Hi there mlr99,
I recommend you download and install Stellar Volume Repair application which is a Mac disk repair software. This software will help you create a bootable media with which you can boot up the Mac and repair Macintosh HDD (startup drive). Additionally, it enable Journaling on Mac volumes. Mar 24, 2020 Disk Utility can find and repair errors related to the formatting and directory structure of a Mac disk. Errors can lead to unexpected behavior when using your Mac, and significant errors might even prevent your Mac from starting up completely.
From what you describe it sounds like you are trying to install Lion on your newly installed HDD replacement but its not showing as a disk when you try to actually install Mac OS X. That indicates to me that the drive has not yet been formatted as Mac OS Extended Journaled, so it is not ready for Lion to install onto it. This section of the following article will help you get that drive erased and formatted properly so you can continue with the installation:
Mac OS X comes with an easy-to-use application, called Disk Utility, that allows users to verify and repair hard disks using a graphical user interface and it is recommended for most Mac users that are not comfortable using the terminal. However, this can also be performed using the command-line. Startup 9.2.1 repairs problems that may occur when Mac OS 9.1 and Mac OS X are on the same partition and a version earlier than Startup 9.2 has been used.
- Before you begin, make sure your Mac is connected to the Internet.
- Restart your Mac. Immediately hold down the Command (⌘) and R keys after you hear the startup sound to start up in OS X Recovery.
- When the Recovery window appears, select Disk Utility then click Continue.
- Select the indented volume name of your startup disk from the left side of the Disk Utility window, then click the Erase tab.
- If you want to securely erase the drive, click Security Options. Select an erase method, then click OK.
- From the Format pop-up menu, select Mac OS Extended (Journaled). Type a name for your disk, then click Erase.
- After the drive is erased, close the Disk Utility window.
- If you’re not connected to the Internet, choose a network from the Wi-Fi menu.
- Select the option to Reinstall OS X.
- Click Continue and follow the onscreen instructions to reinstall OS X.
