Hi there,
I went through this problem:
On my notebook I have Endless OS only, I tried to install Lubuntu deleting all partitions. Unfortunately I was not able to boot the new OS. I have sen somewhere that before launching the install of Lubuntu I should open a terminal and launch some commands in order to “prepare” the partitions but don’t remember where…
Any help, please ?
We are very sorry to hear that Endless OS did not fulfill your needs, unfortunately, the installation of other OS which is not Endless OS is out of our hands
Hi, I am not asking help in installing another OS. I am, asking how to aboid boot problems after removing Endless OS. I have read in your community that in case of SO change, the partition setted by Endless OS will make your pc unbootable, like efi problems or something like that.
What are your issues with EOS? You know that you can run a complete Ubuntu installation inside EOS, so you get the best of both worlds: The outstanding stability and user interface of EOS and the flexibility of Ubuntu.
In case you want Lubuntu, run sudo sgdisk --zap-all /dev/sda with the Lubuntu Live Media to completely wipe your internal hard drive. Make sure that /dev/sda is the correct drive by running sudo blkid.
If you’ve already uninstalled Endless OS then it is already beyond the scope of the Endless OS support we can offer here. Although I would indeed expect your PC to effectively stop booting when you remove the OS, I know of no specific reason that the previous existence of an Endless installation would prevent you from installing another OS on an ordinary PC. Feel free to post the link to the information you are referring to.
Along the lines of egrath’s suggestion, we’d also be interested in any feedback you have on Endless & how it could be improved to meet your needs.
Hi, I did not uninstall EOS, my questions rise from a previous problem (2 weeks ago):
After an update I wasn’t able to boot into EOS, so i thought I could fix it installing another linux distribution (I am quite familiar with Ubuntu and derivatives) but after the installation process the error was still there.
Then I tried installing Win10 first and then booting in Win and download and install EOS. This worked.
But just after fixing everything I saw a post (witch I mentioned in my first post) explaining that before installing correctly another SO deleting EOS you must wipe the partition table or something similar.
Just curiosity.
Thanks for the extra info. Endless just uses normal partition tables so I don’t think there’s anything different about replacing Endless compared to replacing any other OS.
Glad to hear you have it working now via the dual boot path. Do you happen to recall exactly which error you were seeing after the upgrade?
Hello Daniel, the error was a prompt on a black screen, right after turning it on (terminal style)
The message was the following:
error no such device ostree
Edit: this message wasn’t shown only once but it was like un a loop. So it was prompted every secondo.
The problem is a combination of various things
/EFI/BOOT/BOOTX64.EFI
So, if for some reason the installer failes to set the correct boot entry in NVRAM, you end up booting with the default bootloader, which got installed by EOS. Hardcoded in this Bootloader (which is GRUB UEFI), is the root partition which holds your installation, but is no longer available, as it got overwritten by the other installation.
Essentially, if you want to switch operating systems and have a single-boot configuration, wipe your entire disk so that the installer doesn’t get confused.
