I am trying to install new Ubuntu version 18.04.3 on my window 7. After i have made a setup in USB its running fine on USB but when i try to install it on my system after successful installation and restart it still asks for Ubuntu installation option and when i remove USB it is not working properly. I have used 'something else' option and made new partitions so no old data or Windows on the PC left. Any suggestions please?
Thanks for the replies. It’s working fine now so far. What I was doing wrong was not selecting HDD as the first option after restarting the system. I had to make the Hard Drive option as the first one instead of USB Drive.
