I phoned to the PC shop and they told me that my hard disk is under guarantee.Since the hard disk has got 28 bad sectors I can change this hard disk(.this was a samsung hard disk but they tell me that seagate is the best now).But in order to change this hard disk I have to give this disk to them and wait approval for a week!!!! So that means I will not be able to use my PC for some time and also I have to format the sensitive data.I do not like the situation.Is there a way to completely copy this system to another hard disk(that means I will have to give extra money and buy another hard disk) Since this system has both Windows XP and Linux on it and the MBR is altered before with easyBCD the Microsoft Experts!! at the shop tell me that they really do not know what to do !!!!! They say: we can only copy the Windows part with Acronis. The only thing I want is to copy this hard disk to another one and use it as before. Is seagate hard disk compatible with Ubuntu or what do you recommend me to buy I also want to buy a dvd writer(now I only have a cd reader) could you please recommend me a dvd writer that works out of the box for Ubuntu. If everything goes wrong I will definitely be NOT installing Windows again.I will only install Ubuntu.I do not want to go through those long steps again. So if the only operating system is going to be Ubuntu, then everything should work on this PC.That is why I am sensitive about choosing the hard disk and the dvd writer.
