All day today, I've been reformatting a USB flash drive repeatedly and I was doing this multiple times in a row, and I began to grow a little too careless...
Without paying attention, I accidentally reformatted my /dev/sda1 in the GNOME Disks manager utility in Fedora. I didn't overwrite all the data with 0s, but instead just did the quick rewrite.
After rebooting, my mistake was made clear when my laptop immediately booted into rescue grub mode.
I know /dev/sda1 was 512MB, so I think my actual data is safe and fine, on /dev/sda2. But is there a way I can get Fedora to successfully reboot again?
