ok, so its on sda1, so chroot:
sudo cryptsetup -v luksOpen /dev/sda1 cryptDrive
sudo mount /dev/mapper/cryptDrive /mnt
sudo manjaro-chroot /mnt
and post output

hi, What may i do next?
well you are not chrooted… so try unmounting it:
sudo umount /dev/sda1
then type:
exit
close terminal, open terminal again, and try chrooting, but run the commands one at a time:
sudo cryptsetup -v luksOpen /dev/sda1 cryptDrive
then:
sudo mount /dev/mapper/cryptDrive /mnt
and:
sudo manjaro-chroot /mnt

please pardon me for delayed response. electricity was gone .
could you please tell me what may i do next?
i hope i will not lose data.
i dont use encyption so have no idea whats with it… but i found another guide for chrooting luks, so try that:
sudo cryptsetup luksOpen /dev/sda1 crypto
sudo mount /dev/mapper/crypto /mnt
sudo manjaro-chroot /mnt

Brahma, my friend, i am very grateful for your kind efforts and time to help me. but i am also sad that i am giving you trouble even though i dont want to. what a helpless situation i have.
i have no knowledge about encryption, since i dont use it, and this is one of the reasons…
try running this:
sudo umount /dev/sda1
and:
sudo cryptsetup close encrypted
and then run again:
sudo cryptsetup -v luksOpen /dev/sda1 cryptDrive
and post output from it

Brahma, what if there might be something wrong with the grub? i guess. maybe.
you may like to check whether all the settings in my grub is correct.
so here it says that its not mounted:
and here it says that it is mounted:
i dont understand…
try this:
dmsetup remove_all
and then again:
sudo cryptsetup -v luksOpen /dev/sda1 cryptDrive
this is not related to grub…

i will do it now. it may take 2-3 minutes.
Hi it says. You can’t embed media items in a post. What should I do?
so it worked? the commands showed output?
you still not allowed to post pics here, since you are a new user…
you can upload the pics on some image hosting website and post the link here, and use formatting for the link
