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.
Start Windows, in safe mode, disable "PCI lock" button. TA DA! (sorry its years later
hope no BS tech service robbed you like Bestbuy/Geek Squad seem to do with high praise and a paycheck
