Fresh install - USB boots to Grub prompt only

English Install/Boot/Login

Morning all

Fancied a return to Tumbleweed after some time away

I downloaded an image (openSUSE-Tumbleweed-DVD-x86_64-Snapshot20220503-Media.iso) and used UnetBootin to copy it to the USB

I have a Windows dual boot laptop with UEFI

When I enter the boot options menu, I have 2 USB options (one with UEFI)

When I try that one, it just moves to a Grub command prompt

When I try the other option, nothing happens I just get a blank screen

Could there be a corruption somewhere and should I download again?

Grateful for your advice

Cheers

I don’t know anything about that UnetBootin, but you should make a byte for byte copy of the image to the device. On Unix/Linux, I use dd for that.

I assume that is a boot menu from your BIOS. When you have an UEFI system, you should boot the installation medium also in UEFI. The openSUSE installer will then during install also use UEFI.

This I do not understand. When you boot the installer, you should not get Grub, but a menu from the installer.

I assume that you did the checksum of the downloaded ISO file. When that is OK, there is no need to download again.

Hey many thanks for quick reply, much appreciated

Unfortunately, I do not get far enough to do checksum or anything else

The fact it goes straight to a grub prompt suggests to me something is missing

This is Unetbootin:

I think I will try again with a fresh stick…

The checksum should be done on the ISO file after download on the system where you did the download. That is, of course, before you even write it to a device (DVD, or USB memory).

When on the Download page https://get.opensuse.org/leap/15.3/#download, you see the several Download versions. I assume you downloaded Offline Image. There is the Download button and it has a menu arrow at right. Clicking on it reveals, amongst others, the Checksum item. Use it to download the checksum file.

On the same page, the last paragraph tells you to Verify Your Download Before Use.

Again, when that checksum is OK, the download went OK. So whatever happens later, there is no need to download again.

Also that page links to several pages that explain how you can create DVDs and bootable USB sticks from the ISO file. I do not know what OS you use for that, but I see UnetBootin nowhere mentioned. And the description of UnetBootin says something about creating a bootable device. As the openSUSE ISO file is already a bootable image, every change to make it bootable will probably break it. As explained in my earlier post use something** that does not change anything**. For me from Linux that is dd. Also shown in the page linked to by “How to create a bootable USB stick on Linux.” (https://en.opensuse.org/SDB:Live_USB_stick) as

dd if=/path/to/downloaded.iso of=/dev/sd<X> bs=4M

(and please check and re-check that you use the correct letter for <X>, you might overwrite the wrong device!)

Perfect I’m in!
Thank you!!
