    Hi X and welcome to Sevenforums! :)

    Have you tried while booting the laptop to press F8 and select "Last known good configuration"?

    And if you are able to boot into Windows could you please run this and post back:

    X I'm sorry that support isn't coming at the speed of light and we are a limited number of people that know how to solve BSODs. And as we here at the forum aren't really employed by M$ and help people on our freetime as much as we can, so please don't bump the thread and be patient.

    Have you then perhaps tried safe boot on the computer?

    yes i have tried.

    when I load cd of windows with original hard disk sata, is don t show hd for install, but I change hd sata (but fat32) windows istallation show this hd (but impossible install bevause.in fat32). Then if I connect the original HD with adapter usb, it work well on othet pc (I see all partition, system, revovery, sistem reserved).

    I tried also with fix of.mbr but.nothing.

    Hi,

    okay well the very last thing that I come to think off is that there must be some setting inside the BIOS that makes the BSOD appear.

    Usually on laptops to get into the BIOS you would have to press F2 or Delete upon booting.

    What is your laptop make and model?

    Cheers

    Do you have your Windows 7 repair disc? With it you can try to repair Windows.

    Also try to do this tutorial:

    Also check your BIOS for anything with RAID controller, AHCI or IDE.
