How to Restore Utility Partition of DELL desktop

Hello everyone,

I have a DELL inspiron 530 desktop with Windows Vista Home premium(32 bit version)................

I had re-installed the Windows Vista Operating system Using the Windows Vista DVD provided via DELL from microsoft instead of using the DELL factory image restore feature ............ after somedays i used the DELL factory image restore feature to restore my desktop to the factory image ................... the process got completed successfully .....................

after sometime for the troubleshooting purpose i wanted to run the DELL diagnostics Utility feature using the Utility partition provide on the HDD ...................

So i rebooted my system and while the BIOS was loading i pressed F12 to get into the Boot Menu options list .............. which lists all the booting options including Utility partition .................... then i selected the Utility partition from the list and pressed enter ........ then a message was displayed :--

"Booting from the Utility Partition .............."

but after that nothing happened and i had to restart my desktop ............... and i then repeated the same procedure but again nothing happened except for the message getting displayed .......................

so is there a way i can recover or restore my utility partition of my inspiron desktop ..........

thnxx in advance ...............
