After restore no driver SCSI Controller

[geraldstefan]

Hallo,

I had an old server 2012 and I made a backup, then I restored the image to the new server but I received (INACCESSIBLE_BOOT_DEVICE) because the disk drivers from SCSI Controller) wasn't installed after restored.

Example Veeam from boot rescue-CD after restore:

SCSI-Controller Install drivers......
SCSI-Controller Install drivers......
Microsoft-Controller Online
ATA Channel 1 Online
Red Hat VirtIO Ethernet Adapter Online


What can I do in order to make the server start and see the driver/hard disk?


Thank you very much for your help
Gerald

Hi Gerald,

Was the recovery media made on that server?

English translation and technical improvement:

I encountered a similar issue while attempting to restore a Windows Server 2012 R2 VM from VMWare to Hyper-V 2022. After completing the restoration, the VM would not proceed past the boot process, displaying the error: inaccessible boot device.

Here are the steps I followed to successfully restore the VM.

1) Preferably, remove VMware Tools from the VM before restoration.

2) Convert GPT disk to MBR
For more information, visit: https://4sysops.com/archives/how-to-p2v ... -gpt-disk/

3) Delete initial partitions, except for the recovery partition.

4) Boot with the Windows Server 2012 R2 CD and activate the operating system partition:
> diskpart
diskpart
list disk
select disk 0
list partition
select partition 1
active
exit
<shutdown>

5) Boot with the Windows Server 2012 R2 CD to repair boot files:
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
<shutdown>

6) Boot with the Windows Server 2012 R2 CD and repair the BCD:

Using the same steps explained in Solution 1, enter the command prompt and type the following commands, pressing Enter after each one.

a) To boot from partition C: System
bcdboot c:\Windows /l en-us /s c: /f ALL

b) To boot from partition E: Recovery:
bcdboot e:\Windows /l en-us /s e: /f ALL

c) If booting fails, repair as follows:
‘cd / X: \ EFI \ Microsoft \’ where 'X:' is the drive letter of the boot partition
‘bootrec /fixboot’
‘ren BCD BCD.bak’

7) Create a Generation 1 machine in Microsoft Hyper-V 2022, with the BIOS option to boot via IDE.
Add the disk as an IDE Controller.
