hardware compatiblity or some other problem,.,

That's right my friend.

He/she may need to backup personal data to dvd before trying this.

I strongly suggest this as a optimal solution, which may be prolong able.

If you delete a partition it may cause more problems down the road.

Like partitions being out of order.

Currently, as seen above, My home dir is sda6, but actually resides at the end of the drive,

which should be sda13, but that was because I changed the sizes of the minor partitions.

Once you have corrupted the file system so much a clean install is recommended.

Like with M$Win, repartition, reformat and reboot.

After all, It's just a PC.

Hi doesn't have a bootable Live-CD yet.
I'm using Slax in such cases, a small Slackware-based Live-CD http://www.slax.org/ which can also be used with a USB-drive.
This has to be tested before altering the partitiontable, a bootable CD must be available.

Marcus i do have ubuntu 9.10 live cd and i can reboot from tht if some problem occurs ,,but the problem is tht if some problem did actually occur i may not be able to use the net and thus my contact with u guys will be broken and i wont be able to do anything without help from u guys....ubuntu is working fine and
as u have said to delete the partition /dev/sda3 ..i guess tht was my swap partition and dev/sda2 is just my independent data partition tht i created with the help of gparted.
actually i wanted to make an independent data partition as my hard disk small only 40 gb..so tht if in future i wanted to try some other distro i can do so without affecting the data stored on the independent partition ....
dev/sda one is the / mount point ext4 and dev/sda3 was the swap ...but it is showing something else in the gparted as "unknown"......dont know what is this happening ...
guys please tell me if this problem can be solved or is it just going to waste ur time and mine too......whatever the case may be i am able to learn a lot of things in association of u guys and i thank a lot to all the participants in this thread ..all of u are great guys ..all the best and god bless u all

yes i have removed all the personal data from my computer now into dvd and usbs available to me ..and i am a guy not a girl ..heee

GlennsPref · 12-09-2010, 04:32 AM

Linux is able to survive with a / and swap partitions.

so, maybe you can squeeze to a 15Gb partition.

But it won't be big enough to continue for long.

That may give you the opportunity to get the mandriva system running.

But then you (he) may have to consolidate you other dirs to make room for you.

If you have no real data to keep, just go for it and delete all the partitons and start again.

Backup to dvd if you can.

Cheers, Glenn

sinvikram · 12-09-2010, 04:46 AM

so u want tht i should delete all the partitions. ok will do tht ..but should i delete /dev/sda1 also on which ubuntu is installed??? ,,,hhmmm if u have somethng else to say before my doing so kindly tell me ,,becoz after my doing so ..it may take time for me to actually post here so quickly.....sir GlensPref and markush sir ...give me ur last instructions before i can proceed further....
hoping against the hope .tht it may work

GlennsPref · 12-09-2010, 04:48 AM

If you cam make it work with out repartitioning sda1 well and good, but if not, you can always re-install it.

regards Glenn

GlennsPref · 12-09-2010, 04:57 AM

But leavind sda1 should be OK.

That should (but may not) give you enough to re-gain you Operating system as well as a new system like Mandriva..

Personally I find Mandriva to be the most configurable OS in existence, although I have not tried slackware (I use slax live) or gentoo, but my superiors/gurus do.

Always remember, Linux is the Kernel (applicable to all GNU/Linux systems.), not just the desktop.

I care so much, that I will post you a dvd in the mail if required. Just let me know!

3 or 4 dollars is easy.

Regards Glenn.

sir Glanpref hmm u seem to be so generous yes i am desiring to request you for the dvd. as a kind of blessing from a superior like u it will be great as long as it is not a burden on ur pockets as i live in India and mailing a dvd costs a lot i guess...thank u very very much for ur kindness...meanwhile i can try what u have told me if tht worked will let u know ....thank u once again

After all in my opinion a clean install is the best choice to get the system working over long.

I would do the partitioning manually with fdisk (or cfdisk).

As an example: /dev/sda1 8GB, /dev/sda2 8GB, both / partitions for a Linuxsystem. /dev/sda3 1GB swap.
/dev/sda4 extended, the rest of the disk. /dev/sda5 logical /home for Ubuntu, /dev/sda6 2GB /home for Mandriva, the rest /dev/sda7 about 19GB mounted in /usr/local/public on both, Ubuntu and Mandriva.

This is similar to my setup. The seperate homepartitions are useful in order to use different versions of programms (which is inevitable when using different distributions). The public-directory will store most personal data.

Here my system as an example: df -h

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/root              35G  9.2G   24G  28% /

but what i actually trying all this is for the following reason: i wanted a separate personal data partition which can always remain safe even if somethng wrong happens in the system or i have to try a different distro or any other situation......as the hard disk is just 40 gb and i wanted tht the / should be 10 gb and i gb swap and the restr for extended ondependent data partition ...thanks

markush · 12-09-2010, 05:33 AM

Well, my partition which is mounted in /usr/local/public is independend, it stays unchanged when I install another distribution.

Be aware that "really independend" is only a separate disk since if the disk crashes the data are lost anyway.

Markus

GlennsPref · 12-09-2010, 05:58 AM

It's a good idea to have /usr/local on a separate partition as long as the source directories are accessible.

Like /home/$USER/programs

Then if you upgrade the system all you need to do is reinstall the programs.

But if you upgrade glibc.so you'll probably have to start again (remake) because the libraries version has changed.

So, don't upgrade glibc.so unless you have to.

yes, you're right, but with Gentoo it's no problem and with Slackware I do always a reinstallation when upgrading libraries.
As I wrote above Slackware comes with a minimal install-USB-boot image. I use to load all packages down (with wget), store it in the /home directory (which remains unchanged) and then use the option "install from a premounted directory". I've done this with a fast Laptop with a downtime under 8 Minutes

... well, I'm using Slackware since more than 16 years...

Hi, above, #2, I mentioned some cli switches to use with the kernel.

The one that controls the harddrive (ide controller) is msi

Type,

Code:

pci=nomsi

Sorry this is soo... late.

I just remembered....
