Hey Guys, Just wondering if someone can help me. I have made an unattended install of Windows XP PRO (OEM), slipstreamed SP3, added drivers, hotfixes and 4 items in the runonce command. I have made the ISO and then burnt it using Nero to a DVD disc (several times now!). However, when I put it into the PC I am working on it just wont boot, even though all the files are on the DVD and it actually autoruns on other PC when in windows. I read that using Burn-at-once helps to make a DVD bootable, but this option is already selected by default. Any ideas as to why it wont boot? Any help or advice will be appreciated
