I was attempting to speed up the boot process in my Dell Quad core computer. I went into MSCONFIG / advanced and selected 4 processors and then checked the PCI lock as well upon restart I am locked out of my computer now. It starts to boot up then it dumps to a blue screen flash then reboots to repair mode which by the way does nothing. Ive tried my Emergency boot disk and that didn't work. I have long since installed UBUNTU as a second OS on the partition to save my windows partition and to access my files.
I would like it know if there's any way to go in and reverse those actions and have it boot properly again.
