Boot device not found (HP Omen 880-138no) and I can't reinstall with the Windows Media Creation Tool

[Ebbenezer]

Hi, Im having a problem with my desktop "HP Omen 880-138no".

Yesterday I was going to reinstall Windows 10 64-bit on the Omen. Everything to my knowledge worked fine, havent had any issues. I started the Windows recovery program from settings and started the prosses. It told me after a few second that it had failed and gave no futhure information. Since it didnt work I found out that there was a HP Recovery program built into the pc recovery menu, so I clicked on that to start the recovery as there is a "RECOVERY" perition on the pc on about 15gbs. That one failed too. I got the error screen "HP Recovery Manager failed. Errorcode = 0xEFFFFF23". The computer restarted and I got the boot device not found screen:

"Boot Device Not Found"

"Please install an operating system on your hard disk"

"Hard Disk - (3F0)"

Even though I am a novice at computers, I didn't panic, because I know the files are still there and can be recovered.

But I had yet another issue I can't seem to understand.

I had a USB flash drive ready with the Windows Media Creation Tool in case something happend. I changed the boot order so that the USB would load first. It loaded fine and the program started. However, neither the "Repair computer" or "Install now" features worked. The "Startup repair" told me that it couldn't repair the computer and the "Install now" featuer told e that there isn't a partition with windows installed on the drive.

Everything to my knowledge is there, I was able to check the files and it seems in order, its just that it fails to boot and fails to reinstall Windows. I don't have any of the discs that came with the PC as i bought it used. I dont have a system image either unfortunally, so Im hoping there is somthing I can do with CMD to fix the boot, or anyhting else of course.

I'll be happy to awnser any questions you might have. Thanks for your time and I'll be looking forward to your response.

According to the specs for this model, it came with a 128GB SSD and a 1TB HDD.  I would open the case and remove the HDD before you do anything else.

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.

Since that tool starts out by reformatting the drive, even if there is something on the SSD, that should not present a problem with the reset.

Good Luck
