I am new to Ubuntu. I have erased windows and installed Ubuntu 20.04. But after installation I am not able to boot. In BIOS I can see Ubuntu option but when I click nothing happens. I am using ASUS F571 - UEFI system with GPT disk partitions. I have tried to repair GRUB from Live Ubuntu USB disk but nothing happens. Can somebody please help.

    There is no Ubuntu 20. There is a 20.04 and a 20.10 – David Apr 18 '21 at 12:10

    What happens exactly when you try booting Ubuntu? – ChanganAuto Apr 18 '21 at 12:17
  • be patient it will work ... every hardware setup is different ... during ubuntu install it probes hardware and tries its best to adapt its settings though sometimes it needs some hand holding ... https://help.ubuntu.com/community/Boot-Repair is the tool of choice ... boot into liveUSB and get online to install it ... post the URL it gives you on finishing so others can lend a hand – Scott Stensland Apr 18 '21 at 12:17

    @David It is Ubuntu 20.04 – Darshil Apr 18 '21 at 12:20
  • "nothing happens" is too vague. It's likely that something happens: A flicker, a change of screen, a beep, disk activity, fan speed change. If GRUB fails to acknowledge any keypress at all, check that your keyboard is properly connected. – user535733 Apr 18 '21 at 12:20
  • Ubuntu 20? There is no such release. Ubuntu uses yy.mm format (year.month of release) for all server & desktop releases, the yy being used only for IoT and specialist appliance/device releases (also suitable for cloud use) that can use snap packages only. By Ubuntu 20 you imply Ubuntu Core 20, a different product to Ubuntu 20.04 LTS, so please correct your question. – guiverc Apr 18 '21 at 12:21
  • @ChanganAuto Asus BIOS utility page stays as it is – Darshil Apr 18 '21 at 12:26
  • @ScottStensland Yes I understand, I have tried Boot-Repair tool and also tried to update grub. I have followed all the methods in link. Now the problem is I don't have neither windows nor ubuntu running on my system. I'll post the URL I get from boot-repair – Darshil Apr 18 '21 at 12:26

    UEFI settings > Boot... Make sure "Ubuntu" is selected. That should be all. Your Boot Repair info clearly states the boot order as the USB flash (because you're booting from it) followed by Windows (the now non-existing OS that still has .efi files in the ESP). – ChanganAuto Apr 18 '21 at 14:50
  • @ChanganAuto In boot priority Ubuntu is there link but when I open Boot menu, it is empty link. I have attached images in the link. – Darshil Apr 19 '21 at 04:08

I was facing the same issue. While installing instead of selecting "Something else", I selected "Erase everything" and that worked for me.
