No bootable drives have been found or no OS

Provisioned a XenApp 6.5 Server as a golden image wiyh Citrix Provisioning Services 6.1, was getting the following error. when trying to PXE boot off the vDisk after the initial image creation.

“No bootable drives have been found or no OS”

Found that because the golden 2008 R2 Image had the 100mb System Reserved Partition which contains the boot files The Vdisk image wouldn’t bring across the 100mb partition.  and therefore couldn’t boot. So I removed the partition and recreated the Vdisk to fix the problem. below is how you delete the partition.

Here is how to delete the partition:

1) Open a command prompt with administrator privileges (right click => run as administrator)


bcdboot c:windows /s c:

You should get a message similar to:

Boot files successfully created.

2) 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”

3) Reboot to confirm that everything is ok.

4) In Disk Management you can now delete the 100Mb System Reserved partition by right clicking on it and selecting “Delete volume”
