Check for a Backup:
Connect the external hard drive or USB flash drive where you backed up your iTunes library to your new computer.
Launch Windows Explorer and navigate to the external storage device.
Locate your iTunes library backup file, which will have the ".itl" file extension. Copy this file to a convenient location on your new computer.
Locate iTunes Media Folder:
Open the Music folder on your new computer.
Right-click on an empty space and select "Show Hidden Files" or "Unhide" (the option may vary based on your operating system).
You will see a folder named "iTunes Media." This folder contains the actual music files organized in subfolders based on artists and albums.
Recover Music:
Open iTunes on your new computer.
In iTunes, go to the "File" menu and choose "Add Folder to Library."
Navigate to the "iTunes Media" folder you located in the previous step. Select it and click "Select Folder."
iTunes will import all the music files from the selected folder into your iTunes library.
Sync with iPod:
Connect your iPod to your computer using the USB cable.
iTunes will automatically detect your iPod and display it under the "Devices" section in the left-side panel.
Select your iPod and click the "Music" tab at the top of the iTunes window.
Make sure the "Sync Music" option is checked.
Choose the music you want to sync by selecting the specific artists or albums from the iTunes library. You can also use the search bar to find specific songs.
Click the "Apply" button to start syncing your music to your iPod.
By following these steps, you should be able to retrieve your iTunes music library and access it on your iPod without needing the original computer or iTunes.
