I forgot to mention that Windows 7 System Image backup on Windows 11 does not support external hard drives formatted in exFAT format. Also the The Windows 7 System Image recovery utility does not recognize external hard drives larger than 2TB. The Windows 7 System image backup tool allows you to use external hard drives larger than 2 TB. Before a system recovery just copy the backup files to the "/WindowsImageBackup/<PC-Name>" directory on a 2TB or smaller external drive. This is assuming that your backup will fit on the smaller external hard drive.
The Windows 7 System Image Backup utility overwrites existing image backup files. If you want to keep different snapshots of your computer, you need to archive the system image backups to a different directory.
Please note that you do not need an external DVD drive to do a full system image recovery. The repair/recovery DVD is used when you can not access the recovery tools in Windows 11. IE. Your Primary Boot drive failed and you are installing a new HDD/SSD drive.
In Windows 10/11, you can create a recovery drive (USB Stick) to replace the recovery DVD.
Just do a web search on "Windows 11 create a recovery drive" for instructions. The USB Key should be at least 16 GB and the creation tool will erase anything on the USB stick.
To Boot from the Recovery USB Stick, Just do a web search on "how to use a windows 11 recovery drive" for
instructions.
