@renate has a great point.
Running any intensive operation (booting the OS is one) on a dying disk is like having a heart attack patient run up hill to the doctor.
The first thing I would do is clone the drive (I like Clonzilla. It is a bootable app).
A USB cloneing hardware kit is cheap. It allows the replacement drive to temporarily be attached.
I have an earlier version of this

It is also handy for just checking what is on any loose drive you had on a shelf.
(The cloneing does ONE read on the failing drive)
Once the CLONE is installed, then you run the file repair.
Clonezilla is my fav because it handled dual boot drives, allows the clone to also grow (the partition gets more space)
