System can't start after update 06.07

Hello

Today I have installed update 06.07 (I guess that) and after that I can’t run my manjaro. When computer starts it only shows me GRUB_ on black screen and nothing else. My manjaro XFCE is installed on separate disk, everything was fine until this update. What can I do?

Greetings

PS. (I could not post it under update thread)

No solution found here?

Do you mean the Grub prompt, or after grub selection to black screen with a cursor at top-left?

Yea, GRUB with a cursor at top-left part of screen but I can’t even see list of installed systems. Turn on computer-> BIOS things (computer specification and so on)->GRUB in top-left corner

Like this?

grub>

If yes, try this to get into your installation.

More like:

GRUB

I tried this, it boot up my system but when I turn off my computer and turn on, problem appear again.

IIRC that topic advices to re-install grub and investigate - repair the problem (grub failure). Have you done any repair action?

When I try to run sudo install-grub /dev/sda:

Installation for the i386-pc platform.
grub-install: note: this GPT partition label does not have a boot partition BIOS; deposition will not result.
grub-install: note: Embedding is not possible. The GRUB program can be installed with these settings only on the block list. And, blocking is UNCERTAINTY, there is not recommended ..
grub-install: error: no use is continued using the block list.

sudo update grub works fine but do not take any effect

Also, when I booted successfully my manjaro from installation media there was a error (occurred for a second) like “grubenv not found”

ooo… is this manjaro32 ?

What do you mean? 32bits? No, it is 64bits version from the official website

EDIT; Tried to run grub-install on /dev/sda4 where boot partition exists but still got these errors

Boot to your Manjaro installation (like you did) and at a terminal run these and return the outputs here in proper code tags </> :

inxi -SMCDPIxxxz
pacman -Qs grub
fdisk -l | grep Disk
lsblk

Also confess: how many OSes do you have on this PC?

You are trying to install a bios-legacy grub in a gpt partitioned device.
You need to show “sudo parted -l”

inxi -SMCDPIxxxz

I have 2 systems on 2 separate disks 250GB - Manjaro, 750GB - Windows 7 (currently pin off due to this problem)

Show all disks.

We need to see the $esp partition for windows.

Lucky for you that you provide the whole ‘parted -l’ (lucky because we would have advised you wrongly by assuming windows is uefi)
Your windows is bios-legacy and widnows disk is msdos, not gpt.

Your Manjaro is also bios-legacy but you are suing a gpt disk for it.

Suggest you reinstall Manjaro.
But first make your manjaro disk msdos, not gpt.

That will wipe out evrything in that disk.
Then reinstall manjaro.
