how can i partition my laptop in windows vista(dell laptop) with out formatting  

once again ask ur customer about it ..im helpless

hi,
you can do partition in your laptop with out formatting it, by using a third party partition application. Like linux partition application. I forgot the specific name of the linux partition but it did work, for me. Hint: you can search it in google, or bing and etc.

just type in cmd
format: C

C is your hardrive you can change it//

I think it is not only you but many who are using a Dell laptop are facing a similar problem. I read about this news in many forums. I think it is better you contact the customer support of Dell for further assistance.

You can easily do that. Use third party toll partition magic. Just remember that you should have high amount of power backup.

Yup, a program called partition magic is a tool for partition without going to dos prompt. Another thing you can consider is creating a virtual drive. I have one like this in my dell laptop. I create a virtual drive with a window xp Os. But consider you have a high memory to be able to handle the massive memory eaten by virtual drives. Hope it helps you.

go to my computer and click right button click on manage after clicking screen will appear click on the device management there you find your all hard drive there you can partition it without format.

If you are a Linux user just delete & re-create the partition using GParted, everything gets solved, unfortunately IF you are a windows user GParted is not available to Windows, so you could try some other softwares (idk names of any windows soft).
