My problem: I had to reformat my hard drive and reinstall Windows XP SP2. 1. I restored Windows onto one partition 2. I used partition magic to resize my partition Everything works fine and I have one half my disk as a partition and one half as unallocated space. 3. I used Acronis TI 9 boot CD to restore a TI .tib file to my unpartitioned space 4. Acronis TI said it finished successfully restoring my file. When I rebooted it said "Invalid partition table" I don't really understand how restoring a TI file to unpartitioned space after the primary boot partition could corrupt my primary boot partition table. Has anyone ever seen this?
