After reviewing again your entire post: I believe your easiest and most successful course of action would be to perform an Acronis TrueImage Restore using the Acronis Rescue CD. This allow you to begin anew with a working system. Put the 25GB drive back in its original position. Remove the cloned drive. Use TI's restore feature and restore your D drive backup mentioned in post #30. In other words, restore the backup of D (250GB) overtop the current Drive D (250GB). At the screen labeled "Partition or Disk to Restore" Do NOT tick the Disk option, tick only the drive D option. Drive C should not be listed. Note in addition the listing of drive D, does it also list a "Track 0 and MBR" option? If yes, as you proceed thru the various screens, one will be the titled "Next Selection". Tickmark "Yes I want to restore another partition" and TI will return you back to where you can now tickmark the "Track 0 and MBR" option. One of the nice things about TI is that it enables you to practice or simulate all the different functions including the restore function. It is practice or simulation up to the screen where you click "Cancel or Proceed". At that point, you can cancel and return to main menu for more practice; or if you click proceed, the actual operation will commence and cannot be cancelled once it start. However, before you begin your practice simulation, download this pdf about "Partition Resore with Resizing". http://grover.tabinc.com/gh-temp/gh-acronis-part-resize.pdf You can ignore the pdf part about partition resizing but it shows how to pick Drive D and Track 0 with mbr. etc. This will help answer any questions you have during practice. After practice, should you have more questions, get them answered before you perform the actual restore. Do NOT have the 500 attached during this operation. You do not want Windows to see two versions of Windows! Do NOT attach the 500 until your first successful bootup. Once you get your old system back running normally, we can help you (in a new thread) get started on a right track should you want to repeat your cloning procedure. -------------------------------------------------------------- PS: So others can help understand, would you edit your posting #50 about drive letters. The first column is confusing. I don't believe you have 5 partitions on one drive. You can use dashes or underline or periods to act as spacers under your column headings. Add disk number; partition number; and disk size to beginning of each line such as Disk1, partition 1, 500GB...NTFS.....G....C....Empty Disk1, partition 2, 500GB...NTFS.....M....D....System What is the FAT32 partition?
