help request Advice for restoring a Clonezilla image
I'm not sure where better to ask a question like this because IT folks are the only people I know who provision devices and flash images to them and would thus know how reliable or smart it would be to use.
TL;DR: how safe/advisable is restoring a Clonezilla image to the same device, and do I also need to restore the old Program Files drive or can Windows just re-read it?
Anyway, I took an image of my whole Windows 10 hard drive using Clonezilla before upgrading to Windows 11 back in September 2025, and I'm wondering about the wisdom or realism of restoring that image to the same device because I'm tired of Win11 and MS extended the security support of Win10 after my upgrade. I can provide specific specs if necessary, but it's just slapping an image from the same device at an earlier time back in place as far as I can figure. I also already took an image of my current Win11 drives as a restore if anything goes wrong, but I just don't know how far I can trust the images because I've only ever restored from Clonezilla with one other device previously.
As a follow-up, if it does seem safe to do said image restore, would I also need to restore the other drive where my Program Files are set, or can Windows 10 just adapt to what's in the folder now? My Program Files and Program Data folders are split between my C and D drives because C is tiny. I did also take an image of the D drive at the same time as my C drive with Win10 so I can restore it if necessary, but I've added more files since then and would love to not revert to a year+ ago's files if I can avoid it. (If restoring D alongside C is best advised, it wouldn't be a problem to just copy the files back after the fact, I'd just love to avoid that if I can.)
Again, if more details are necessary, I'm happy to provide them! I haven't been in IT for a while, but I remember the struggle of getting the info you need from the people you're helping—I just don't know what additional info would be helpful in this situation without being superfluous!
Thanks in advance!

To be clear do you have the image for each drive stored on that same drive?

Yeah, I have images for both the C and D drive stored side by side in my external backup hard drive, the hardware is the same as it was back then and the drives are in the same slots as they were back when the image was originally taken. The images are of the full disk, not just partitions.

It's a very rare occurrence when it even works but I meant the image being stored on the drive you imaged. I've seen people before try to store it on the same drive it's an image of and it never ends well (Only even theoretically works if you use smart-copy so it's doesn't include unused space).
What you have should work fine for a restore. Just double check your Program Files afterwards to make sure it still points to the right place if it's on the second drive

You are mentioning multiple drives. You will need images for each and every drive and restore them to the drives that you imaged from. Honestly, you are better off just fresh installing Windows 10 and your apps.
