EDIT, SOLVED
Hey all, thanks for investin your time and pushing forward on aiding me into this, by the end of the day I was able to chroot and re install all my linux6 515 and so on through USB Live 
I don’t know how I can share the backlog of my procedures here so that it can aid others in the future
ORIGINAL POST
Hey Manjaro community, 
I thank any and all of you going through this in advance, I’ve been slowly but surely learning a thing or two of the system since the last 2 years, still there is so much to go, I’ll try my best conveying info here, this matter seems somewhat simple.
The Classic shutting down during update happened. 
Being a tad more detailed and precise here, I left it updating with enabled overwrites and with the notebook screen/lid half-shut. It went into a block-screen which, hours later, I could not get out of. Leaving me (at my knowledge level) with the option of shutting it down or unplugging and leaving battery shortage to do it for me. 
Now once powering on again I get the following:
error: file '/boot/vmlinuz-6.1-x86_64' not found.
error: you need to load kernel first.
Press any key to continue..._
Attempting to fix it through booting with a live USB and doing chroot I was returned with:
[manjaro@manjaro ~]$ manjaro-chroot -a
grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map.
==> ERROR: No Linux partitions detected!
I’ve fixed this once about 3 months ago, but there was an extra spice at that time due to some new kernel issues. This time around I’ve gone through what seemed to be similar errors, but was unable to perform the fix.
Here is some Kernel info:
[manjaro@manjaro ~]$ mhwd-kernel -li
Currently running: 5.10.42-1-MANJARO (linux510)
The following kernels are installed in your system:
warning: database file for 'core' does not exist (use '-Sy' to download)
warning: database file for 'extra' does not exist (use '-Sy' to download)
warning: database file for 'community' does not exist (use '-Sy' to download)
warning: database file for 'multilib' does not exist (use '-Sy' to download)

warning: database file for 'multilib' does not exist (use '-Sy' to download)
And here some block storage info:
[manjaro@manjaro ~]$ lsblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME
PATH PTTYPE PARTTYPE FSTYPE PARTTYPENAME
/dev/loop0
squash
/dev/loop1

/dev/sdb dos iso966
/dev/sdb1 dos 0x0 iso966 Empty
/dev/sdb2 dos 0xef vfat EFI (FAT-12/16/32)
/dev/sr0
I saw that with btrfs I would not be able to chroot, so I tried the following (for no avail):
[manjaro@manjaro ~]$ sudo mount -o subvol=@ /dev/sda1 /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.
[manjaro@manjaro ~]$ sudo mount -o subvol=@ /dev/sda2 /mnt
mount: /mnt: mount(2) system call failed: No such file or directory.
Down below, I’m adding some system info, maybe it is overkill/oversharing but I really don’t know at this point. I’m thinking that might aid on something?
One thing I’d point out is the mirrors, as I was introduced to Linux by a very dear friend that aids me here and there with the system (he is a seasoned Arch user), we ended up updating some mirrors once solving some other issues… bear that in mind. The huy is still a dear friend, I’m trying to do good for me and him on learning my stuff now
