Mogens, Thank you for the quick response. 1. Software raid 2. The problem of boot not completing and apparently looping through an error path was a function of the boot drive only. The error was that some function was running to fast and was being retried over and over. The boot process,when started, proceeded through the locating and loading of the LVM setup. The failure begain right after that. 3. Yes, however at the time I didn't fully understand how to use it. I just tried it out and, sorrowfully, will be able to use it next time. 4. My system has 1 500Gb SATA drive for boot and Linux basic directories. My personal information is located on two 500Gb SATA drives in a Raid 1 array. Using the F10 dist install disk I selected only the boot disk and reloaded F10. Then reconstructed the Raid 1 array, which I have done successfully several times, and then added the two Raid drives back to the array. They then equalized, which appeared normal, this took several hours. When that finished I checked for data/directories and there was nothing. By nothing I mean no directories, no folders, no data. All though F10 detected that they were Raid formatted (ext2). So my only disaster is the seeming loss of some very important stuff. I've been a software/systems designer for a long time so even that shall pass. I hope this helps. Again thanks for you help.

Can you boot from the installation CD/DVD in rescue mode? How do you see that the data drives are blank?
