Hi Baltazhar, I see you’ve put the default for CDBURNER=E: can we assume this is correct for you PC ? If it is then it possible the ISO image you’re trying to burn is larger than the CD you’re burning it to, unlike Nero XPcrerate won’t give you a specific error message telling you this…. of course you can burn the ISO using Nero. The reason for the other error is this: SLIPSPK=YES If you’re not adding any SP’s then this should be NO. I’ve slipstreamed SATA drivers but I didn’t do anything else because my ISO would have been too big. On the general theme whenever I’ve had problems like that ‘unexplained error messages’ epecially after a failure of some kind, I just format the HD & do a clean install.
