Windows 8 and fedora 20 Dual boot in HP

Recently I have moved to fedora 20 and window 8 which showed that HP laptops have a special bios which only allows windows EFI to be loaded as default so even after installing both the OS and making the EFI partition of fedora default the system boots from Windows EFI directory. To get the grub to boot first I did the following steps.

My disk partition are as below. Device           Start          End   Size Type
/dev/sda1         2048       616447   300M Windows recovery environment
/dev/sda2       616448       821247   100M EFI System
/dev/sda3       821248      1083391   128M Microsoft reserved
/dev/sda4      1083392    122882047  58.1G Microsoft basic data
/dev/sda5    122882048    123291647   200M EFI System
/dev/sda6    123291648    124315647   500M Microsoft basic data
/dev/sda7    124315648    548470783 202.3G Linux LVM
/dev/sda8    548470784    976771071 204.2G Microsoft basic data

Here I have two EFI partition /dev/sda2 (Windows) and /dev/sda5 (Fedora). As the setting is embedded in HP bios we needed a work around.

So I mounted the partititons first .

mount /dev/sda5 fedora/
mount /dev/sda2 win/

Now we copy the Fedora EFI content to Windows partions as follows

cp -rp fedora/EFI/fedora win/EFI/

In the windows partion you can find a default HP EFI content . Just rename it to some thing else.

Now rename the windows boot loader

mv win/EFI/Microsoft/Boot/bootmgfw.efi  win/EFI/Microsoft/Boot/bootmgfwB.efi

Now copy the grubloader into the place of windows bootloader

cp win/EFI/fedora/grubx64.efi win/EFI/Microsoft/Boot/bootmgfw.efi

Now recreate the grub.cfg and place it in win/EFI/fedora

grub2-mkconfig -o win/EFI/fedora/grub.cfg

It should be done by now reboot the machine and check it .

BYPASS FEDORA PASSWORD

1. Reboot the system
2. When you see the Grub menu, highlight your Fedora installation with the arrow keys and press ‘e’ to edit.
3. Again use the arrow keys to highlight the line saying ‘kernel’ at the beginning and press ‘e’ again, which will let you edit that line.
4. Append a space at the end of the line and type ’single’ without the quotes there. Press the Enter key.
5. Now press ‘b’ which will take you to the Linux single user mode where you’ll have privileged access without typing a password.
6. Now you do a passwd, and change your root password. Then reboot. You are done.

Now enter into TTY mode and login as root and use passwd "username" to change the password of needed password

enjoyyyyyyyy............

Enable Install Software Package from Fedora DVD/CD

List the file inside yum repo configuration directory... you can use the ll command as show on example below or replace the ll command with ls -l command.if needed first try "yum install repo"
 1.>>>>>>>>>ll /etc/yum.repos.d/

To make Fedora DVD as installation source... we need to create DVD repo file and edit this file to make the Fedora DVD as the installation source.  To make life little bit easier,  just copy the existing yum configuration file fedora.repo and name the copied file as fedora-dvd.repo
2.>>>>>>>>>cp -pr /etc/yum.repos.d/fedora.repo /etc/yum.repos.d/fedora-dvd.repo

3.>>>>>>>>>ll /etc/yum.repos.d/

Execute command below to open and edit the fedora-dvd.repo configuration file using gedit editor... edit the configuration file.. rename the repo as "[fedora-dvd]", and "name=Fedora-dvd" add PATH to the Fedora 11 DVD "baseurl=file:///media/Fedora%2011%20i386%20DVD/" and enable the Fedora DVD repo file "enabled=1 "see... working example below... and then remove unwanted line from the fedora-dvd.repo configuration file.
4.>>>>>>>>>gedit /etc/yum.repos.d/fedora-dvd.repo &

[fedora-dvd]

name=Fedora-dvd $releasever - $basearch

failovermethod=priority

baseurl=file:///media/Fedora%2011%20i386%20DVD/

enabled=1

metadata_expire=7d

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

....Save and exit the editor

**change the baseurl as per the dvd version u use**
5.>>>>>>>>>yum clean all

To start to use Fedora installation DVD as installation source, execute yum command and temporary disable all other repo except Fedora DVD repo using the command that show on example below.  Change the gcc part to the software that you want to install in your box
 6.>>>>>>>>yum --disablerepo=\* --enablerepo=fedora-dvd install gcc*

 

 

CREATE LOCAL YUM REPOSITORY

1) Copy all the RPMS from the DVD to a particular folder lets say /root/os/RPMS

2) Install createrepo RPM from /root/os/RPMS directory using rpm command

3) Now, we will have to create repo of the directory in which we have coied the RPMS. Following is the command to create the repo
.........>createrepo /root/os/RPMS

Once the above command gets completed you will find repodata directory in /root/os/RPMS folder

4) configuing YUM to work with local repository. Create a new file in /etc/yum.repo.d/ or open /etc/yum.conf and paste following
[local repo]
 name = OS $release - MyLocalRepo
baseurl = file:///root/os/RPMS/
enabled=1
gpgcheck=0

Now Try to install any package using YU
