I have a dell optiplex 330 with XP professional sp3 that the user couldn't start because of "missing or corrupted hal.dll". I used the CD to go into the recovery console and used the expand command to replace the ha.dll filel, then the bootcfg /rebuild command. After these, the computer at least got to the windows startup screen but then hangs. I have tried all safe modes and last good configuration options, it always hangs.
I relaunched recovery console and ran a chkdsk /r (took hours!) but the computer still hangs on boot.
I was thinking of re-installing XP from the CD, but this warns that My documents and local setting may well be erased and that is of course where the user has all his data and .pst file so I would love to find a way of getting this computer running again if only to save the data before performing a complete re-install.
Any ideas of other recovery console commands or other steps to try?
