Troubleshooting Bootloader and Storage Issues After Dual Boot Setup in Linux Mint: A Comprehensive Guide

Welcome to a detailed exploration of the challenges encountered when configuring a dual-boot system with Linux Mint and Windows 10, specifically focusing on bootloader complications, storage capacity discrepancies, and intermittent boot failures. We’ll delve into the intricacies of your setup, providing solutions and insights to help you regain control of your system and optimize your workflow.

Understanding the Problem: A Breakdown of Your System’s Issues

Your situation presents several intertwined issues stemming from your migration to Linux Mint, the subsequent dual-boot attempt with Windows 10, and the complexities of NVMe storage management. Let’s dissect each problem individually:

Problem 1: Boot Menu Instability and Drive Duplication

The erratic boot menu behavior, characterized by inconsistent order and duplicated drive entries, is a classic symptom of a bootloader conflict. When multiple operating systems are installed, especially on different drives, the bootloader (typically GRUB in Linux Mint) struggles to accurately identify and manage boot entries. Windows’ influence on the bootloaders of both NVMe drives exacerbates this issue. Removing the 1TB drive temporarily mitigates the problem, but it’s not a sustainable solution.

Problem 2: Persistent 1TB Storage Limitation After Cloning

The failure to expand the cloned 4TB NVMe drive to its full capacity, despite using gparted, indicates a potential issue with partition tables and/or the way the cloning process was executed. Incorrect partition alignment or residual remnants from the original 1TB drive’s partition table can prevent the drive’s full capacity from being recognized.

Problem 3: Intermittent Boot Failures and ACPI/I2C Errors

The most concerning problem is the inconsistent boot behavior, manifested by the Mint logo freeze, emergency mode activation, and the appearance of ACPI and I2C errors. These errors suggest hardware or driver-related issues. The “i2c i2c-1: Failed to register i2c client ITE8853:00 at 0x40” error often points to problems with I2C devices, while the “ACPI Error: Aborting method _SB.PC00.PEG1.PEGP._DSM due to previous error (AE_ALREADY_EXISTS)” error is related to the Advanced Configuration and Power Interface (ACPI) configuration. Both are known to cause boot-related problems, which are frequently associated with the motherboard’s BIOS or UEFI settings.

Resolving the Issues: Step-by-Step Solutions and Strategies

To effectively address these issues, we’ll present a structured approach, focusing on re-establishing boot stability, optimizing storage, and resolving the boot failures.

Step 1: Addressing the Bootloader and Boot Menu Instability

The best strategy is to create a unified bootloader on a single drive, preferably the 4TB NVMe drive where you plan to install Linux Mint.

  1. Backup: Prior to any changes, create a comprehensive backup of all your data. This is paramount.

  2. Boot from a Live Linux Mint USB: Boot your system from a Linux Mint installation USB drive.

  3. Identify the Boot Drive: Within the Live environment, identify the correct drive (the 4TB NVMe in this instance). Open a terminal and use lsblk to list block devices. The output will show the drives and their partitions. Note the device name of your 4TB NVMe drive (e.g., /dev/nvme0n1).

  4. Reinstall GRUB: Use the following command in the terminal to reinstall GRUB on the 4TB NVMe drive. Replace /dev/nvme0n1 with the correct device name (e.g., for a GPT partitioned disk):

    sudo mount /dev/nvme0n1p1 /mnt  # Assuming /dev/nvme0n1p1 is your /boot/efi partition (usually an ESP)
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
grub-install /dev/nvme0n1
update-grub
exit
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt/sys
sudo umount /mnt
    • This process installs GRUB to the master boot record (MBR) or GUID Partition Table (GPT) of the specified drive, ensuring it becomes the primary bootloader. The /boot/efi partition must be mounted before grub-install for the GRUB to work.

  5. Verify Boot Order in BIOS/UEFI: Access your BIOS/UEFI settings (usually by pressing Del, F2, F12, or another key during startup). Ensure that your 4TB NVMe drive is the primary boot device. Disable legacy boot if it’s enabled, as UEFI is generally preferred for NVMe drives.

  6. Test the Boot Sequence: Reboot your system and verify that the boot menu is consistent and accurate, with the correct entries for your operating systems.

Step 2: Correcting the 4TB Drive Partition and Capacity

To utilize the full 4TB capacity of your drive, follow these steps:

  1. Backup: Ensure all essential data is backed up.
  2. Boot from Live USB: Boot into your Linux Mint Live environment, as you did in Step 1.
  3. Launch GParted: Open GParted (a partition editor) from within the Live environment.
  4. Select the 4TB Drive: In GParted, select the 4TB NVMe drive from the device selection drop-down.
  5. Delete and Recreate Partitions: Delete all existing partitions on the 4TB drive. After deletion, create a new partition table; in most modern systems, choose GPT (GUID Partition Table) to support the full 4TB capacity.
  6. Create Partitions: Create a new partition for your Linux Mint installation. Ensure the partition is formatted with the desired file system (e.g., ext4). Create an EFI System Partition (ESP) of around 512MB formatted as FAT32. This partition is crucial for UEFI-based bootloaders.
  7. Apply the Changes: Click the “Apply” button in GParted to implement the partition changes.
  8. Reinstall Linux Mint: Proceed to reinstall Linux Mint onto the freshly partitioned 4TB drive. During the installation process, the installer should automatically detect the available partitions and configure the bootloader (GRUB) appropriately.
  9. Verify Capacity: After installation, boot into your new Linux Mint installation. Verify that the file manager or df -h command in the terminal displays the full 4TB capacity of your drive.

