Toshiba satellite laptop i3 Win 7 Home Premium 32 bit Hi! I tried to read some sense into pages 1 & 2 of this thread but I'm afraid it is way above my head, so I stopped reading.... I have what I think/hope should be a simple request. Without having a clue what I was doing, I used nLite to slipstream SP3 + ?latest SATA drivers onto drive D:\WinXP SATA folder as an ISO file. I want to dual boot XP with Win 7, so that I can use some old XP programs occasionally. My Question: What the heck do I have to do next? by the way, when I earlier tried to install XP onto the Win 7 machine, I got the hung screen with STOP 0X0000007B message. Hope you can help (in words of one syllable, or less....) EdKerm PS If it isn't simple, why isn't it?
