HI all,
finally managed to dual boot manjaro with pre-installed win10 on my dell…
the issue now is that i’m not able to upgrade the packages.
The gui hangs…
on terminal,
sudo pacman -Syu returns
unable to synchronize packages
Help please!!! I need to install a few more packages and start with my photo/video edits soon…
System: Dell latitude 5400, Windows 10 OEM, and manjaro gnome lysia
Welcome to the forum! 
sudo pacman-mirrors -f 5 && sudo pacman -Syyu
That’s a -Syyu instead of -Syu, because you’ll be using a different mirror list for the first time now.
First update always require - to force download of database
sudo pacman -Syyu
There is no database after install.
Thanks a lot ppl…
the gui worked after a reoot…
now, that the packages have been upgraded, and i rebooted the laptop, i am not able to boot manjaro at all!! ’
grub shows up, gives me the option of windows boot manager, manjaro linux and advance options for manjaro linux, but on selecting any of the linux options, the screen freezes at the dell logo, and doesn’t move further…
Had the same experience earlier, and had to remove and rebuild the boot manager so that the manjaro efi was removed, and the laptop went back to it’s original state…
Is there a command line fix from grub i can use to fix this?
Your system might be low on entropy. It might help to install haveged. 
sudo pacman -S haveged
sudo systemctl enable haveged --now
If you cannot get your system to boot up from the installed Manjaro, boot up from the install medium, open up a terminal, and issue the following command…
su -
Then issue the following command…
manjaro-chroot -a
Select your Manjaro root partition if it’s not automatically detected, and then issue…
pacman -S haveged
systemctl enable haveged --now
exit
The above does assume that you’ve successfully update your system earlier.
@Aragorn
thanks for the update… Might sound silly, but I’ll still ask a newbie kinda doubt… this I do with my live usb, right?
the system has been updated, that’s for sure… While I do this, is there any way from grub shell/command line…

Who is faster ? i thing the 2nd .
Tried the haveged, but couldn’t execute the chroot…
here’s the screenshot
~ >>> manjaro-chroot -a
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.

Now what??
Testing … Press 1 not 0 ?!
Yes, that is correct.
Then we’re going to have to chroot manually, but given that you haven’t given us much information, we have no idea on how to proceed.
Hi all!!
Sorry couldn’t write back earlier, since couldn’t sit on the laptop for a few days. But here goes anyway…
@Lila-Kuh
Thanks!! the [1] did work…
But then this is what happened next
~ >>> manjaro-chroot -a [127]
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.

@Aragorn
The system is a UEFI boot, and both the bootmgr are on EFI system partition only… The MBR was modified during the manjaro install.
Try this (in the chroot)…
grub-install --recheck --no-rs-codes --efi-directory="/boot/efi" --target="x86_64-efi" --modules="part_gpt part_msdos zstd"
update-grub
Note: I have edited your post in order to reformat your terminal output. When pasting terminal output into a post, please use the </> button in the toolbar of the post editor.
nope…
doesn’t work
in-fact, after rebooting the machine, i don’t even enter grub menu!!
All i get is the Dell logo flashing for a couple of times, before freezing… Had to reboot again and use f12 for boot menu
Either I try to do a fresh install/dual boot - if anyone could pls help me through it… or is there a way out?
Hi all…
Strange turn of events…
I used bcdedit in windows terminal to set boot to Manjaro. And then suddenly windows stopped booting and Linux started to boot…
I frantically searched for a rescue, managed to update grub again to get back to normal and windows was booting again… but Linux stopped booting…
In this search, I looked around for a grub option… and finally did manage to get into grub rescue mode… this was the output I got
grub rescue> ls
(hd0) (hd0, gpt6) (hd0, gpt5) (hd0, gpt4) (hd0, gpt3) (hd0, gpt2) (hd0, gpt1)
grub rescue> set
cmdpath=(hd0,gpt1)/EFI/Boot
prefix=(hd0,gpt5)/boot/grub
root=hd0,gpt5
So now, how do I work from here?
The boot partition is same, but the mount and swap are different… how do I find out which is which here?
