how to uninstall kubuntu in these special circumastances ?

[eslam elbyaly]

Well I fear that this situation is not going to be recoverable without a complete disk format...
However you might wish to wait before rushing to format in case someone else here has a better solution.
If you have no files or other data you want to save then IMO this is the best solution.

While you wait you might want to think about what disk layout would best suit what you want to do, e.g dual-boot with WinXP and Ubuntu/Kubuntu.

what is (IMO) ?

i repeat ,
1- my xp cd is working very well on any other pc .
2- i do not mind to delete the ext4 partition , this is what i want , but what i mean is , even when i 'am able to install xp , then i delete the ext partition , then my windows boot loader will crash , since this what i did at the first .
thanks

Some questions;

1. Do you own a copy of WinXP installation disk?
2. Do you have a copy of GParted on disc?
3. How much personal/saved data is still on your windows partitions?

For an individual desperately requiring help you pose a lot of questions of your own, and yet fail to completely answer those asked of you.

I think you should ask some friend that knows more about computers to help you. I tried helping in your other thread too, but it's almost impossible since you are asking too many questions about everything, so instead of solving the problem it just takes forever. You have to understand that we can only give you guidance, we can't make the choices or hit the buttons for you. You have to make some choices yourself.

How did you check that the hdd is not seen on another computer? In windows? Windows is very limited when reading disks with errors in the partition table. You can't rely on that.

The best is to use linux tools and testdisk for example.

Another thing is booting the laptop from a cd. Are you sure you have set it up correctly? The cd-rom needs to be before hdd, otherwise it will try booting from the hdd. You can also try the Boot Menu that most computers have, usually you have to press a key on boot like F12, but it might be a different key on your machine. Watch the message during boot.

It should be able to boot from cd in any case.

If you manage to boot from the ubuntu cd in live mode, you can still try saving the data. Otherwise, if you can boot the XP cd you can format the disk and install XP.

In the case if the hdd is really dead, there is not much we can do for you.
