Hello --- If I got the scenario right, have you tried exporting the whole
PST file and re-importing again? I do this everytime i change drives,
re-configure RAID, etc. It works.

Also, the problems being faced during installation could be due to
inconsistencies on the hard drive. Execute CHKDSK /F. Experiment with the
LIS (local installation source) utility available on the microsoft/downloads
site.
