Is there any safe way to divide the C drive?

[dim1024]

Hello everyone!

I bought an HP ENVY x360 Convert 15-ee0007ur laptop.

When I press F11, HP Recovery Manager starts up. Thats how i can recover my windows any time. It is very cool. 

I want to divide my C drive into 3 parts. But I am afraid that after division the possibility of recovery will be lost. Are my fears true? Is there a safe way to divide the C drive without loosing recovery possibility (i mean by pressing F11)?

Hello
so well done, this is the type of question that users ask themselves too late

So the recovery process may indeed stop working, or be useless because everything can be erased and reset to the original.
In fact it can depend on the configurations, but a too big risk
The best you can do, although I don't recommend partitioning the disk, will be to use a copy software (clone disk).
which can allow you to recover everything at a desired moment

While @Prométhée is correct in everything they told you, please allow me to offer an alternative.

If you repartition your drive, you negate the usage of the HP recovery tool -- that is true.

But, you can then use an alternative tool, that is available for free, and in my experience, works a lot better:

------------------------

I personally prefer to use third-party Backup solutions as they tend to be both more flexible and more reliable than any built-in solutions.

Macrium Reflect (MR) provides a FREE version that can be used to image and restore partitions or entire drives.

What I recommend is the following:
1) Download and install Macrium Reflect (MR) from here: http://www.macrium.com/reflectfree.aspx
2) Run MR and choose the option: "Create an image of the partition(s) required to backup and restore Windows" to write a full backup to an external drive or USB stick
3) Use the option to create a boot USB stick or CD

My experience is that MR, when using the High Compression option, typically can compress the saved image file to about 60% of the USED space in the OS partition. This means if you have an 80GB OS partition, and 40GB is used, MR only needs about 24GB to store the image file.

I use this all the time and it typically takes less than 15 minutes to do the image backup and about the same time or less to do a restore.

Plus, MR has the option to Add a Recovery Boot Menu entry. This allows you then to boot into WinRE, and you can then use that to do a restore -- when you can't boot into Windows!

NOW, you have the means to restore a full working system from the external drive or USB stick in only a few minutes.

============================

As to safe repartitioning, I have done that more times than I care to count because I do weekly online image backups and can't do that without repartitioning the drive in the first place.

I can recommend using MiniTool Partition Wizard to do this, which you can get from here:  https://www.partitionwizard.com/download.html
