I have a real headscratcher here...
I am making a uniform image for about 15 Dell Optiplex 360's. I am using Macrium Reflect to make the image and restore them with the uniform image. I couldn't use the UNIX based boot disk because of the SATA drives in the Dells, so I created a Universal BartPE Boot Disk Option and added the Macrium plug in. I started with 6 machines and everything went according to plan as far as booting them, getting them to the network share and getting to the image and starting the image recovery download. However, out of the first 6 machines I did this with (using one boot disk and taking it out during the network image download process and moving to the next one) only the first and the last were MOSTLY (and really actually if not actually, technically) successful.
The first and last two got stuck at 99% and the BartPE and Macrium were unresponsive (even though I had replaced the CD in the drive before touching or clicking on anything). However, I was able to hard re-boot them and they booted into the new image just fine and are off to the races.
All the other ones, however, got stuck at somewhere between 33%-48% and were hardware locked (or became so soon after trying to click on anything). I understand they got half an image and will not boot to the image...that's fine. But they will not boot to the BartPE disk either!
