Hello rahul96,

Most probably your recovery area is damaged.  You need a recovery disk or ISO image that you can order from link below

https://support.hp.com/rs-en/document/bph07143

If your country not listed in this webpage. Please contact with HP Support team which related for your end.

Tips: Before order the recovery disk, i would recommend you can do hard drive test via F2 (System Diagnostic) in startup menu.

Thanks,
