After updating Microsoft's firewall I now get a blue screen indicating a critical system driver is missing. I bought a recovery disks from this company, but can not get the system to boot from the CD drive. There is an option to use the f1-f9 function, but the only one that seems to be the right one, f2, doesn't work. I am guessing even a new operating system would not benefit me either at this point. Any advice? Right now I have a really big paperweight
You need to check in the BIOS and make sure the DVD/CD drive is the first device in the boot order, and hdd the second if you want to boot from a disc.
Please answer louis's question, can you boot into Safe Mode?
To boo into Safe Mode press the power button like you were turning on the computer, then immediately start tapping the F8 key and continue till either you reach the Advanced Boot Options or the computer doesn't get that far.
You will need to use the up or down key to move the mouse pointer over Safe Mode, then press Enter.
If you can do this we can try to rebuild the BCD (Boot Configuration Data) which should resolve this issue.
