I'm a computer novice and recently just installed a new dvd writer reader, but when I tried to boot again after installing I got a completely blank screen with a repeatedly blinking black line at the top left corner. After fiddling around for long enough I figured out that disconnecting my external hard drive caused it to instead give me a disk boot error message asking me to insert system disc and press enter. I tried reverting back to the old disk drive but that doesn't work either. Help me!!!!
Check that your internal hard drive is the highest priority boot device in the BIOS (usually Advanced CMOS Settings)
I did, and it is... A new wrinkle has shown up... my dvd rom and hard drive don't reliably show up in bios... sometimes they're there sometimes it's gibberish, sometimes it's nothing....
Sounds like something is faulty. Try unplugging the new DVD drive first, and then try a different cable.
are both drives if ide on the same data cable? if both on same data cable, are they jumpered the same as master, slave or cable select?
