ESXi : Clone Windows 2008 R2
I ran into some issue recently when cloning an existing Windows 2008 R2 system, when manually using sysprep or using VMware to customise it I eventually ended up with the clone failing to boot with a C0000021C BSOD error.
The get around this I performed the following steps:
- Power off Source
- Change Windows 2008 R2 source type to Windows 2008 64-bit
- Clone VM
- Change source back to Windows 2008 R2 and power on
- Power on Clone allow to run sysprep
- Shutdown Clone
- Change clone to Windows 2008 R2
Don’t ask me why it works, it just does….
