After hours of searching and reading this forum I have not found any information to help me with this problem. I have a new Dell XPS M1530 laptop with Vista Premium and a Fujitsu 120GB SATA hard drive. I purchased and downloaded the latest builds of TI Home 11 and DDS 10 (build 2160), installed the products and then imaged by hard drive and created a boot CD. The first problem I encountered was when I first installed OS Selector and activated it. It found one bootable unknown partition but unfortunately as I quickly found out it was the Dell Utility partion. When I tried to deactivate the OS Selector I was no longer able to boot Vista. Thinking the OEM setup of my hard drive was the culprit I blew away the partitions and created one partition for my Vista and left the rest as unallocated. After restoring my Vista partition I tried activating the OS Selector and it comes up with no bootable partitions. Guess what, now I can't boot Vista anymore! A simple restore of the MBR solves the problem but I can't figure out how to get OSS to stop killing my Vist boot files. Ultimately I may want to try and install two other OSes on this computer, possibly XP and a flavor of Linux. Can anyone help me?!
