Sorry hear about your health problems hope you get better soon.
It is weird how E: and the D: partitions have Windows XP installed all the folders at root of the E: and the D: partitions are the system folders of the Windows XP. I will show you how to delete those two D: and E: partitions its up to you which one you want to delete but for D: partition you need to do few thing before you can delete the D: partition.
You have to edit the boot menu to remove Windows XP from boot menu.
• In Windows, press the Windows Key + R keys;
• Type Msconfig and click on OK;
• Click on the Boot tab at the top;
• Click 'Windows XP (\windows)', and click on the Delete button;
• Click OK;
• Click on 'Exit without restart';
If the partition is designated as a System partition like with D: partition then in this situation you cannot delete that partition.
• Mark the C: partition as an active partition from the Disk Management Utility;
• Open the Command Prompt as a Administrator and type:
• Restart your computer;
And lastly, delete the partition this will free up space which you can extend to the C: partition with the MiniTool Partition Wizard Home Edition.
• Within MiniTool Partition Wizard select the partition you want to delete;
• From the left pane click on “Delete Partition”;
• Click on the OK button and click on Apply in the toolbar;
• Within MiniTool Partition Wizard select the C: partition and click on "Move/Resize" to enter the next interface;
• Increase the C: partition by dragging the right arrow of the scrollbar to the right or directly entering accurate values in the textboxes below;
• After you're done with the settings, click on the "OK" button;
• Click on Apply in the toolbar;
• Click on the “Restart Now” button on the Notice dialog box;
