Thanks for your time and sorry both for my english and for my lack in computer skills. I have an HP PAVILION G6 notebook that works with Windows 8. Yesterday I tried to install Lubuntu 18.04 alongside Windows (dual boot) but I probably did it in the wrong way: first of all, GRUB doesn't show automatically and to reach it I have to enter the Bios Device Options with F9 and choose Notebook Hard Drive. I tried to "fix" that with Boot-Repair using the Linux Terminal but when I run the Recommended Repair the program shows this error:

"The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode."

So I found out that while Windows 8 works in UEFI mode, Lubuntu works in Legacy/Bios mode. I have no idea how to resolve this so I've decided to unistall Lubuntu but I'm not able to do that since I found disinstallation tutorials that concern only Ubuntu UEFI mode.

I know that there are a lot of topics similar to this one but I still didn't find anything that could help me. I just want to unistall Lubuntu and do the installation once again in the correct way.

  • In those question they work with ubuntu in efi mode (not legacy) or they require boot-repair (doesn't work for me because legacy/uefi conflict) – anto10 Oct 11 '18 at 8:27

    You don't need to un-install Ubuntu (in legacy mode), you just treat it as a unwanted partition & re-use it, or delete it. If delete is your option, you delete from whatever else is on your machine. UEFI leave bits behind, which is why it has extra steps. – guiverc Oct 11 '18 at 8:30
  • Ok guiverc so if I delete the ubuntu partition an I give it to windows I'm good? I'm asking this because I found guides that says to delete the partiton and THEN use a cd installation of windows and do something with the prompt. I don't need to do that, right? – anto10 Oct 11 '18 at 8:59
  • I understand you are going to install Ubuntu again, am I right? The guides you mentioned (but not linked!) probably include restoring Windows bootloader in the MBR which would be replaced again if you later installed Ubuntu again. – Melebius Oct 11 '18 at 9:51
