Product: HP PRO 450G0
Operating System: Microsoft Windows 10 (64-bit)
I format my 'E' drive with easeus partition software. After restart, initially it said ' Missing operating system'. I did system diagnostics everything is good, I mean 'Passed'. After that I was trying to install os from my pendrive and the result is same 'Missing operating system'. I've changed boot order from notebook harddisk to Usb hard drive. But no use. Everytime I did system diagnosis the results are passed. Please help me.

If it isn't booting from the flash drive maybe it isn't properly prepared. Try redoing it or using another flash drive.

Make an installation usb using the free Media Creation Tool. At least an 8gb flash drive required. Click "Download tool now"- and Run it. Select Create installation media for another PC.

Immediately after powering on start tapping the Esc key to open Start-up menu. From there tap F9 key to choose to boot from USB.

 

IF that does not offer USB hard drive as boot device- you may have to disable Secure boot/enable Legacy boot in BIOS.

Secure boot is disabled by default and I'm working on legacy, but no change. I checked both of the settings.
