Fix Arch [Manjaro] GRUB Bootloader

 Boot to any [Manjaro] live GUI disk.

Use manjaro-chroot

1. Start by identifying the partition where your Manjaro installation controlling the active Grub menu resides and needs repairing. If you are in Graphical mode you can use an application called GPartEd, which should be in Menu > System > GPartEd. This will provide a simple visual illustration of the partitions on your hard drive(s).

To do the same thing from terminal or TTY you can use this command 

lsblk -f


2. manjaro-chroot is a tool to easily setup a functional chroot into an installed Linux installation from a live boot of a Manjaro Installation Media.

To setup the chroot use the command 

sudo manjaro-chroot -a

You will be presented with a terminal. Wait until it shows a list with the available system partitions on your computer and choose the one you want to repair. 

 

1.) First of all check the partition for the ESP (EFI System Partition). An ESP is a fat32 partition and contains .efi files for booting.

It can be checked using Gparted or from the terminal using fdisk -l


(Note: If you do not have a EFI partition, you will need to create it. Use Gparted for that.

Type- fat32

Size- 512 mb to 1 gb)


2.) Create the /boot/efi directory 

sudo mkdir /boot/efi


3.) Mount the EFI partition as /boot/efi 

sudo mount /dev/sdXY /boot/efi

X = Alphabet of the drive = a,b,c ... Y = Partition number of the EFI partition = 1,2,3,4...

Example - /dev/sda4


4.) Re-install Grub. 

sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck


5.) Update Grub configuration file. 

sudo update-grub

Edit deb files (iOS tweak Installation/Linux Debian)

To unpack the package, create an empty directory and switch to it, then run dpkg-deb to extract its control information and the package files.  Use dpkg-deb -b to rebuild the package. mkdir tmp dpkg-deb -R original.deb tmp # edit DEBIAN/postinst dpkg-deb -b tmp fixed.deb Beware that unless your script is running as root, the files' permissions and ownership will be corrupted at the extraction stage. One way to avoid this is to run your script under fakeroot . Note that you need to run the whole sequence under fakeroot, not each dpkg-deb individually, since it's the fakeroot process that keeps the memory of the permissions of the files that can't be created as they are. fakeroot sh -c ' mkdir tmp dpkg-deb -R original.deb tmp # edit DEBIAN/postinst dpkg-deb -b tmp fixed.deb ' Rather than mess with permissions, you can keep the data archive intact and modify only the control archive. dpkg-deb doesn't provide a way to do that. Fortunately, deb packges are ...

Wine Installation X Error

Error: configure: error: X 64-bit development files not found. Wine will be built without X support, which probably isn't what you want. You will need to install 64-bit development packages of Xlib/Xfree86 at the very least. Use the --without-x option if you really want this. Solution: sudo apt-get install xorg-dev
