caution:Make sure you have created a set of recovery discs before using these steps. If the system stops responding, recovery discs can be used to perform a system recovery.
caution:Do not delete any files that are associated with system recovery! Do not delete the items: $RECYCLE.BIN, boot, hp, preload, Recovery, RecoveryImage, system.sav, bootmgr, BT_HP.FLG, CSP.DAT, DeployRp, HP_WSD.dat, HPSF_Rep, language, or RPCONFIG! Doing so can prevent a future system recovery from the hard drive. If you are not sure, do not delete the file.
