How to Manually Boot CloudLinux 8.10 from GRUB Shell Print

When your CloudLinux 8.10 server fails to boot and drops into the GRUB shell, follow this step-by-step guide to manually boot the system.

Step 1: Access the GRUB Shell

If your server is stuck at the GRUB rescue or command prompt, you will see a screen similar to this:

At this point, you need to manually specify the root partition and load the Linux kernel.

Step 2: Identify Available Disks and Partitions

First, list the available disks and partitions:

You will see output similar to:

Each (hd0,gptX) represents a partition on the disk.

Step 3: Find the Root Partition

Check the contents of each partition to find where your root filesystem (/) is located:

If you see directories like:

This means (hd0,gpt3) is your root partition.

Step 4: Find the Boot Partition

Since /boot is on a separate partition, check (hd0,gpt2):

If you see kernel files such as:

Then (hd0,gpt2) is your boot partition.

Step 5: Manually Boot the Server

Now, execute the following commands:

1. Set the Root Partition

2. Load the Linux Kernel

Explanation:

• (hd0,gpt2)/vmlinuz-4.18.0-553.34.1.lve.el8.x86_64 → The kernel file in the /boot partition.
• root=UUID=e9bc4ed0-0f48-4433-9a3a-5f7d56243a0c → Specifies the root partition.
• ro → Mounts the root filesystem as read-only for initial boot.

3. Load the Initramfs

4. Boot the System
