I'm having a similar issue to this. OEM disc, service pack 2c. I do have a working slipstream with a hotfixes pack from here and the AVG, Firefox and IE7 addons installed. Since trying to get hotfixes: KB890830 KB933360 KB937143 KB938127 KB936357 into the mix, I haven't been able to get an ISO that I can install. I'm able to do the text part of the installation, then when it reboots to the GUI portion of the setup, I get the blue background, mouse cursor and then it reboots and gets stuck in a loop. I'm going to try and get a working one without the 5 above hotfixes slipstreamed in and include them in a folder on the CD instead, or perhaps use the 'run once' function. If it does, I'll let you know and you can leave those ones out if you're including them.
