Hi,
the installer of Proxmox VE is independent of Debian. Is this by any chance a SD card/eMMC flash you are trying to install on? Proxmox VE installer does not support installations on such disks.

Please switch to a terminal by typing CTL+ALT+F2 and post the output of ls -la /dev/disk/by-id.
 
inside in my pc is installed ssd disk.

Could you take a look at ls -la /sys/block

I meant a device exposed as mmcblk device, see https://forum.proxmox.com/threads/unable-to-get-device-for-partition-1-on-device-dev-mmcblk0.42348/. But never mind, that is not the issue here. Please follow the command suggested by @fschauer and also post the output of udevadm info /dev/sda

Edit: Also, not that it is not recommended to run Proxmox VE of an USB stick, as they will wear out and fail.

And there you have the reason why the disk is not detected: ID_FS_TYPE=iso9660, the proxmox installer ignores disk with this filesystem type, in order to avoid interfering with the installer medium. So wipe the disk and the installer should be able to see it.
i guess, this will be enough?

Yes, it should suffice to wipe the first couple sectors of the disk.
