The problem is that Win7 starter to Home Premium is not a supported Upgrade path unless you buy the Anytime Upgrade key, although retail keys do work if inserted in Anytime instead.
I would try a Repair Install using Flash Stick or by transferring the DVD files to desktop to run Setup as Admin. This will reset activation and satisfy the need to have an underlying OS to accept Upgrade key - since a Repair Install is an upgrade over itself. Activate at Computer>Properties link.
If this fails, run a Custom clean install from dekstop also (or boot flash stick) which will see the underlying OS to allow use of Upgrade version key. If not use one of the workarounds here: Clean Install with a Upgrade Windows 7 Version
The best way to write the Win7 ISO to bootable 4gb+ flash stick is to install UltraISO trial version, Open DVD on file tab, Write Image file on Bootable tab, Format button, Write button.
