Yes, you can install a new operating system (OS) on an old hard drive as long as the drive on your PC is compatible with the new OS.

Before installing the new OS, you should back up data in the drive and check the new OS's system requirements to ensure your computer complies with all necessary hardware and software specifications.

You usually need to boot the computer from bootable installation media, like a USB drive or DVD, to install a new OS on an old hard drive. The installation process will erase the old OS and install the new one. The hard disk will be erased throughout this process. Therefore, backing up any important files or data before beginning the installation is important.

It's also a good idea to check the hard drive's health status to ensure it's still in good condition and has no bad sectors if you intend to install the new OS on an old hard drive. Hard disk diagnostic tools like chkdsk, smartctl, hdparm, etc., can be used for this.

And if you want to use both Windows 10 and 11 on your computer, you can use the dual-boot method to help you install two operating systems on one computer.

As mentioned above, installing a new operating system, you need a bootable USB or DVD. If you do not have one, you need to create a bootable USB drive.

Under such circumstances, you need to use professional bootable USB creator tools, like EaseUS OS2Go, to help you create one.

It can help create a bootable USB with/without an iso file. For example, you can use it to create a Windows 11 bootable USB from ISO and play a Windows game on a Mac computer. In addition, you can also apply it to install Windows 10/11 without a Microsoft account.

You can install a new operating system on an old drive, and you will need installation media to help you.