Step 3: Troubleshooting and Resolving Boot Failures (ACPI/I2C Errors)

The intermittent boot failures require more in-depth investigation. Begin with these steps:

  1. Update BIOS/UEFI: Ensure your motherboard’s BIOS/UEFI firmware is up to date. Visit the ASUS website and download the latest version for your specific motherboard model. Follow the manufacturer’s instructions to update the BIOS. Newer BIOS updates often include fixes for ACPI and hardware compatibility issues.

  2. Investigate ACPI Errors: The ACPI errors suggest a problem with how your operating system interacts with your hardware. In the Grub boot menu, select “Advanced options for Linux Mint”, select a recovery mode, and boot into it. Then run the following command:

    journalctl -b -p 3

    This command will display any recent error messages. Examine them carefully, focusing on ACPI-related errors, and research the specific error messages online for potential solutions. Common ACPI issues may be resolved by adjusting settings within the BIOS/UEFI.

  3. Check for I2C Device Compatibility Issues: If the “i2c i2c-1: Failed to register i2c client ITE8853:00 at 0x40” error persists, it indicates a conflict or problem with an I2C device. These devices often control hardware like sensors or display interfaces.

    • Investigate the ITE8853: Research the ITE8853 component to identify its function within your system. It could be related to your display or other hardware.
    • Update System Drivers: Make sure your system’s drivers are up to date. Update drivers for the motherboard, video card, and any other hardware components, and also, search for updated kernel drivers for any hardware components to improve compatibility and resolve potential conflicts.
    • BIOS Settings: Explore BIOS/UEFI settings related to I2C or SMBus (System Management Bus, which often uses the I2C protocol). Try disabling or enabling related options, testing each change. Sometimes, disabling I2C devices in the BIOS can resolve boot errors.

  4. Kernel Parameters: In the Grub boot menu, edit the boot command by pressing “e” on the keyboard. Add these parameters, one at a time and testing between reboots, to see if they provide any improvement. The following are some options you could try:

    • acpi=off: Disables ACPI entirely (use as a last resort, as it may limit power management features).
    • noapic: Disables the Advanced Programmable Interrupt Controller (APIC).
    • pci=nomsi: Disable Message Signaled Interrupts (MSI) for PCI devices.
    • iommu=soft: Enables the software IOMMU.
    • quiet: Suppresses boot messages.
    • splash: Displays the splash screen.

  5. Check System Logs: If the errors continue, examine the system logs for more detailed information. Use the journalctl command to view system logs.

    journalctl -b  # Show logs from the current boot
journalctl -b -1  # Show logs from the previous boot

    Look for errors, warnings, and any clues that may point to the source of the problem.

  6. Hardware Troubleshooting: If software solutions fail, consider these hardware-related steps:

    • Reseat Components: Unplug the computer, unplug the power cord and then reseat essential components like the graphics card, RAM modules, and NVMe drives. Ensure all connections are secure.
    • Test RAM: Run a memory test to check for RAM errors. Many systems have a built-in memory test in the BIOS/UEFI, or you can use a bootable memory testing tool like Memtest86+.
    • Check for Overclocking Issues: If you’ve overclocked any components, revert to stock settings. Overclocking can cause instability, especially during the boot process.
    • Component Isolation: If possible, disconnect non-essential hardware components (e.g., extra USB devices, sound cards) one by one, to see if they are causing a conflict.

Step 4: Planning and Implementing Your Dual Boot Strategy

Once the core issues are resolved, you can proceed with reinstalling Windows 10 in a VM and configuring the dual boot setup. Here are the recommendations:

  1. Choose a Virtualization Platform: Select a virtualization platform like VirtualBox, VMware, or KVM/QEMU. KVM/QEMU, when configured with a graphical frontend like virt-manager, often provides the best performance.

  2. Install Windows 10 in a VM: Install Windows 10 within the virtual machine. Allocate a reasonable amount of resources (CPU cores, RAM, and disk space) to the VM.

  3. Configure Virtual Machine Settings: Configure the VM’s settings according to your needs. For example:

    • Network: Configure network settings (e.g., bridged networking) to allow the VM to access your network.
    • USB Passthrough: If you need to access USB devices from Windows, configure USB passthrough.
    • Shared Folders: Set up shared folders between the host (Linux Mint) and the guest (Windows 10) to easily transfer files.

