Hi guys, Pulling my hair out about this as this worked before and now it doesn't!!!! I either a hal.dll or ntoskrnl.exe error. This was working perfectly on one 500G HD which OS X does not reside on (OS X is on a 80Gb SSD). 1. 150Gb Windows 7 x64 2. 80Gb Windows XP x32 3. HFS formatted for storage of OS X things. Now whichever way I install or partition it XP refuses to install after the first reboot (after it's copied files over). Now i've spent TWO days on this now and still no closer to fixing it. Windows 7 boots and works fine, XP refuses to install even if it's the only thing on the disk!! Any help would be great. Cheers.
