Subject: Re: Can one now help?Live CD also allows you to just boot the cd without installing it.
So, do not select install. just boot it and the desktop will come up.
in desktop, open a terminal:
Click Applications -> System Tools -> Terminal
in the shell terminal, mount your fedora partition:
su -
No password needed. just press enter.
mkdir /mydisk
mount /dev/sdXN /mydisk
where X is the drive letter and N is the partition number (starts at 1) where you installed fedora.
Now cd to your /etc and edit fstab and fix the problem.
If you do not know how to do that, post the contents of your fstab to this list
and I am certain someone will tell you what is wrong.
one things is that when you say sdXN, X is the drive letter means what drive letter is give to the linux partition? in windows if i see, its H so it should be like sdH9?? in the line:
mount /dev/sdXN /mydisk
but the error i get is:
mount: you must specify the filesystem type (which comes in the terminal)

the system all over again. Instead, once you have booted the Live CD and have
the desktop show up, you should do several things.
First open the terminal (find it in the menus, its exact position depends on
KDE/Gnome Live CD, and I don't know which one you are using).
Yes, i am using Gnome and the live CD of fedora 11.Then you need to find out which partition is the root partition of your
installed Fedora. You do not want to confuse that to your *current* root
partition which is on the Live CD. Hard disk partitions in Fedora are named
sda1, sda2, ... for the master hd on the primary IDE controller,
sdb1, sdb2, ... for the slave hd on the primary IDE, then sdc1/2/... and
sdd1/2/... for the master and slave on the secondary IDE, etc. Of course, if
you have a SATA drive this may be different. If you have a dual-boot
configuration (ie. Windows), then it typically takes sda1 for Windows drive C:,
sda2 for windows drive D: (if you have one, not counting the CD/DVD drive) and
so on, while Fedora partitions go after those.
yes, its sata harddisk i think and dual booted with windows. in windows i have partitions for C, D, E, F (four drives).
I am writing all this to show you that partition layout depends a lot on your
hardware and software configuration, and no one on this list can guess it for
you --- you have to find it out yourself for your particular machine. One way
to do it is to use fstab:
(1) once in the terminal, type "su -" to become root (without quotes)
(2) type "fdisk -l /dev/sda"
(3) fdisk will list the partition table of your hard disk --- look carefully
on that list, and try to figure out which partition is the Linux root
partition. If you cannot guess it yourself, post the partition table layout to
us so we can help you with guessing.
the result of "fdisk -l /dev/sda" is as follows:
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xfedcfedc

/dev/sda9 15961 28596 101487615+ 8e Linux LVM
I don't know why there is no entry for sda3 and sda4. I guess the linux root partition to be sda8? or it should be sda9?
After you have determined which partition is the Fedora root (in what follows
I will assume that it is /dev/sda2, while you should substitute the relevant
/dev/sd?? instead), you want to mount it somewhere --- typically to /mnt
directory of your running LiveCD Fedora. This is done as follows:
(1) create a new directory in /mnt, by typing "mkdir /mnt/oldfedora"
(2) mount the partition to that directory by typing
"mount /dev/sda2 /mnt/oldfedora" (and don't forget to substitute /dev/sda2
with whatever is relevant for your case)
mounting this (for both sda8 and sda9), it shows me the error:
mount: unknown filesystem type 'lvm2pv' (in the terminal)
and once:
mount: you must specify the filesystem type (in the terminal)
so again it is not getting either mounted.
After this all, I searched the google and then, at the following web-page:
http://fedoraforum.org/forum/showthread.php?t=213000
I got some details to how mount the LVM2 and resolving the error.
I typed the following three commands first:
[liveuser@localhost ~]$ su -
[root@localhost ~]# kpartx -av /dev/sda
[root@localhost ~]# vgscan
[root@localhost ~]# vgchange -ay
After that i run the following command:
[root@localhost ~]# ls /dev/mapper
the output of which was:
control live-osimg-min live-rw VolGroup-lv_root VolGroup-lv_swap
[root@localhost ~]# mount /dev/mapper/VolGroup-lv_root /mnt/oldfedora/
after that switched to the /mnt/oldfedora/
[root@localhost ~]# cd /mnt/oldfedora
and run the ls command
[root@localhost oldfedora]# ls
which yielded:
bin dev home lost+found mnt proc sbin srv tmp var
boot etc lib media opt root selinux sys usr
Means i got to that area.
The output of the following command:
[root@localhost oldfedora]# cat /etc/fstab
was:
#

tmpfs /tmp tmpfs defaults 0 0
tmpfs /var/tmp tmpfs defaults 0 0
I don't understand why it is wrong?
But after much pondering over, I just deleted the gap between the nodiratime,noatime and defaults, and really speaking after that only i was able to boot from the original fedora.

This is 100% correct. Linux can understand quite a few file system
architectures, so you need to include a '-t filesystemname' in your mount
command line. Man mount.
yes but this was not working.
