I recently installed Ubuntu on my laptop, dual booting with Windows, with GRUB as the boot manager.
Earlier today, I booted into Windows and shrunk the Windows partition. After attempting to reboot into Ubuntu, I got a GRUB shell saying Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. followed by grub>. In an attempt to fix this, I booted with my Ubuntu live USB to install and run boot-repair. When I did this, boot-repair got stuck in a loop saying filesystem repair requires to unmount partitions. Generating a BootInfo file gave me this.
/dev/sda is referring to the live USB stick I am using. /dev/nvme0n1 refers to my SSD, where Windows and Ubuntu are installed. Opening GParted shows an exclamation mark next to /dev/nvme0n1p7 (dumpe2fs: Invalid argument while reading journal inode), as well as /dev/nvme0n1p8 and /dev/nvme0n1p9 (similar errors for both):
Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/nvme0n1p8 is missing
These two partitions used to be detected as the Ubuntu primary partition and the swap partition, respectively. If I run fdisk -l, it actually lists them both with a type of Linux filesystem.
What is likely to have gone wrong, and how do I go about fixing it?
