but if the options allow you can give it a drive letter then you can see it again. usually when in disk management you left click on that partition it will have option, If only option is help, then the partition When you ran the setautofailover command it makes the partition hidden but if when using the F8 you have at the top Repair Your Computer, I don't understand what you mean about boot recovery, your other post said the F8 was working and you could get to advance repair system. I can always do that again, if necessary, because I haven't started "using" that partition yet. It would be perfectly OK if the "OS" partition were to get erased and/or (re-)formatted in the process, since I just (re-)formatted it yesterday and performed a Factory Restore/Recovery onto it. Is there any way to somehow "re-populate" the "DellUtility" partition - either from the supplied Dell "Drivers and Utilities" disc, or from some other source - and make it bootable, as it was originally? Separately, is there any way to make the "RECOVERY" partition bootable, as it was originally? (I also seem to have its files somewhere on the two "System Recovery" DVD's, if needed).

But I'd kinda like to have the "original hard drive(s)" with the "original functionality", if possible. I don't think this is a "critical" problem, because I seem to be able to perform the functions of both partitions using: (a) the Dell "Drivers and Utilities" disc supplied with my system and (b) the two "System Recovery" DVD's that I created - from the "RECOVERY" partition, I guess - when I first set up the system. This is on a Dell Studio XPS 8100 system (now discontinued) running Windows 7 Ultimate Edition, with two 1-TB hard drives configured as a single 2-TB RAID 0 array.

(However, the "RECOVERY" partition still seems to have all of its original files). Both partitions still exist and are their original sizes (41 MB and 12 GB, respectively), but neither one seems to be bootable any more, and the "DellUtility" partition somehow "lost" all of its original files. Through some chain of events that apparently involved installing Ubuntu onto a USB flash drive, the "DellUtility" and "RECOVERY" partitions on my hard drive somehow got messed up.
