yum installation related problems

this problem has really disturbed me for quite a while.
#the problem
#yum update

Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

so here is he solution

first u need to make some changes in these two files
/etc/yum.repos.d/fedora.repo and
/etc/yum.repos.d/fedora-updates.repo

Now un-comment all the lines that start with the term baseurl and place a comment before all lines that start with mirrorlist. Do this for both the above files.then
edit your /etc/hosts file and append the following to it’s contents:

80.239.156.215          mirrors.fedoraproject.org
213.129.242.84          mirrors.rpmfusion.org

Now try updating your system or installing any software via Yum. You will see, the error is now resolved and the error message is not shown anymore.

Adding the RPM Fusion repositories during install

FOR Adding the RPM Fusion repositories during install do this:)
Note:Before you start installing Fedora making sure you have a supported network card and over which a connection to the internet can be established. Start the install and move through the different anaconda screens where you select language, keyboard layout, root password and target volume until you get to the Additional Tasks screen:
then click on
add additional software repositories

Then follow these steps to enable the RPM Fusion free repository:

1. In the Additional Repositories section, click the Add additional software repositories button.

2. In the Edit Repository dialog, set the Repository name: 'RPM Fusion Free'

3. Set Repository type: HTTP/FTP

4. Set Repository URL depending distribution version and the architecture. For Fedora 10 on i386 use

   http://mirrors.rpmfusion.org/free/fedora/x/i386  note:where x is version of fedora

5. Click URL is a mirror list

6. Click OK

Notes:

• For other architectures like x86_64 or PPC/PPC64, change i386 to x86_64, ppc, or ppc64 in the repository URL.

• Packages in the nonfree repository require packages from the free repository to be available, hence you must enable the free repository if you want to enable the nonfree repository.

• If you enable the Fedora Updates repository during install then you have to activate the RPM Fusion Updates repositories during install in addition to the RPM Fusion Release repositories. The URLs for the Updates repositories are similar to the ones for the release repositories. Some examples:

  Repository	URL for i386
  RPM Fusion Free Release for F10	http://mirrors.rpmfusion.org/free/fedora/10/i386
  RPM Fusion Nonfree Release for F10	http://mirrors.rpmfusion.org/nonfree/fedora/10/i386
  RPM Fusion Free Update for F10	http://mirrors.rpmfusion.org/free/fedora/updates/10/i386
  RPM Fusion Nonfree Updates for F10	http://mirrors.rpmfusion.org/nonfree/fedora/updates/10/i386

Back up your MBR

Backup MBR with dd command

Backing up partition is nothing but actually backing up MBR (master boot record). The

command is as follows for backing up MBR stored on /dev/sdX or /dev/hdX :
# dd if=/dev/sdX of=/tmp/sda-mbr.bin bs=512 count=1

Replace X with actual device name such as /dev/sda.

Now to restore partition table to disk, all you need to do is use dd command:
# dd if= sda-mbr.bin of=/dev/sdX bs=1 count=64 skip=446 seek=446

Recovery problems

Bootrec.exe tool in the Windows Recovery

It repairs the following items in Windows Vista:
• A master boot record (MBR)
• A boot sector


To run the Bootrec.exe tool, you must start Windows RE(recovery environment). To do this, follow these steps:
1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec.exe, and then press ENTER.

Note: This is only possible with windows vista recovery cd which you can get with vista installation cd/dvd or from

net you can download it.

Bootrec.exe options
The Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation.

Note: If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run

this option again. By doing this, you make sure that the BCD is completely rebuilt. To do this, type the following

commands at the Windows RE command prompt:
• bcdedit /export C:\BCD_Backup
• c:
• cd boot
• attrib bcd -s -h -r
• ren c:\boot\bcd bcd.old
• bootrec /RebuildBcd
/FixMbr
The /FixMbr option writes a Windows Vista-compatible MBR to the system partition. This option does not overwrite

the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to

remove non-standard code from the MBR.
/FixBoot
The /FixBoot option writes a new boot sector to the system partition by using a boot sector that is compatible with

Windows Vista. Use this option if one of the following conditions is true:
• The boot sector has been replaced with a non-standard Windows Vista boot sector.
• The boot sector is damaged.
• An earlier Windows operating system has been installed after Windows Vista was installed. In this scenario,

the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).
/ScanOs
The /ScanOs option scans all disks for installations that are compatible with Windows Vista. Additionally, this

option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista

installations that the Boot Manager menu does not list.
/RebuildBcd
The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista. Additionally, this

option lets you select the installations that you want to add to the BCD store. Use this option when you must

completely rebuild the BCD

Reinstalling Grub boot loader
BY
COMMANDS @ TERMINAL
COMMANDS TO REINSTALL GRUB:
U just need to enter the terminal using the installation CD/DVD of your GNU/Linux operating system.

Once you are at the terminal. type this:
$ grub
If it says that you don’t have the permission. Type this command at the terminal:
$ sudo grub
You will get the grub-shell prompt:
grub>

Now, you need to find out in which partition Grub had been installed before, so that you reinstall in that

partition only. Give this command at the terminal:
grub> find /boot/grub/stage1
(returns value)
It returns the number of the partition in which Grub i.e your GNU/Linux had been installed.
e.g.,

grub> find /boot/grub/stage1
(hd0,2)


NOTE:
Sometimes, when Grub has not been installed properly, the file “/boot/grub/stage1″ may not exist. So, the output

will be “Error 15: File not found”. In such a case, come out of the grub-shell by pressing “Ctrl+c”. Then, at the

shell prompt, give this command at the terminal:
$ fdisk -l
Again, if you are not logged in as root, give this command at the terminal:
$ sudo fdisk -l
The output will list all the partitions and it’s properties, including the file system type.
e.g.,
Device Boot Start End Blocks Id System
/dev/sda1 1 654 5253223+ b FAT32
/dev/sda2 * 655 1962 10506510 7 HPFS/NTFS
/dev/sda3 1963 3924 15759765 83 Linux
The “System” attribute of your GNU/Linux operating system will be “Linux”. So note down that partition number.
e.g., sda3
Since it’s array numbering, sdaN is mapped to (hd0,N-1).
Just (hd0) will be the Master Boot Record(MBR).
sda1 will be (hd0,0) and so on.
So, sda3 will be (hd0,2)
Now, log into the grub-shell prompt again.

Before reinstalling Grub, you will have to notify the partition that your Grub i.e. GNU/Linux is resided in. So,

give this command at the terminal:
grub> root (returned value)
e.g.,
grub> root (hd0,2)

Now, reinstall grub in the MBR i.e. the returned value without number part.
e.g., (hd0)
So, give this command at the terminal:
grub> setup (returned value without number part)
e.g.,
grub> setup (hd0)

Exit the grub-shell prompt using “Ctrl+c”.
Exit the shell prompt using “Ctrl+d”.

NOTE :

You can also reinstall Grub in your GNU/Linux partition, only if this GNU/Linux partition is “primary” and you have

another boot loader installed at the MBR(in case of more than one GNU/Linux operating systems) through which you

can boot this primary partition. To do that, give this command at the terminal:
grub> setup (returned value)
e.g.,
grub> setup (hd0,2)
