After rebooting my Ubuntu VM I can no longer boot up. I have no backups or recovery service vault.

I can't access GRUB, I can't use sudo commands in the cloud shell terminal. ALAR gives me an OS type error. I am completely stuck.

    @Delger Myagmarjav

    Please follow the guide here: Troubleshoot a Linux VM by attaching the OS disk to a recovery VM using the Azure portal

    Per the error message I would first check fstab to make sure that you are using the blkid to mount instead of device name.

    Hope this helps. Let me know if you run into any issues while troubleshooting and I will do my best to assist.
