This is more usefull if you have already deleted the System Reserved partition or messed it up some how and now need to delete it from the recovery console.ġ. I could not convert the array from MBR to GPT that is required for disk arrays over 2TB until I got that partition off of there.ġ) Open a command prompt with administrator privileges (right click => run as administrator)Ģ) Open the Disk Management GUI (you could use diskpart for scripts), locate the C:\ partition right-click and select “Mark Partition as Active”, select yes to the “do you want to continue message”ģ) Reboot to confirm that everything is ok.Ĥ) In Disk Management you can now delete the 100Mb System Reserved partition by right clicking on it and selecting “Delete volume”īefore I got the information above, this is how I did it. Turns out Server 2008 R2 installed the System Reserved Partition (100MB) on the RAID array that I setup for DPM 2010 backup storage and not on the mirrored system partition like it should have. Today I went to install System Center Data Protection Manager 2010 from Microsoft and I ran into a problem adding disks to my DPM protection disk pool.
