Every now and then I have to show everyone how dumb I am!! I am in the finishing stages of installing a new shuttle AK32E. I also decided to put in a new Hdrive and a fresh install of Win 2000. It booted to the W2K cd, did the format, but got to a point where it said it could not find or install a certain file. I did an "escape" the install when I meant to "skip" that file and worry about it later. But now it will not boot off the CD again. It will boot from the A drive. But without a disk in the A drive I get a message to the effect "NLTDR is missing....press ctrl Alt Del and try again". And it just keeps going thru that sequence. Doesnt matter if I change the boot sequence in the BIOS....will not go to the CDrom. I guess my question is what is the NLTDR ?? Any help greatly appreciated. THANKS!
