Windows 10: How to consume Unallocated space on HD

Yes, I can boot from my old drive (which disk 3 now). Are you asking that in case something goes wrong with my disk 0?

 

Do you mean merge all these partitions:



Also I can only merge two partitions at a time. Is that how I do it?

 

Exactly. If something goes wrong inadvertently - there can anytime be many a slip between the cup and the lip *Biggrin -, you can then reclone your original system drive.

If we decide to go through the method 3 of the referenced article Top Three Methods for Moving Unallocated Space to C Drive in Windows 10 using AOMEI Partition Assistant, I would like you remove Disk 1 ,Disk 2 and Disk 3 and keep them aside safely and have only the Disk 0 which we will be manipulating. I would also recommend that you copy any personal data on Disk 0 which you may not want to lose to another media before such manipulation.

I would still wait for some more time for other experts' opinion.

Note: I would insist again that you take full screenshots whether it is WDM, Partition Wizard or AOMEI Partition Assistant.

 

A lot depend upon if you ever want to possibly restore the factory software load or not. If you never want to restore the factory software load, then recovery partitions are completely optional. You can do everything by booting from a recovery or installation USB flash drive that you can do with the recovery partition, except for restoring the factory software load.

If you will never want to restore the factory software, then delete every partition to the right of C: drive, then expand C: drive to fill the newly created empty space.

 

Yes, I extended my C dive over all partitions on the right. Restarted the computer and everything seems to be working. Can I do the same to the partitions on the left side of the C drive?

 

Leave them alone, needed for booting and UEFI.

 

Great!, thanks for all the help provided.
