Error restore to factory setting using Dell DataSafe backup DVDs

Hi Guys

I have an Inspiron One 2310 which failed to start, but it did pass all pre boot assessments so it looks like disk / memory is ok.

So got out the two DVDs which I made with Dell DataSafe when the pc was new. 

The DVD loads and I go into factory restore - it starts with Formatting your partition and then stops either with error 

Error 0x400110020000100A.

or 

Error 0x4001100200001005.

I can't seem to get any further and now the PC wont even try and boot. Any suggestions - can I get media for Windows 7 from Dell or Windows as I obviously have the license?

Thanks

Simon
