A lot of people have boot problems caused by bootskin. In the information I found, which spans 2005 to 2008, there's a driver named vidstub.sys which needs to be removed before bootskin can be uninstalled. For starters, see if you have this driver at C: \windows\system32\drivers\vidstub.sys
If you find it, rename it vidstub.zzz and then see if you can restart the computer. (All forums say to delete this driver, but I'm cautious when it comes to deleting drivers.) If you are able to rename it, try to uninstall any versions of bootskin you have. It may be necessary to use a boot disk to get to this file.
See this thread at Stardock Forum, where there is a discussion that goes into 2008 with regard to this one driver:http://forums.stardock.com/91272

Hope this helps.
