I ran into the dreaded hal.dll missing or corrupt error during my Windows ME
migration. I got past it but now need ideas on how to recover my data.

Drive C: 800 MB (System Disk) - No Operating system but is bootable.
Drive D: 80 GB (Seagate Drive) - Original Windows ME system installed
Drive E: 8 GB (blank drive)

I ran setup and attempted to do an upgrade of the system on the D drive.
After scanning the system, converting files and making alterations it loaded
the base setup data and initiated a reboot. At this time I got the hal.dll
missing or corrupt error. After trying some of the less destructive options
mentioned on the forums, I tried to do a new install by booting from the XP
CD to my E drive which I let XP partition and format. This was successful
and I have a mini XP system on my E drive.

My problem is that the data and programs on the D drive are in a partial
state between ME and XP. I have an undo folder with a backup.cab file, a
$WIN_NT$.~BT file with some other data and a user???.tmp file. Ultimately I
want the D drive to contain the XP image and retain the migrated ME files.
Because of the partial installation, there is no ME image to return to. Can
I manually do anything with UNDO that will not mess the working Drive E mini
system? Can I somehow trick the system by copying the known good hal.dll
from Drive E over to the D drive and complete the installation?

I would like to do this without having to reformat and repartition the D
drive. It would be very inconvenient for me to have to try and back it up
reformat and restore. Any suggestions from the group?
