Hey!
I’m new to Fedora (37), switching from Ubuntu.
I have a laptop (ThinkPad T430). Before the switch, I had a working dual boot with Ubuntu 22.04 and WIn10, with a customized GRUB Theme. Now Only Fedora is loading.
Linux Is my main system, I only use Windows these days for my cutting machine.
I did a great job with backing up my data, preferences, gnomes settings etc from Ubuntu. But I’m afraid I messed up during the install process.
I installed Fedora in place of Ubuntu, on the same partition.
When I start the computer, I only see the GRUB screen for 1 or 2 seconds (with no option, it only says “GRUB loading, welcome to GRUB”) then Fedora is loading.
It’s been a week and I tried to read as much info as I could to solve my problem but I don’t really understand how it works.
I didn’t remember that my device was UEFI compatible to be honest.
I try to “boot from the BIOS”, choosing a temporary startup device. I see Ubuntu, Windows Boot Manager, the disc player, the hard drive, and the PCI card. Windows Boot Manager doesn’t work, nor “Ubuntu” (this one seems normal).
I tried what this user tried but it did not work :
https://discussion.fedoraproject.org/t/repair-dual-boot-setup-with-windows/73726
It would be really cool if I’m able to repair the boot and not go through the install process again, as In the meantime, I pretty much set everything up on Fedora and I’m a bit discouraged to have to go through all of it again.
The output of $ lsblk and $ fdisk -l is down below, if it’s of any help.
$ os-prober results in no output (concerning… 
)
Thank you!
$ lsblk
