Problem about error Os, when installed openSUSE

Hello everybody.

I have installed openSUSE tumbleweed on my computer but when I reboot my computer take out the USB stick and reboot again my bootloader says that there is no operating system installed on my computer. My computer is a laptop from HP.

When I put that USB stick and start my computer it start normally.

I have installed Linux Mint before on this computer and faced the same problem but I didn’t know how but I got rid of it. But now again I am facing this problem.

Can you guys give me a solution for this?

Thanks in advance…

Looks like you have not installed he bootloader (GRUB2) to your HD drive, maybe you installed it inadvertently to the USB drive.
Or you changed the disk priority in BIOS before installing and didn’t reset: try rebooting, press F9 during POST and select the HD to boot and see what happens.
By the way, do you have more than one HDD connected?
