Help with installing bug
 

Hi, I'm new with linux and I had Ubuntu 16,04 dual boot with Windows 10. I tried installing gnome shell, but I didn't like the integration, so I decided to uninstall and replace with Ubuntu-Gnome. Just after I finished the process, there's this huge popup window saying the installation failed and there's was a problem with grub and after rebooting a black window "Minimal bash-like editing is supported. For the fist tab....Then I installed again and the same error...A decided to erase ubuntu partitions from Windows and reinstall again (now with Unity) and just the same happened (I used the same bootpendrive that successfully installed for the first time, so I don't think thats the issue).
I'm brazilian and I tried all the foruns solutions in portugese (Run the Live Cd [?????] with root user [no idea how to do it], mount the partitions [?????]). So I just returned to Windows 10 after removing Linux Again but I want to use linux.

if you reestablished Windows BOOT and MBR repair and are now just booting into Windows by Windows own boot loader.
I'd wipe that USB Stick, then redo it with a Distro I want to install. then just try it again. Using the how to install a dual boot install methodology.

Because the MBR was repaired by Windows placing the MBR back to the state it was in before that issue developed.

maybe even download a new iso of whatever it is you want to install then using that one instead.

maybe this is a UEFI problem...

Yeah, could be the UEFI GRUB boot was not properly installed on the EFI partition when the Ubuntu GNOME was installed.

Let's try install the Ubuntu GNOME:

- First re-make the USB stick for Ubuntu GNOME
- Boot into USB stick
- Make sure you know which partitions are for Windows and which one is EFI
- Mount the EFI partition and delete any grub/ubuntu boot loader already found there
- Unmount EFI partition
- Create partitions for Ubuntu GNOME (basically for / and swap)
- Install:
- Be careful not to erase everything and install Ubuntu, because there's an option for that
- Choose "Something else", then choose your partitions you created above
- Be sure to choose the EFI partition for installing the boot loader
- proceed with installation ...

By then you should have a working Ubuntu with GRUB as boot loader on the EFI partition.

However, if GRUB is not shown at boot, then restart and get into the BIOS, and change the boot orders.
If there is no GRUB in the boot managers found in the BIOS list, please let us know and we'll help further.

All the best.

I followed fellow BW-userx's tip, but the same error occurred. So I decided to delete all of Ubuntu files and restore Windows. I really believe the problem is what you said, but how to proceed since I deleted Ubuntu?

It's ok. Now you know you have a clean environment to work with. You can try a clean install from a newly made USB stick following the steps above.

Check this out for making bootable USB in Windows:

Just make sure the EFI partition does not contain GRUB from the old Ubuntu install. This might break everything again.

well like that guy said right after me @ondoho that I decided not to comment on, because he brought up a good point. that should have been a red flag to look into it first. so I left it alone. because I stated MBR (only)

EFI which I do not deal with. I stick to mbr installs. my BIOS was written when that was first starting out, so all it has in it is an experimental mode for EFI, and I choose not to experiment with it using that BIOS that does not have full control of EFI.

therefore if you have EFI Windows then yes you can mbr Linux from what i know but that makes life a little more complext, it'd be easier if one is dual booting Windows and Linux to do some of it windows way, in other words, if Windows is booting EFI then intall Linux the same way.

Most main stream Linux/GNU's now create their iso's to install either way, and self detect if the BIOS is UEFI or MBR'ing, so it should pick up on it when booting the USB Stick that has it burned to it, but do not quote me on that.

I've only did an install of UEFI once and it was on someone else Laptop "shooting in the dark" when I did it. and It turned out fine, though I could have redone it to make it so he did not have to hit a button on the keyboard to select it - I think, he did not give me enough time to play with it.
Install and run is what he did on me.

nevertheless, as I do not deal with EFI on a daily basis it is not in my, not at all actually, it is not stored in my personal QRAM (my brain)for quick retrieval.


anyways, it cannot be that hard or difficult as UEFI has been out long enough if one has the proper hardware and matching software UEFI Bios and UEFI software. installing it cannot be any harder then installing an MBR boot system.

because I accomplished it without even knowing what I was doing before hand. (disclaimer:I know not everyone's brains work the exactly the same way due to ..... (left out to not make this into a some kind of medical post,) though types of brains can be categorized. )

just read the prompts and follow them. keeping in mind if you mess it up it is not the end of the world, just try it again.

this requires having back-ups of both OSes if needed, and the time to do it just in case one may have to re-install both Windows and Linux.

that may take time as well, as I took the time to get that "new" Install Windows (10) off a USB Stick figure it out by doing it, then getting it onto a different (sdd) hdd then adding Linux.

repetition helps build confidence

so if you mess it up the first time, do not go into oh crap mode too hard, or for too long. Just take what you learned from that and try it again. eventually it will work as long as one is not repeating the very same steps that made it fail.

if the hardware is not dead, then formatting and starting over is always an option. Kind of, like life.

Thanks for your time to answer me, I really appreciated! It was really an EFI but, apparently. I was able to install without problems now.
