Trying to update from OS 10.1__hard drive selection in Installer greyed out

Question

Was recently given an iMac with a faulty HD. Was able to install a new HD and OS 10.1, but have been unable to update further, because the Installer has greyed out the HD choice in the final step of installation. I am at a loss here. Also the HD is showing as only having about 130 GB available on a 250 GB drive. I doubt the problems are directly related, but maybe one of you would know. I've been stuck at this spot for a couple of days now.

Mac OS X Versions 10.1, 10.2, 10.3, 10.4, and 10.5, are complete system upgrades that must be purchased.
Once an OS has been installed, the point upgrades, such as 10.1.x to 10.1.5 (Final) 10.2.x to 10.2.8 (Final), 10.3.x to 10.3.9 (Final), 10.4.x to 10.4.11 (Pending), and 10.5.x to 10.5.1 (Pending), can be downloaded for free.
Tiger is available for purchase at The Apple Store (U.S.).
Jaguar and Panther, are no longer available directly from the Apple Online Store, as Leopard 10.5.x, is the most up to date OS.
If you know what to look for, Jaguar Full Retail CDs, a Full Retail Version, of the Panther Install CDs, or a Full Retail Version, of the Tiger Install DVD, can be purchased, sometimes less expensively, at some online Apple retailers, Amazon, eBay, FastMac, HardCore Mac, AllMac, etc.
This is the correct one Mac OS X 10.4.6 Tiger, (DVD) Retail, selling for $159.95, at FastMac.
And at HardCore Mac, selling for $199.99.
Notice that both, are more expensive, than, the The Apple Store (U.S.), selling for $129.00.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Jaguar and Panther are only on CDs, not DVDs.
Tiger and Leopard are on DVD.
The discs should look exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on them.

Before upgrading to any OS X version, check to see if your Mac needs a Firmware Update.
If one is required, you must start the computer from a Mac OS 8 or Mac OS 9 System Folder on the computer's hard disk, not from a CD, in order to install it.
Here is the Firmware Update for that iMac model.
Once Jaguar 10.2.x is installed, you can use the 10.2.8 Combo Update,
or if Panther 10.3.x is installed, you can use the 10.3.9 Combo Update, to upgrade to the final version of either OS.
If your Mac meets the Tiger System Requirements, you could also consider installing that, and then use the PPC 10.4.11 Combo Update, to upgrade to the current version.
Jaguar System Requirements
-Power Mac G3 or G4, iMac, eMac, PowerBook G3 or G4, or iBook computer
-128MB of physical RAM
-Supports all video cards shipped by Apple on Mac OS X-compatible systems. Quartz Extreme functionality is supported by the following video cards: NVIDIA GeForce2 MX, GeForce3, GeForce4 MX, or GeForce4 Ti; Any AGP-based ATI RADEON card. A minimum of 16MB VRAM is required.
-QuickTime Pro functionality requires a QuickTime 6 Pro key. The QuickTime 5 Pro key will not work after this software is installed.
-DVD Player requires a DVD-ROM equipped Macintosh with built-in FireWire.
Review these KB Articles, for the Panther System Requirements, and the Additional Panther System Requirements.
The posted RAM System Requirement, for all versions of OS X, is the bare minimum.
For optimum performance, more is recommended.
Additionally, Tiger 10.4.x ships on a DVD, so if your Mac doesn’t have a built-in DVD-ROM player, you will have to use an alternative method of installation.

The Tiger Media Exchange Program, referred to, is no longer available.
There is also a version available on CDs, at FastMac, for $179.99.
