Please help with Ubuntu GRUB killed by Windows on dual boot (I hate Windows 🤬)
Hello!
[This is my post from Reddit, where I did not receive much help.]
This might get a bit emotional, but I really hate Windows! It's only installed on my computer for occasionally playing Civilization, Rust, or DayZ. However, even that doesn't stop it from wasting my time and nerves to the maximum.
So, the characters in this story: me, my computer, Ubuntu, Windows, ChatGPT 4, ChatGPT 3.5.
Background: Since I've encountered Windows not playing nice with other OSes on the same machine before, I knew that I needed to install Windows first, then Ubuntu, to have the option to choose the OS at boot. I have 2 M.2 SSDs. I installed Windows on the first one, then Ubuntu on the second one. Everything worked perfectly. But it turned out my knowledge of Windows' treachery was not complete. One fine day, after successfully finishing a game of Civilization with a victory, I decided to shut down the computer, and of course, Windows couldn't resist the opportunity to update itself. Everything went fine. But the next day, when I wanted to boot into Ubuntu to work, it turned out that Windows, even after updating, killed the bootloader. I was furious. I thought that by correctly installing the systems, I had freed myself from these worries. It was naive.
I lack the knowledge to quickly fix the bootloader. I turned to the internet, read several articles, and tried to copy-paste commands, but quickly concluded that the general scheme wouldn't work for me. I decided to turn to AI. On the first day, things seemed to be going well; I booted from the Ubuntu Live USB, copy-pasted chat commands, and provided the output for control. Everything seemed to finish without errors, but upon rebooting, nothing had changed. I saw "Reboot and Select proper Boot Device or insert boot media in selected boot device and press a key" again.
I decided to try again the next day. Today, with renewed vigor and hope, I embarked on the battle. Again, I carefully executed chat commands, everything was going fine until I hit the request limit for ChatGPT 4. I had to switch to 3.5, and it turned the process into a nightmare. It stopped checking errors properly and gave scattered ideas. It all ended with suggesting creating an additional partition for the bootloader, and objections like "it used to work fine without it" didn't bother it.
In the end, I realized that I can't handle it without community help. And for these two days, I simply don't have the nerves, considering that I wasted two days just because Windows doesn't play nice with other OSes. And this is coming from someone who has been behind a computer for 20 years. What about newcomers?
I ask for help with my problem. Here's how I described it to the chat:
I am in BIOS. I have these options. Boot mode select: LEGACY + UEFY. Boot option #1: Hard Disk: Samsung SSD 970 EVO Plus 1TB (this is my Ubuntu). Boot Options #2: Windows Boot Manager (Samsung SSD 970 EVO Plus 1TB) - this is a separate SSD with Windows. I installed them in this order: 1. Windows, 2. Ubuntu (which created a menu where I can select which OS to boot). But after Windows update, it broke my menu. After I did all above, I still have this error while loading from Ubuntu SSD: Reboot and Select proper Boot Device or insert boot media in selected boot device and press a key.
Thank you to everyone who managed to read to the end!
What has been done:
Used Boot Repair with no luck.
Step 1: Verify Disk Partitioning and Boot Configuration
Step 2: Determine Boot Mode
Step 3: Check GRUB Configuration and Bootloader Installation
Actually I forgot I can share chat URL, You can see prompts and terminal outputs there:
