I am having problems with my Dell Inspiron 8600, which runs on Windows XP home edition. Windows will not boot up, saying that it is missing a dll file. I've attempted to do a Repair Reinstall following the guide provided by Dell support. After getting to the Windows XP Licensing Agreement page, I select "I agree." However, the next screen is very different then that of the guide, stating: "The following list shows the existing partitions and unpartitioned space on this computer. Use the UP and DOWN ARROW keys to select an item in the list. To set up Windows XP on the selected item, press ENTER. To create a partition in the unpartitioned space, press C. To delete the selected partition, press D." I do not want to install over my old files, since a lot of it is vital to my business. If anyone can suggest a solution to this problem, I would be very greatful.
