Windows 10: I deleted a partition from windows 11 that had linux installed and now I am stuck in GNU...

Hello, So, I have a Windows HP Envy 15. From a curious mind and very new to OS, I decided to install Linux Ubuntu via the dual boot route and partition my HD. Recently, that allotted space ran out so I booted into windows and deleted it and also extended that space back into the main C drive. Once I restarted my computer, it took me to the GNU minimal terminal and I cannot escape it. I tried the following command: --chainloader hd0,gpt1/efi/microsoft/boot/bootmgfw.efibut when I do that, it says it cannot find the grub file so, I am assuming I must of deleted the files to the grub menu.Any ti

:)

 

Windows 11 not rebooting after uninstalling Linux mint in dual boot mode. Removed the Linux partition before uninstalling Grub. Screen showing GNU GRUB version 2.06 on the screen.

Windows 10 Installer deletes linux partition

I have a Ubuntu and windows dual-boot and while upgrading to widows 10 during one of the restarts grub wouldn't boot a partition and went into recovery so I used a Ubuntu live CD and GParted informed
me that my linux partition was missing. It was listed as un-allocated. This means that the Windows 10 installer deleted that partition. (The helpdesk told me to post it here)

 

GNU GRUB interference with my Windows 11 installation

I use Linux, and my bootmanager of choice is GNU GRUB, but the issue with that is, I want to install Windows 11 as a separate partition to which to dualboot into for stuff like; video games that do not run on Wine due to anticheat false alarms that are a big thing on Linux and testing C.S projects on Windows.

And I have an 8GB flash drive with the latest Windows ISO flashed onto it, and as I try to boot into the installation, it doesn't! But Instead it gives me the plain GNU GRUB screen I do not wish to see when doing this.

It doesn't display anything, just the default GRUB screen.

I really need to get Windows working asap, and I've never met an issue like this before although I've been using Linux for 3 years, and did not find a specific guide for my issue so I'm here to ask for help.
