Hi

Yesterday, after sinking the local disk, I accidentally install ubuntu on the same partitions as vista.

I want to uninstall the ubuntu part. I am new with ubuntu, so anyone have any solution for my situation.

Thanks

Almost certainly if you installed ubuntu (or any other OS) over Vista, then Vista is gone for good. You *might* be able to salvage some data with testdisk.

In my case, I can boot by both vista and ubuntu. The only thing that doesn't seem right it that I sink 160GB to 104GB so that I can use the free space for ubuntu. However, right now, both ubuntu and vista show me that the "my computer" for both system is 104 GB.

Well then, show us the contents of
fdisk -l for starters
and we'll sort it out

Actually, can you tell more about "show us the contents of fdisk -l". Is this a code for ubuntu terminal?

Yes, for any Linux terminal....In Ubuntu, you need to add "sudo".

So, open a terminal window and enter "sudo fdisk -l" (no quotes, and it's an ell, not a one)

Yeah, the code works. In first, I didn't use the word "sudo" because I assumed that I can use syntax in unix in ubuntu.

You could proceed in a number of ways.

You could boot into Vista and use it to remove the Linux partitions. You can look under Control Panel then Administrative Tools and Computer Management then Disk Management. (at least that's what it's like in XP, I assume it is similar in Vista) After that, I'm not sure whether Vista will let you extend your existing partition back into the unused space.

In ubuntu, you could type sudo fdisk /dev/sda. The program is menu driven and will allow you to delete the partitions all too easily, so be very careful. Try typing man fdisk to read the instructions first. Then this tutorial should help: http://www.howtogeek.com/howto/windo...sta-partition/
