+Step-by-Step Instructions
+📀 1. Clone the OS to the New SSD
+
+We’ll start by cloning your OS from /dev/nvme0 to the new SSD (/dev/nvme1).
+a) Partition and Format the New SSD
+
+First, partition the new SSD (/dev/nvme1) and create the root partition:
+
+# Launch fdisk to partition the new SSD
+sudo fdisk /dev/nvme1
+
+    Type g to create a GPT partition table (if it's not already).
+
+    Type n to create a new partition, use the entire disk.
+
+    Type w to write the partition table.
+
+Then, format the new partition (/dev/nvme1p1):
+
+sudo mkfs.ext4 /dev/nvme1p1
+
+b) Mount the New SSD
+
+Create a mount point and mount the new SSD:
+
+sudo mkdir /mnt/ssd
+sudo mount /dev/nvme1p1 /mnt/ssd
+
+c) Clone the OS from /dev/nvme0 to /dev/nvme1
+
+Now, we’ll copy the entire root filesystem, excluding /home, to the new SSD:
+
+sudo rsync -aAXv / --exclude=/home --exclude=/proc --exclude=/sys \
+--exclude=/dev --exclude=/run --exclude=/mnt --exclude=/tmp \
+/mnt/ssd/
+###################################################################################################
+This command copies the entire OS and system data but excludes /home, as we’ll sync that separately later.
+🧩 2. Prepare the New SSD to Boot
+a) Mount Necessary Filesystems and Chroot
+
+To make the new installation bootable, we need to bind mount critical filesystems and chroot into the new root.
+
+for dir in dev proc sys; do
+sudo mount --bind /$dir /mnt/ssd/$dir
+done
+
+If you are using UEFI, you might also need to mount the EFI partition:
+
+sudo mount /dev/nvme0p1 /mnt/ssd/boot/efi  # Adjust if needed
+
+Now, enter the chroot environment:
+
+sudo chroot /mnt/ssd
+
+b) Update /etc/fstab
+
+Make sure /etc/fstab points to the correct root filesystem and removes any /home partition references.
+
+blkid  # Get the UUID of /dev/nvme1p1
+nano /etc/fstab
+
+Ensure the / entry is updated to use the new SSD, for example:
+
+UUID=<new-uuid>  /  ext4  defaults  0 1
+
+And remove or comment out any /home partition entry.
+c) Install GRUB on the New SSD
+
+Now install GRUB to make the system bootable from /dev/nvme1.
+
+grub-install /dev/nvme1
+update-grub
+exit
+
+🔄 3. Reboot from the New SSD
+
+    Reboot the system.
+
+    Go into BIOS/UEFI and set /dev/nvme1 as the primary boot drive.
+
+    Boot into the new SSD.
+
+📁 4. Sync /home from /dev/sda (Old Home Drive)
+
+Now, we’ll sync the /home data from the old drive (/dev/sda) onto the new root partition.
+a) Mount the Old /home Drive
+
+First, mount /dev/sda (the old /home drive):
+
+sudo mount /dev/sda1 /mnt/oldhome
+
+b) Sync /home to the New SSD
+
+Now, copy the /home data:
+
+sudo rsync -aAXv /mnt/oldhome/ /home/
+
+Make sure /home is mounted correctly on /dev/nvme1p1 (the new SSD) by checking with df -h or lsblk.
+🧹 5. Cleanup (Optional)
+
+Once you verify everything works as expected:
+
+    Remove /home entry from /etc/fstab if it exists.
+
+    You can either repurpose or wipe the old drives (/dev/nvme0 and /dev/sda).
+
+    Confirm everything is working fine and you’re now booting from /dev/nvme1.
+
+✅ Final Checks
+
+    Check disk usage:
+
+df -h
+
+    Verify partitioning:
+
+lsblk
+
+    Verify boot order in BIOS/UEFI to make sure you're booting from /dev/nvme1.
+
+This approach ensures you move everything safely, with minimal risk of data loss.
