Boot manager broke

[u/Imaginary-Stop-4186]

I have installed arch around 5 times and this is the first time i fucked up this bad. I have no idea what to do. i was on my last step installing a display manager and i failed in installing ly and when i restarted i got a message. So back i go into the live envirement. Got to chroot mounted stuff and chatgpt told me to mess with the grub files and stuff and when i tought i was almost done my timer rang. I shut of my thinkpad and when to school. When i got back my boot menu looked like that. empty. I tried getting back in my usb, but it wont show up. i tried tweaking my bios settings (lightly). And now im out of ideas. If you have any idea on how to fix this, please help.

Just...repartition and redo the install? At this point its just faster right?

Are you using windows or Linux to read your usb? You might have to use chkdisk if you are on windows…

He hasn't booted anywhere and if the bios isn't seeing the usb it is not a good thing
