Hello, I know my problem is PC related but I use this forum for my mac And I think is great plus I am really deperate I hope someone can help me please!! I just bought a wonderful new desktop pc from dell with the WONDERFULL windows vista. unfortunatly it may be wonderfull but it doesn't support protools. therefore i have been trying for the past 6 hours to: 1: install windows XP (I have an original windows XP which I bought with another dell PC). that doesn't work beacause a window come up saying that the version of windows that i have already in my computer in newer and it cannot let me install windows XP. it also says look for solution on line. 2: I decided to reformat my hard disc with the w XP CD. I boot the computer from the CD drive but after is loaded a blu screen appear saying that windows cannot start/install/load because of an error. it says check for viruses or check that your newly installed hard drive has been properly configurated and terminated(???????) 3: I tryed drastinc measures with killdisk.com I burn a executale disc following all the instructions from the website and boot the computer with that disc. but that doesn't work either. the black computer stops with a starnge code and doesn't do nothing else. in the website they say that killdisc run with all the windows version including XP but they don't mention vista. maybe it is not made to overcome vista. i don't know. ps: obviously I tryed to reboot with the windows vista cd. but that does't give me any option at all (format disc) a part from repair windows. it doesn't need repair it new untuched and it has never been connectet to internet so no viruses possible. it is just brand new from dell. please help me please!!
