Clone Ubuntu and Windows to new SSD

Question

I want to switch to SSD from HDD. I have dual boot on my hp laptop. My C drive in Windows and Ubuntu / directories have less size than new SSD.

But the whole HDD is of 1 TB and SSD of 240 GB. I am putting my SSD inside laptop using hard disk candy into the CD/DVD slot. And I'm not planning to use the DVD port for DVD again.

How can I clone both systems (only C drive + Ubuntu /) without reinstalling everything if that's possible? I want to use SSD for the operating systems and the old HDD for storage. Noob here. Thanks in advance.

Answer 1

• Connect both HDD and SSD to the PC.

• (optional) Boot Windows installation, install drivers for SSD, shutdown.

• Boot PC from live cd/usb (Ubuntu will be ok).

• Open gparted. Resize all partitions to smallest possible size, but leave around 100 mb of free space on each one. And move partitions closer to "left border". Apply this operation.

• Open terminal. Detect which drive is your HDD and which one is SSD (see cat /proc/partitions)

• sudo dd if=HDD_DEVICE bs=1M of=SSD_DEVICE - it will take some time

  (for example: sudo dd if=/dev/sda bs=1M of=/dev/nvme0n1)

• sudo partprobe SSD_DEVICE (for example: /dev/nvme0n1)

• Probably, you'll need to expand partition table and file systems again, so you can use gparted again.

• Shutdown. Remove HDD.

• Try to boot again.

Next:

• If everything looks ok, you can connect HDD, format it, and use as you wish.
• OR Change UUIDs of HDD file systems: tune2fs /dev/sda1 -U random /dev/sda1 (probably the same for sdb if you have, etc). But don't do this with your SSD!

This operation is potentially dangerous. Be attentive with device names you're using!
