Disabling first seems to be the best way.
There are two reagentc commands. One for the Recovery Tools image and one for the Factory Restore Image. To set the Factory Image as you have in Partition 5, you need to run the command below. If you want to put a drive letter on the partition first, or use the Global path, up to you. Notice the difference between the Tools command /set
reimage and the Factory Image command /set
osimage.
This is for if you put the letter R on that partition.
reagentc /setosimage /path R:\RecoveryImage /index 2
If you want to try the Global Path, use this one.
reagentc /setosimage /path
\\?\GLOBALROOT\device\harddisk0\partition5\RecoveryImage /Index 2
I have been trying to make sure the GlobalRoot path option did not cause some of the problems you show. I have run it on my systems several times without any problems, but use your own judgment.
