"USB ports in the boot sequence BIOS. Simply enter the BIOS setup and remove USB devices of the boot sequence: (boot sequence) "
Put the error message into google for more ideas. Sorry but I've found this one to never have the same two solutions in a row. Must be some dozen causes.
And was that a CLEAN install?
I have an Acer Aspire One which had windows xp. I upgraded to windows 7 and now I keep getting a blue screen which says bad pool caller or bad pool header. It happens randomly when using the internet and sometimes when shutting down. I tried reloading windows 7 which I think made the problem occur less, but it's still happening. I used a program called win to flash to create the bootable windows usb drive, could that be the problem?
I tried reloading the graphics driver but that didn't help. Could the problem be caused by the boot sequence? I had to modify it so it would boot from the usb, but I don't know if I have it back in the correct order.
