Windows 10: Format C Drive and Restore From Backup

Version 1809 (OS Build 17763.1217)

Hi, I have an issue where an older version of a program must be uninstalled before the new version is installed.

When attempting to uninstall the old version, it did not complete properly. As a result, most of the files are still there, but now I am unable to complete the task because it does not show up in the list of installed programs.

I tried deleting the program folders and reinstalling, but it thinks it is already installed and will not go further.

I cannot run the new version because it will crash.

I am thinking of formatting the C Drive, and then restoring everything from backup.

Is this a good idea?

Is there a better way?

Thanks for any help.

Free hard drive backup/restore program?

I am looking for a free (freeware) program that will back up and restore a hard drive. I'm looking to clone a few external hard drives. If the program will backup the used space instead of the whole drive this will be awesome! Thanks for any suggestions.

Obviously you're looking for something besides your Xp Pro utility that does this?

 

How to restore C: drive from backup?

Thank you. I'll try your suggestion if my next attempt fails. I think my problem has been that I have been using a disk/partition backup instead of a system backup file.

- - - Updated - - -

Tried to recover from last System Backup file but it failed, too. Although it took a long time (from NAS backup), the recovery successfully completed. But the used size of the C: disk was very low and no OS was there. I have been using a USB that contains the Windows Installation Media, and when I boot from it, I select the UEFI version in the BIOS boot menu.

Here's latest attempt info:
Using Command Prompt, I cleaned Disk 0 (C: Drive), where the OS should be, and converted it to GPT.
Reinstalled W10 using USB that contains Windows Installation Media. I selected the UEFI version of the USB in the BIOS boot menu.
After Reinstall, DiskPart, (List Disk, Disk 0 is GPT), (List Volume, Volume 3 is Boot), (Select Volume 3, List Partition, 1=Recovery, 2=System, 3=Reserved, 4=primary)
Rebooted from EaseUS Emergency disk, using the UEFI version of the DVD in the boot menu.
Restored Disk 0 (C: ) from EaseUS partition backup of C:
After restore completed successfully, system rebooted itself.
Error – No operating system found.
Rebooted from USB Windows Media. Went to Repair mode, Troubleshoot, Command Prompt
DiskPart, (List Disk, Disk 0 is GPT), (Select Disk 0, List Partition, Only 1 partition, Primary)

What am I missing? After the EaseUS restore, only 1 partition was created on Disk 0. The C: drive appears to have all of the files.

Thanks for your help.
