Effect of Changing Partition Sizes

Thread needs solution

Acronis True Image 2019
Windows 10 Pro
My single physical disc is GPT, Windows 10 boot UEFI

I have a full disc backup of one physical drive which has my C boot partition.

If I move or resize any partitions on my one physical drive, does that change data in the Track 0 & MBR, EFI System partition, or Recovery partition?

Thank you for the feedback.

John, provided you use a partition manager application to make any changes to the size or location of your partitions, then this should update any related information for the partitions in the table where this is stored.  You should not move or resize the hidden/system partitions, and should take care if touching recovery partitions.

I tend to use the free MiniTool Partition Wizard for this type of operation, but please ensure that you have a good full disk backup as a precaution before making any changes.

I had a similar issue on a Dell XPS Win 10 UEFI system -- C drive plus 3 hidden partitions (winRE and Dell recovery partitions.  I was trying to migrate from a .5 TB SSD to a 1 TB SSD. and to expand the C: partition to use all of the 1TB SSD drive except what was needed for the EFI boot sector and the hidden restore drives. I used Boot Media to do a full disk backup but discovered I couldn't alter the partitions sizes on restore, unless I wanted to make them smaller  (The Acronis User Guide is a little misleading on this point). Since all of the unallocated space on the 1TB, after restore, was after the last hidden partition, I couldn't extend my 'C drive' system partition in Disk Manager (only works if the unallocated space is right next to the partition you're trying to extend). Win 10 Disk Manager wasn't helpful here.  You can only create a simple volume (e.g. 'D:' drive) from the unallocated disk space.

Solution:  Do a full-disk backup of the .5TB SSD drive to an external . Swap in the 1TB SSD drive. Run a full restore to this drive. Verify the new disk will boot. Start up Disk Manager and note the size (in MB) of each of the partitions, and the size of the unallocated space. Calculate by how many MB you can expand the C: partition and still have enough room for the hidden partitions. Next run a backup (from the 1TB SSD drive) using the Boot Media. But this time, only back up the hidden partitions. Remove boot media an boot to the regular Windows 10 system.  Bring up Disk Manager and delete the 3 hidden partitions (the ones that follow after the C: partition). Expand the C: partition (by the amount you calculated earlier).  Next shut down and boot from the Acronis Boot Media.  Restore the 3 hidden partitions, and for the destionation for each of them, point to 'Unallocated Space' on the target drive.  After the restore is complete, detach the Acronis Boot Media and boot to the Windows 10 OS.  If all looks correct, boot from the Acronis Boot Media and run a full disk backup to the external HD. You now have a fully-utilized new SSD and a current backup image for recovery.
