinkpad (your model) support" and read the manuals for instructions.
With a new battery installed, boot into Setup by pressing the F! key. Reset the clock and verify that the hard drive is recognised.
Reboot, all might be OK. If not, download and run IBM's free PC-Doctor utility to test the machine. If all is OK, I suspect the hard drive was stripped and an operating system must be installed. Verify this with a DOS boot floppy. Run FDISK to view your partitions.
