Wish to upgrade boot drive to SSD without reinstalling

Replacing your old boot drive with a solid state drive (SSD) is the best upgrade that you can easily manage, which will dramatically improve and speed up your computer performance. For this upgrade, you can reinstall your Windows onto SSD from scratch, but it is more of a hassle and more likely to cost more time and energy. Luckily, there is a quite easy way to make it done: you can simply copy boot drive to SSD.

Copying boot drive will transfer everything including boot partition, recovery partition, and other OS-related partitions from the current boot hard disk to the solid-state drive, so you do not need to worry about cloned SSD won’t boot.

Great freeware for copying boot drive to SSD

To transfer boot partition or drive to SSD, we highly recommend using the freeware named AOMEI Partition Assistant Standard. This free partition manager comes with “Migrate OS to SSD Wizard”, specially designed for Windows users to move boot drive (and other partitions that contains files vital for OS boot) from one disk to another. Besides, it is also able to clone the entire boot disk to another HDD or SSD drive via the “Disk Clone Wizard”.

No matter which way you finally choose to move boot drive to SSD, you can boot computer from the new drive successfully.

If you are looking to perform this operation between MBR and GPT, or GPT and GPT, you can upgrade to Professional edition.
