I was using Ubuntu 16.04 but I have encountered WiFi issues from the first day. So I wanted to switch to Linux mint.To backup my data I want to create another partition and install os in the home one,for that I have gone to Gparted and tried creating a partition,but failed. So copied all my data to external drives and made Linux mint bootable USB by using Ubuntu default bootable software. I have restarted my pc and gone to bootmenu and that's it ,I'm struct there, first error is
PXE E61:Media test failure. Connect cable
PXE M0F: Exiting PXE Rom then I can go to bootmenu,so gone to it but I can't install Linux mint. After doing whatever solution I have seen in YouTube I have installed Linux mint somehow. Installation is complete and the system asked to remove usb stick nd restart I have done it. But then I'm struct at bootmenu. I need help urgently, I'm about to face my campus recruitment,so I need my pc very badly now, please let me know a solution as soon as possible. https://1drv.ms/f/s!Avw5iGizu2U2dcrr4wXfVbsqcOE

If sounds as if the computer is trying to boot from the network.

The first thing I would do is check the BIOS of the computer. When you boot, do you see something like "Press [some key] to enter setup"? If so, press that key to enter setup and check the boot settings. Let us know what you find out.

What is the make/model of the computer?

Yeah.. I have got it. It's working. I entered into setup and chooses "load default legacy os". And my pc booted cool and working properly. Thank you so much frankbell.

Congrats! Glad I could help.
