Accidentally Set Partition as A Swap Point

Hello,

So as I was trying to create a swap partition, I accidentally mixed up the device addresses and picked the wrong one. If I was supposed to enter:

sudo bash -c "echo UUID=$(lsblk -no UUID /dev/sda7) none swap defaults 0 0 >> /etc/fstab"

I instead entered
sudo bash -c "echo UUID=$(lsblk -no UUID /dev/sda3) none swap defaults 0 0 >> /etc/fstab"

So sda3 instead of sda7. The problem is that now I can’t mount the sda3 anymore since it’s written to fstab. I think it’s also affected the boot process. Could I have some instructions to rectify this, please?

Thank you

Chroot into installation and edit fstab with correct entries. Hopefully it’s only this.
Mount partitions manually, if -a doesn’t work. (sorry I don’t understand what isn’t working exactly)
