I have tried to install Ubuntu OS from USB stick but failed. All installation process going well and at the end it shows to restart laptop after installation and when I click to restart laptop, it shows: "Operating System not found".
I have used several USB stickes, I have used "Rufus 3.6" and "Universal-USB-Installer-1.9.8.8" to make bootable USB stick, I have tried to install Ubuntu and Linux Mint but the result is always the same: "Operating System not found". Please, help. I need it for my semester exams :(

Laptop: Fujitsu Siemens Amilo Si 2636
Processor: Intel (R) Core (TM) 2 Duo CPU T7500 @2.20 GHz

I attached all the pictures of Boot Setup: https://rashidov.wordpress.com/2019/09/06/bios/

Important Note: Boot Device Priority does show Hard Drive. It shows only USB stick when I insert USB stick into laptop.

Maybe this information will help you. So I insert the USB stick to the laptop (it contains Linux Mint for installing) and switched on Laptop and it booted automatically from USB and I entered to Linux Mint and then I checked information about Hard Driver in the section called "Disks":


Model: WDC WD2500BEVS-22UST0 (01.01A01)
Size: 250 GB
Partitioning: Master Boot Record
Serial Number: WD-WXHX06073***
Volumes: Filesystem - Partition 1 - 250 GB Ext4
Size: 250 GB
Device: /dev/sda1
UUID: 94d71065-bacf--*
Partition Type: Linux (Bootable)
Contents: Ext4 (version 1.0) - Not Mounted
 
When I enter to BIOS in Boot section "Boot Device Priority" does not show Hard Driver. It shows only USB stick whenever I insert USB to the laptop. When USB stick in the laptop "Boot Device Priority" shows : USB Hard Disk.
and that is all. Please check the 5th photo on this link:

The 5th photo does not show the Boot Device Priority highlighted (only the "LAN Boot"). What do you see when Boot Device Priority is highlighted?
Unfortunately, it is not possible to highlight "Boot Device Priority". When I go the section "Boot". It is only written:

LAN Boot : [Disabled]

Boot Device Priority





That is all. Nothing else written there. :(

You can not hit the down arrow of your keyboard to select Boot Device Priority?
No, I cannot. Because Boot Device Priority shows nothing. If I insert USB stick to the laptop then " Boot Device Priority" shows "USB Hard Disk".
But in other cases, it shows totally nothing. That is why I cannot highlight Boot Device Priority.

Are you very familiar with Linux? Have you installed Linux on a computer before?
I do not think so I make a mistake in the installation process. Cause it seems easy. Installation process goes quite well but at the end it show "Operating system not found". I have installed only Windows 7 several times but not Linux.

When installing, do not manually change the partitions, instead try the option of removing completely any other OS and use all the available disk space for Ubuntu or Mint or whatever.

Thanks to all who tried to help me.
I have tried everything but the result was the same and in the end I decided to buy a new HDD and the problem solved. Additionally, I bought SATA USB cable and now I am using my old HDD as an external Hard Drive.

Thanks to everyone.
