What the Disk Manager in winXP shows about your disks?
Do you know how to run the xp disk manager?
right click on the "my computer" icon, press "Manage", and choose "Disk Management" in the new window that opens.
You must have a Disk 0, marked as "Basic", something like 147GB, and the partitions with their type, total size, free space, filesystem etc.
Don't afraid to give as much information as you can. Each system can be totally different from another. And, when doing things on the partition and disk system, you needn't hurry. Do a step a time.
In your system, I would first delete the unwanted partition (i.e. f: ), reboot, second reboot, even 3rd reboot, see what win shows, and next I would expand e: in the unallocated space, with all the reboots and checks. I know this takes longer, but I think it is better to control anything as much as I can.
*** It is highly recommended to backup any important files before doing resize/move operations. ***
