Legacy to UEFI restoration fails with system restart without error

Thread needs solution

Hello everyone. I'm trying to restore a backup taken from legacy to UEFI. My system is a server Dell poweredge 330 with a Perc H730 RAID controller running MS windows server 2016. The system as, I've found it, was running on Legacy/MBR configuration, with RAID 5, on 4 SAS, 1TB disks. I've taken the backup using Acronis Cyber Backup on an external usb drive. Now I'm using 4 SAS, 4 TB disks and want to setup a RAID 10, UEFI installation. As a first step I've setup RAID 10 and recovered the backup into Legacy/MBR, using a MBR boot media, on the new disks and worked really fine. Yesterday I've tried the same, but this time I've turned the boot settings into UEFI and I've used a GPT boot media. Acronis have started just fine and I thought that it will be again a piece of cake. Unfortunately, although everything seemed to be fine and the program was telling me that the restoration process will convert the installation into UEFI automatically, when I've started the procedure the server restarted and boot again into the acronis restoration console. I've tried once more but again the same behavior. (I've selected the whole disk restoration option, which automatically is checking and the MBR tick box). Then I've entered into the controller management console and deleted and then recreate the virtual disk. I've repeated the restoration procedure and added the verify backup, restored data and the restart option. The restoration has started and until 10% everything was great. I've left the office late last night and though that in the morning everything would be fine. Today I've found the server with an error, no boot media found. Rebooting into the acronis console there were no history logs and into the local machine drives I was able to see the whole directory tree structure. I've turned the boot setting into Legacy and the server started into windows server normally. The really weird thing was that the os instance wasn't the one of the backup (12.02.2019), but yesterday's (12.09.2019) instance right before the restoration procedure has started!!!!! I don't really know what in the earth have happened but I would appreciate any ideas you may have. Best regards Nick

Reading all day long instructions and posts, I think I'm going to reinitialize the disks and retry.

Hello Nikos,

welcome to Acronis forums!

I suggest that you created Acronis WinPE bootable media and try restoring into UEFI with it.

In order to investigate the weird restore behavior that you reported, please reproduce this issue, make screenshots/photos of the restoration procedure steps, your screen after reboot and error message. Please also collect Acronis System Information from Acronis Bootable Media after problem reproducing but before reboot.
