Issue/Bug Description: I'm running Pop!_Os 19.10 and have not any problem. Today I wanted to install 20.04 with a fresh install. I've flashed pop-os_20.04_amd64_nvidia_5.iso to my USB drive with Pop!_Os's USB Flasher app. But the problem is I can't boot it with UEFI, I'm only able to boot it with Legacy Boot option. There was no problem with installing Pop!_Os 19.10 with UEFI.

When I try to boot 20.04 with UEFI (sorry for the blurry photo),

this screen comes

after that, it reboots my system and boots my already installed Pop!_Os 19.10.

Steps to reproduce (if you know):

1. Download Pop!_Os 20.04 Nvidia version from the website
2. Make a bootable USB disk
3. Boot it with UEFI

Expected behavior: It should boot like it was on 19.10 with UEFI.

Other Notes: I've tried with USB Flasher, Balena Etcher, Rufus and dd from the command line.

Also, there is no problem with the legacy boot. I'm able to boot it with the legacy boot.

Same issue - for what it is worth it looks like the original post is a Dell, and I am also a Dell XPS 9380. Boots to GRUB, then you make your selection, and screen goes blank and sits there. Doesn't appear to matter how the disk is made.

Yeah, I'm using dell inspiron 7567.

Iam same issue, i'm using acer nitro5 515-52

I using dell inspiron 5567 and having the same issue but i work around it by create a boot option mapping to /efi/boot/grubx64.efi and it boot just fine don't really know why

[cansozbir]

@Slotheacientone Can you share steps you take or a link about that?

[cansozbir]

I did solve my problem by creating a boot option too. There is a file named grubx64.efi under the /efi/boot/ of your installation disk. And you should pick this file from Add Boot Option here.

Laptop: Dell Inspiron 15-3551 Running OS: Windows 10 (not activated) Required OS: Pop_os 20.04 Flash Drive: SanDisk Cruzer Blade 16gb

Same issue here, but I tried only with UEFI and not legacy boot(I'm kinda new to this so kinda scared to try that out). I flashed my usb with balenoEtcher and Rufus multiple times and tried booting it, but all ended in vain, and followed the same pattern.

As in this original post, when I boot it, I get that 'Pop_os' logo thing on my screen along with the timer for boot. But after few times, I noticed a single line message at the bottom of the screen(that was why I didn't realise it the first time), it read "Boot OS not found". And that was why I changed from balenoEtcher to Rufus, but still the same message.

The sequence goes like: 1)I press F12, to go to boot options. 2)There I select my SanDisk usb under UEFI. 3)A complete black screen with a message of "Boot OS not found". This lasts for only a second. 4)Pop_os logo with a timer for booting on its own(the pic which the original poster had) 5)Then a series of lines (codes or something, as if it's running something) over a black screen. And this too lasts for a couple is seconds. 6)Finally the silence from my laptop, nothing seems to be on,the screen is black, keys don't seem to work, and power button too didn't. This freaked me out at the beginning, but I pressed the power button for some 10 secs or so, then after 1 or 2 sec, I pressed it again, normally, and came the familiar booting, which booted the Windows 10 OS.

This occurs everytime, and I badly want to use Linux (especially pop os, seems attractive to me). I couldn't find a solution across the web.

So anyone please help me with this. I wish to complete change the os, not any double boot stuff(my pc won't be able to handle it).

@VoidSkull24 Did you try that? https://github.com/pop-os/pop/issues/951#issuecomment-622983199 As you can see I'm also using UEFI instead of the Legacy boot option. You can create a boot option for your flash drive like I did and try booting your installation media from that option. I'm not sure is it the same issue that happened to me.

@cansozbir Thanks a lot for the response. I simply couldn't understand what you did....(cuz I'm practically a newbie with these things)And GRUB.., it's something in ubunto right, I'm using Windows rn. And also, the windows explorer is not detecting the bootable usb, which I think is common, so I can't edit that efi file there as per that comment.

Actually, you should do that from your bios, not from your Os, so it's not something related to Linux or Windows. Write iso to the USB you have. Reboot your computer. After pressing f12, do NOT select your USB to boot, there should be an option to go to the bios settings. And after that, find your boot sequence options from your menu. You should see windows from there, and there should be something like "add boot option" like mine. After pressing it, it will pop-out something like file explorer I guess, and you should select the file named grubx64.efi under the /efi/boot/, but you should start with your USB device. Like your_usb_device/efi/boot/grubx64.efi. Then you're all set! Do not remove your USB drive, save your bios settings and reboot your computer, then press f12 again to select the booting option, and do NOT select your USB device, just select the booting option you created from your bios, I can't remember that if you write a name for this booting option, if so, select it, if not, you can just recognize it I think because it was not there before :) I hope that helps :)

Please be careful and do not delete your windows' boot option from there

@cansozbir Thanks a lot, I will try it out and will be careful while doing it. ^^
