I installed Win2008 service beginning with 1 Hard Disk which is a SATA disk, I simulated it as SCSI disk. Later on I attached a new physical disk to my machine and created a new datastore in my ESXI. In virtual machine settings, I added a new hard drive to my existing Win2008 as IDE HD. But somehow the IDE harddisk is always disk 1 and my existing disk (SCSI) becomes disk 2, no matter how I add/remove disks, and I am unable to boot my Win2008 from my SCSI disk. Everything works if I remove the new IDE disk.
Anybody has idea how can I configure the boot sequence of adjust disk sequence of multiple disks?
Is there a reason you are using IDE. I would just make the drive scsi.
If you need to change boot order you can change BIOS settings. Reboot the machine and make changes in the BIOS.
