DATA LOSS!!

Hi,
I made a big mistake.
I tried VMWare vSphere Hypervisor (ESXi) I downloaded it and installed it in a bootable USB drive.
I bought a new hard drive to test it.
I created the USB drive in another hard drive a CentOS 7 system where I have a lot of work and projects.
I was in a rush and I forgot to change the cables of the hard drives when I started to install and I installed the VMWare vSphere Hypervisor (ESXi) where I had the CentOS 7 system with my work.
I just installed the VMWare vSphere Hypervisor (ESXi) I didn't do anything else.
I have old backups but I will loss important data if I don't recover it.
Could you recommend me the best way to recover the data.?
Or even better recover the partitions that I had before the wrong the installation?
If there is away to recover the partitions probably i will not lose almost anything because the system it was empty only the fresh installation installation.
Thank you.
Regards

By default. ESXi tries to use the entire disk, but even it you tell it not to...
ESXi rebuilds a new (MSDOS type) partition table, and re-formats the disk during install.

Once this happens, you pretty much need a professional data recovery. $$$$
Even then they will likely only recover whatever wasn't over-written by the install.

G'day @jvr968 and welcome to linux.org :)

Christophe Grenier's TestDisk might do the trick, it features on products such as Rescatux, SuperGrub2 etc.

Mostly Debian-based, but there is a version downloadable for CentOS.

Have a read of

https://www.cgsecurity.org/wiki/TestDisk

https://www.ubuntupit.com/top-15-linux-data-recovery-tools-the-professionals-choice/

https://www.supergrubdisk.org/tag/centos/

or just Google

testdisk centos

and see how you go.

I have had success with it before, but a couple of years ago now, and you might need to go to something like "Deep Search" within it, which will take some time.

Good luck

Hello @jvr968 !!!

There are some good tools out there that, may help you such as PhotoRec or Testdisk but usually is difficult to recover everything and in order.
