Unable to boot my Linux Mint Xfce 32 bit system due to error message which states "fsck exited with status 4". What does this mean and how can I "run fsck manually""? I understand that "fsck" stands for file system check.
I have been using this computer with Linux since 2016; firstly , with Ubuntu 16.04 LTS and since 2019 Linux Mint Xfce until now.
I would appreciate any advice to get my computer up and running again as I am totally fed up with Microsoft and their partners.

Computer is Toshiba Satallite L300.

Original message: BusyBox v1.27.2 (Ubuntu 1:1.27.2-2Ubuntu3.3) built-in shell (ash) Enter 'help' for a list of built-in commands.
(initramfs) exit [return]
/dev/mapper/mint--vg-root contains a file system with errors, check forced.
Inodes that were part of a corrupted orphan linked list found.
/dev/mapper/mint--vg-root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e. without -a or -p options)
fsck exited with status 4.
The root filesystem on /dev/mapper/mint--vg-root requires a manual fsck.
