I was using the Arch Linux bootable USB installer on my Samsung NT270E5R laptop. I accidentally unmounted all the drives during the session when I was trying to reinstall the grub bootloader for my Debian installation. I wasn't making progress doing that, so I restarted the laptop normally, and now it gets stuck showing Samsung's logo. I waited for hours, but it didn't boot into Debian. I have a previous grub bootloader installed in my MBR, so I'm not sure what the problem is.I tried to hard reset the laptop, tried accessing the BIOS setup with F10, and tried booting into both Arch Linux and Windows 10 live CDs, but none of those things worked. What else can I try?
Unable to boot after unmounting drives while in use
debian;boot
