There was one partition that GParted could not read it said it was a 'Microsoft system partition' of type 'unknown.' I created an NTFS partition of the exact same size instead, and then later used dd to copy the 'unknown' partition from the HDD to the SDD. I set up the SSD to be a GPT volume, and then I recreated each partition from the HDD to the SSD, down to the exact size and sector. Inside the SystemRescueCD window environment (which you can get to by typing startx) I ran GParted, which scanned all disks connected to the system. WARNING: if you accidentally boot from your sysprepped disk, it will proceed to install. I also connected the factory 1 TB HDD (still sysprepped, never-been-booted), and the new 256GB SSD I planned to migrate the installation to - both of these drives via SATA cables to the motherboard. I rigged up a system that I booted from my USB SystemRescueCD flash drive (if you don't know how to do that, you shouldn't be trying this). What didn't work: using dd to try to copy a partial disk or a partial partition, or the boot sector code. (I wanted to stick with GPT/UEFI booting.) The version of GParted I used had the ability to create GPT bootable volumes, as well as the older, traditional MBR type boot records. System Rescue CD contains GParted, which I found to be totally adequate for what I needed to do. (Tried it on two different computers.) However, System Rescue CD (on CD or USB) has never failed me. But before doing ntfsclone it is necessary to have a duplicate partition table of the HDD on the SSD.DISCLAIMER: Why would you take a drive out of a never-been-booted, brand new computer and mess with it? You could totally mess up your drive and your Windows installation for your brand new computer! Proceed at your own risk! You should be fairly familiar and comfortable working with and setting up disk partitions.Ĭlonezilla: I could not find a boot image that would work from a USB flash drive. Then I started looking for NTFS cloning tools – turns out ntfs-3g has a utility called ntfsclone which does exactly that – it copies just the data, not complete blocks. ddrescue was showing estimated time as 17 hours!!! That too when the total data in the HDD is around 200 GB combined – OS (C drive) and Data (D drive). But copying 1 TB from a HDD which reads at max 100 MB/s to a SSD which can write at almost 1500 MB/s is surely an extremely slow job. So the first try was using a block to block copy, using ddrescue. Also you may need to adjust the commands to suit your system to select the correct drive and/or partition when copying partitions. If you are following this post, read it completely before attempting anything. ![]() You usually don’t need to install any extra packages, etc. To those who don’t know, SystemRescueCD is a kind of Swiss knife Linux distribution you can use to do all kinds of disk and OS recovery tasks. As someone who has done something of that sort many times, but with Linux based OSes my first thought was if I could do some sort of stuff with a SystemRescueCD running from a USB pen drive – as I wasn’t willing to use any Windows based backup solution since I had no idea how they work, or whether they work at all. So, I had an interesting problem at hand – to transfer a completely working Windows 10 installation from a 1 TB HDD to a 1 TB NVME SSD (Samsung 970 EVO Plus).