  4. Test Windows 10 VM: Test the Windows 10 VM to ensure it functions correctly.

  5. Configure a Dual Boot for Convenience (Optional): If you prefer, you can set up a dual boot configuration for your Windows VM directly from your Linux Mint installation.

    • Using GRUB: You can add an entry in GRUB to boot directly into your Windows 10 VM. This is a more advanced option, requiring specific configuration.
    • Using a VM Manager: Most virtual machine managers, such as virt-manager and VirtualBox, offer options to create boot entries for your VMs.

Addressing Your Backup Needs: Optimal NAS Integration

Timeshift’s inability to utilize your NAS is a limitation. You need a backup solution that can leverage your 16TB of NAS space. Here is our recommended backup approach:

Option 1: rsync with a Custom Script

  • Benefits: Highly flexible, versatile, robust, and ideal for advanced users. Provides full control over backup processes.

  • How it works: rsync is a command-line utility for efficient file transfer and synchronization. You can create a custom script to:

    1. Define source and destination: Specify the directories you want to back up on your Linux Mint system and the NAS directory as the destination.
    2. Exclude unnecessary files: Include the option to exclude temporary files, cache files, and other files you don’t need to back up.
    3. Utilize SSH: If your NAS supports SSH, use it for secure data transfer to your NAS.
    4. Implement compression: Employ data compression for faster backups and reduced storage space.
    5. Automate using cron: Set up a cron job to automatically run your script at regular intervals (e.g., daily, weekly).

  • Example script (basic):

    #!/bin/bash
# Define source and destination
SOURCE="/home/your_username"
DESTINATION="your_nas_ip:/path/to/backup" # e.g., 192.168.1.100:/mnt/backup/mint_backup

# Exclude unnecessary files
EXCLUDE_LIST="/home/your_username/exclude.txt"

#Create exclude.txt
cat > $EXCLUDE_LIST << EOL
/home/your_username/.cache
/home/your_username/.local/share/Trash
/home/your_username/Downloads/*
EOL

# Run rsync
rsync -avz --delete --exclude-from="$EXCLUDE_LIST" "$SOURCE" "$DESTINATION"
    • Replace your_username, your_nas_ip, and /path/to/backup with your actual values.
    • Create a file named exclude.txt in your home directory (as indicated in the script) to specify files or folders to exclude from the backup.
    • Use sudo crontab -e to create cron jobs to run the script.

  • Advantages: Highly customizable, efficient, handles incremental backups, and can work well with NAS.

  • Disadvantages: Requires basic scripting knowledge, might be more complex to set up initially.

Option 2: BorgBackup

  • Benefits: Uses deduplication to save space, supports encryption, reliable, and efficient for large amounts of data.

  • How it works: BorgBackup is a deduplicating backup program.

    1. Install BorgBackup: Install the BorgBackup package on your Linux Mint system.
    2. Create a Repository: Create a Borg repository on your NAS. This will store your backups.
    3. Encrypt: Encrypt the repository to secure your backups.
    4. Back Up Files: Run the borg create command to back up your files to the repository.
    5. Schedule Backups: Schedule backups using cron.

  • Advantages: Efficient deduplication, encrypted backups, and works well over SSH with a NAS.

  • Disadvantages: Steeper learning curve than simple rsync.

  • Example:

    # Create a repository (replace with your information)
borg init --encryption=repokey ssh://user@your_nas_ip:/path/to/borg_repo

# Create a backup
borg create --verbose --stats --compression auto --exclude-caches /path/to/backup/files ::backup-{hostname}-{now}

# List backups
borg list ssh://user@your_nas_ip:/path/to/borg_repo

# Restore a backup
borg extract ssh://user@your_nas_ip:/path/to/borg_repo::backup-hostname-2024-10-27T10:00:00

Option 3: Duplicati

  • Benefits: GUI interface, encryption, support for a wide range of backends (including NAS), good for both simple and complex backups.
  • How it works: Duplicati is a cross-platform backup tool with a web interface.
    1. Install Duplicati: Install Duplicati on your Linux Mint system.
    2. Configure Backup: Use the web interface to create a backup job.
    3. Select Destination: Select your NAS as the backup destination.
    4. Encrypt: Enable encryption to protect your data.
    5. Schedule: Schedule the backup job.
  • Advantages: Easy to use, supports various backup locations, secure.
  • Disadvantages: Potentially higher resource usage, and can be a little slower in some situations than rsync or BorgBackup.

Optimizing Your Workflow and Future Considerations

Once your system is stable, consider these additional points:

  • Automate Backups: Regularly backup all important data. A backup is not a backup until it is tested.
  • Monitor System Logs: Regularly review system logs to catch potential issues early.
  • Keep Documentation: Keep a record of system configuration changes, BIOS settings, and backup procedures.
  • Stay Updated: Maintain a consistent update schedule for your operating system and its packages.
  • Utilize Cloud Storage: Consider cloud storage for critical data as a secondary backup.
  • Troubleshooting in the Future: If problems arise, document your troubleshooting steps meticulously. Provide detailed information to help you or others diagnose and solve similar issues in the future.
