Hi,

bad idea to use Windows to rework disks with other system if it is what you have done (what is not clear for me). Right this is not an answer. But your request is not a question. Can we help you? we can try.

You are speaking of two drives ... in a laptop. So you've got two physical drives? Or do you speak of partitions of only one physical drive?

My guess is you better but your live CD of Ubuntu and try another install.

No, i am talking about the partitions of a single physical drive. in my laptop i have 4 partitions ( C,D,E,F and G) of my hard disk. in one disk i have windows vista ( as installed originally in one partion "C"). last month i have installed Ubantu 8.10 in another partition 'D'.
Now i want to unstall Ubantu so that i can see and use that partition and available space in windows. please advise how i can unstall or format the partition in which i have installed Ubantu.

You will need to rewrite the MBR record for your hard drive. If you don't know how to do that, I would suggest reinstalling Ubuntu to your 2nd drive ("D:") Be careful not to erase the first drive/ partition, probably declared /dev/sda1 or /dev/hda1.

Once you have Ubuntu working and able to boot both Ubuntu and Windows, then run a Windows command called fixmbr.exe This will overwrite the master boot record (MBR) with the Windows version and it will basically ignore the Ubuntu install.

The reason why what you did didn't work is because the Grub boot loader actually reads its configuration from the 2nd drive. When you reformated that 2nd hard drive you blew away the configuration file for grub and now it doesn't know how to boot either Windows or Ubuntu.

Can you help with this problem?
