Restore Kubuntu on a hosed system

us flag

My Dell Inspiron 16 is totally hosed. This machine has peculiar bootup behavior in any case, since there's no way to simply boot from a CD or memory stick that doesn't depend on the installed operating system. In its current state the system gives me a Grub prompt no matter how I start it. I can then boot from USB or a CD (it says). I have both Windows and Ubuntu installed (but now inaccessible) as a result of some misadventures with Boot Repair. I also have various systems on memory sticks, but none of them will start either Ubuntu or Windows. I do have a memory stick with SuperGrub which enables me to access various images but none of them work.

I suppose that what would get me going would be a memory stick that will boot Windows (unlikely) or some form of Linux. But almost everything I try takes me back to that Grub prompt or that devilish Windows boot-repair loop. If I could find a Linux system that would start up, that could be way in. Even then I would have a long road to a working system, probably via a Dell factory image restore. I also have SuperGrub, which will take me to the installed systems, but not to a starting point that works.

Any hints or suggestions? I do have an HP laptop running Kubuntu and Windows, but it's infuriatingly slow.

You can try booting it from the grub prompt using this procedure https://www.linux.com/training-tutorials/how-rescue-non-booting-grub-2-linux/ if your pc is uefi the last part - to fix it - won't work, but if it's bootable this should boot it.

Seems like we need to know more about the "*peculiar bootup behavior*." Is this some kind of security you built? Or it is a set of BIOS settings you chose? Or is this some kind of Super Duper Secure Boot run amok? Or is this something baked into the BIOS that you cannot disable? (If so, how did you install Ubuntu?)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
