Trying to install Server 2008 (x86) to a Dell Dimension 3000, with 2 GB RAM and 40 GB HDD (above the minimums, according to the Help notes). Using TechNet Plus Evaluation disk 0429.07 March 2009.
Machine has a copy of SBS 2003 on it that I intend to overwrite. I'm quite sure I'm selecting that option, so as not to be limiting the 2008 installation to the available space.
At step 2 of the installation, it bombs out with this messge. "Windows cannot install required files. Make sure all files required for installation are available and restart...." Error code 0x80070070.
