Linux won't load, what should I do?

Question

GRUB

I decided to put Gentoo on the laptop, as a result, I reinstalled some, I don’t remember which one, once with the same problem. When loading, say that, checking local filesystems ... and get up. It doesn't move further. I looked at the English-language forums, it seems that something is related to /etc/fstab. It was written by hand and generated using arch livecd with the genfstab command. Did not help. /etc/fstab :

# /dev/sda7
UUID=d6243af5-4c20-48a4-8897-796019b42b28	/         	ext4      	rw,relatime,data=ordered	0 1

# /dev/sda2
UUID=5fe1dc80-3bfc-4423-8cd4-fd0d3306ee78	/boot     	ext2      	rw,relatime,block_validity,barrier,user_xattr,acl,stripe=4	0 2

# /dev/sda6
UUID=a9434740-8fda-43b7-b29b-9afc3c30b8e1	none      	swap      	defaults  	0 0

blkid output:

The laptop also has mint, which grub-mkconfig refuses to find. Maybe it's somehow related. Tried googling, but it didn't work. I have no idea what is even going on. Ran it through fsck, didn't work.
