Migration from ESXİ to Proxmox?

[starmen]

I’m new to virtualization and migration processes. Right now, I’m trying to learn Proxmox, and while learning, I’ve come across many different problems and errors.
Currently, I’m dealing with the Proxmox ESXi import wizard. When I tried to migrate my Ubuntu machine from ESXi to Proxmox, I clicked the Import button and waited for the import/download to complete.
After the download finished, I tried to start the machine, but I keep seeing the same issue over and over again: “Not a bootable disk”
How can I fix this problem?

was the original vm also installed with bios?
otherwise you can try to change the bios type to uefi

First, double-check your VM’s hardware settings: in the Proxmox GUI under your VM’s Hardware tab, make sure your converted disk is attached to the primary controller (e.g. VirtIO-SCSI0 or IDE0, depending on how Ubuntu was installed) and that it’s listed first in the VM’s Boot Order. If you imported into a SCSI device but left the VM in BIOS (SeaBIOS) mode while your Ubuntu install was EFI, switch the VM to OVMF (UEFI) under Options → BIOS, or vice versa.
