We have 6 servers, all with Dell Perc 4e/Di raid controllers that we are trying to convert to Hyper-V. They all fail with 'Error Loading Operating System'. The only thing I can see within disk manager is a 4mb unallocated section of the drive on all six machines. Other servers with Perc 5 and 6 convert OK, but all the drive is used. For a trial are we OK to allocate the 4mb a drive letter and format to see if this portion is confusing the conversion? Is the 4mb there for a reason.
Thanks Paul
