with a Gateway Mellinium machine. After I bought a Retail version of ME from them at their suggestion I found out they were mistaken ( or lied, wich I don't doubt) and that they still had the Restore set at somthing like $20.
After using the retail version for a while I found that the badly scratched ME restore discs still worked on the original PC. And are still working. I recall the Retail version wouldn't work until I reset the BIOS at Gateways instruction, wich leads me to beleive the BIOS may only have needed to be reset all along.
In an attempt to avoid scrathing CD's I now make a backup when permitted, and use deep Jewel cases in stead or the slim Jewel cases or CD envelopes.
