[SOLVED] Problems migrating a Win10 Hyper-V machine - Hangs on boot

[randal.junior]

Hi folks,
First of all sorry about my bad English, it's not my primary language.

I'm trying had to make a migration from a Windows 10 on a Hyper-V VM to Proxmox, but having serious troubles.

My VM was originated on a BIOS based machine, and unfortunately I can't reinstall the OS, couse of legacy reasons. But on the Hyper-V it's working perfectly.

I followed this steps:
1 - Opened the Hyper-V VM executed sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to make sure every thing is ok;
2 - Installed VirtIO Drivers with \virtio-win-gt-x64.msi and \virtio-win-guest-tools.exe;
3 - Exported the Hyper-V VM to get the .vhdx disk image;
4 - Copped the image to a usbdrive.

On Proxmox:
1 - Created a VM with the following parameters, and imported the image qm importdisk 106 SERVIDOR.VHDX bigdisk_fast;

root@giotto:~# qm config 106
balloon: 0
boot:
cores: 6
cpu: host
machine: pc-i440fx-9.0
memory: 8192
meta: creation-qemu=9.0.2,ctime=1733490962
name: Win-CL-ERP
net0: virtio=BC:24:11:22:1F:21,bridge=vmbr0,firewall=1
numa: 0
ostype: win10
scsihw: virtio-scsi-pci
smbios1: uuid=33019ddc-73d4-401b-a74d-2497b0c38802
sockets: 1
unused0: bigdisk_fast:vm-106-disk-0
vmgenid: 30469968-90cf-4399-913e-c22a5e8020b9

2 - Attached the harddrive in IDE0/SATA0/SCSI0 (all with same result);
3 - Attached a Windows ISO and VirtIO ISO;
4 - Booted from the CD image, get to windows rescue, and command prompt;
5 - Installed the drivers on the windows via dism /image:d:\ /add-driver /driver:h:\vioscsi\w10\amd64\vioscsi.inf, also installed \viostor\w10\amd64\viostor.inf and\viomem\w10\amd64\viomem.inf;

Finally I booted for the first time, but it loads the windows logo and hangs. Just stay on this screen, with no memory consumption and a single core at 100%.



If I stop the VM and restart I can get to the Repairing screen, and with a F8, I can acesses safe mode with network.



I don't see any hardware or driver that could be causing the windows not to load at standard mode.



I'm stuck here for a few days and any advice would be great.
I already tried to exclude and reinstall the drivers that are warnings but have no luck.

Have good news.

It seen to be a Nvidia driver problem.

In safe mode a was able to run the Display Driver Uninstaller DDU from https://www.guru3d.com/download/display-driver-uninstaller-download/ and bcdedit /set hypervisorlaunchtype off;

Then used msconfig to disable any graphic driver:



Now it booted into Windows 10, been able to reinstall all virtio drivers.

Came back to default initialization, just keep the base video, cause I don't want to use the windows GUI nevertheless.

Hope I can help anyone.
