iMac 2019 running Fusion 11.5.6 on macOS Catalina. Windows Server 2012 vm that had been working just fine for a long time. VM lives on a Drobo Mini RAID attached via USB-A.
Was removing some not often used software from Windows…I recall the titles being FileZilla and Parallels Tools. (Yes, this VM had been migrated from VMware to Parallels and back to VMware over the years.) The Parallels Tools removal asked for a reboot, not unexpectedly. Rebooted the VM and…BSOD with ‘INACCESSIBLE_BOOT_DEVICE’ error.
I can boot Windows Server 2012 into Repair Mode. But none of the reduced function boot modes work – Safe, Safe with Networking, etc. – all fail to boot.
The only thing I’m able to do is boot to the Command Line. diskpart shows all of the volumes, partitions, etc. that I’d expect. chkdsk /f completes successfully. But I can’t seem to force re-recognition of the boot disk.
I’ve tried creating a new VM, using the existing virtual disk from the original VM. No success there.
I am able to mount the virtual disk in another VM. Again, the disk appears to be ok – chkdsk, Disk Management > defragmentation – both complete successfully. The partition map appears to be viable. But, still can’t boot the VM to which the virtual disk belongs.
I realize I’m not the first person to encounter this…’INACCESSIBLE_BOOT_DEVICE’ is discussed all over Microsoft forums / KBs, VMware forums / KBs, etc. I’m just hoping to scare up some suggestions for things to try to resurrect this VM. Thanks very much.
