I have a Windows 10 laptop. I installed ubuntu on it and messed up the windows boot loader months ago, but ubuntu 19.04 (recently upgraded) works. I've recently started trying to fix the bootloader, and I was following the instructions here.
I ran these commands
sudo apt-get install syslinux sudo dd if=/usr/lib/syslinux/mbr/mbr.bin of=/dev/sda3 sudo apt-get install mbr sudo install-mbr -i n -p D -t 0 /dev/sda3
sda3 is my windows data partition. I think I misunderstood what the instructions said about "Don’t forget to replace “sda” with the Windows 10 system drive." but idk.
Now I cannot access the files on /dev/sda3 and I'm worried that even if I do fix my windows bootloader that now it won't be able to load the data!
How can I get access back to /dev/sda3 and view the files on it?
mount /dev/sda3 mount: /dev/sda3: can't find in /etc/fstab.
