To shrink C: partition from Windows, first open a Command Prompt window and execute the diskmgmt.msc to open Windows Disk Management utility which will be used to Shrink the volume (assuming that windows is installed at the beginning of the disk on the second partition, after the System Reserved partition and has C: letter assigned) in order to reduce its size to minimal. ![]() System Reserved + Recovery + EFI partition + Windows C: partitions must be smaller or equal than the total size of the SSD reported by a utility such as fdisk.ġ. The calculations for this step are simple: MBR Partition Layout from Disk Management Check MBR Partition Layout GPT Partition Layout from Disk Management Check MBR Partition Layout Step 1: Shrink C: Partition of Windows Systemīe aware that in the case your windows C: partition from the HDD is larger than the total size of your SSD you will need reduce its size to fit on the SSD. On the below screenshots you can review the initial Windows partitioning scheme in case of a MBR layout style and GPT partition layout performed from UEFI. In this case Fdisk command line utility should report the disklabel type as GPT. If disk in partitioned in MBR layout from UEFI, you should clone all partitions, such as Windows RE partition, EFI System partition, Microsoft Reserved partition and Microsoft basic data partition which holds the Windows OS partition, typically the C: drive.

This guide assumes that both disks (old HDD and SSD) are physically plugged-in into your machine simultaneously and Windows OS is installed on a disk with MBR partition scheme table. You can download the iso and burn to a CD.This tutorial represents a practical excerpt on how to migrate (also known as cloning) a Windows 10 Operating System from a large HDD with multiple partitions, such as C:, D:, to a smaller SSD using a Linux distribution which includes Clonezilla utility.Ĭlonezilla utility can run from PartedMagic Linux distribution CD ISO image or directly from Clonezilla Linux distribution CD ISO image. So I had to go back and do the “mkinitrd” step before it would boot.Īs tsu2 suggested, it is probably easier to use clonezilla. The reinstall of booting was misleading, because yast says that it is creating “initrd”. yast bootloader to reinstall booting and switch from grub2-efi to grub2Īctually, first reboot failed.The rest needs to be done in rescue mode.Remove “/etc/crypttab” (won’t be needed).Remove the line for mounting “/boot/efi”. Mount the corresponding partitions (the planned “/” and “/home”) at “/mnt”.Now use the same external USB drive, and boot that on the destination virtual machine. I used “dar” for the backup, but other backup software could also work. Make a backup to a partition on that external drive (I have a large partition for that).Mount at “/mnt” (or similar suitable place). I did not mount the EFI partition, since I did not need that. Mount the partitions that I wanted to clone. ![]() Using that linux from the external drive: I plugged in a USB external drive, where I had linux installed. Original – UEFI booting, using an encrypted LVM.ĭestination - Legacy BIOS booting, and no encryption. This was from one virtual machine to another. I just did something similar, but with Leap 15.0. Is its a easy way to clone 30 GB disk to 120 GB SSD disk partion without to reinstall everything?
