All Volumes are Simple Volumes

Hi.

Recently I had an idea of installing clean W10 and then Ubuntu with GRUB to dual boot them.

The thing is I have all things back-upped on the outer hard drive and I don't need anything to remain. So what I intended to do was booting W10 installation and just delete all partitions, making one for System and for Windows then divide it for some additional logical drive for additional data after installation and rest of space leave unallocated for Ubuntu.

Today I first time saw that all my volumes are Simple volumes...
HP_RECOVERY, HP_TOOLS, New Volume (D:), SYSTEM, Windows (C:)

So my question is that if I can delete these volumes during W10 installation like normal partitions or not?
If not, what I am supposed to do?

I don't need HP_Recovery, HP_Tools. I wanted to create clean system.

Welcome to the forum the simple thing is to delete all partitions don't create new let windows create what it needs you can shrink them later if needed. I prefer to run any other o/s with virtual box as a virtual machine a lot less problems

Welcome.

Thanks for the answer but the thing is if I will be able to delete them via W10 installer? Will it see these volumes?

From what I read it is better to leave some unallocated space for linux than shrinking some space from already existing partition.

First off all, I would create the Factory recover disks before deleting the HP_Recovery, HP_Tools.
I have Win and Lubuntu on a single SSD and my data is on a HDD.
Beware: You are going to delete all partitions
- Boot Win 10 64 (on UEFI mode if your BIOS is UEFI), go to install, custom, advanced, delete all partitions, create a new one leaving space for Ubuntu (~40G) (Win will create the needed partitions) and proceed.
For example, if your disk is 500G, when creating new partition after deleting all, make this new ~450 G so Ubuntu will have the remaining 50 G

As far as I know I have legacy BIOS.

I was thinking about making lets say 400GB windows extended partition, then extend it on 50/350GB on system&important software/data&not important software and Linux ~100GB (30 for root, 10 for swap coz I hibernate/sleep a lot and 60 for home)

Backing to HP partitions... I think recovery one is corrupted coz I don't see recovery option from boot menu (should be under F11) and second thing I don't have discs so only USB is an option.
But I won't recovery to win7 from factary recovery. What I want to do is setting everything up and making recovery point on Win10 (I don't know if recovery while using dualbot won't override GRUB ^^)

I would make the Win 7 recovery disks (Or USB disk). I's always another option. And if one day you want to sell or give the computer, it has more value if it's able to have Win 7 and / or Win 10.
As I wrote previously, just boot Win 10 64 (on UEFI mode if your BIOS is UEFI), go to install, custom, advanced, delete all partitions, create a new one leaving space for Ubuntu (~50G) (Win will create the needed partitions) and proceed.
At this point win 10 will create the recovery partition on the space you set for Win 10, leaving the remaining as RAW (unformatted).
After installing and configuring win 10, boot with the Ubuntu installation disk and install it on the RAW partition. I normally reserve a space for swap close to the size of my ram.
