disk unbootable after changing options

[scoolplace]

Hello,
pve-manager/5.4-15/d0ec33c6 (running kernel: 4.15.18-27-pve)

So, i tried to change scsi controller type from lsi53c895a to virtio scsi single and i have activated the ssd emulation option.

After stop->start disk became unbootable.

I booted via systemrescuecd , and it says that disk is unpartitioned and unformatted.

did i do it in the wrong way?

Proxmox VE 5 is end of life.

Could you post qm config <vmid>?

Note that "Stop" (in constrast to shutdown) is akin to pulling the power plug of a running computer and may damage the VM data.
