Remove Vista from an XP/Vista dual boot
Decided you don't want Vista, or perhaps you are ready to upgrade your XP, but don't want 2 copies of Vista on your computer. Here's how to remove Vista and it's new bootloader from your system.

not too difficult, simply load into XP and format the partition Vista is currently installed on. Since the Vista bootloader has control of the boot, there is no need to modify the boot.ini of XP.

Restart your computer with the XP cd in the drive, if you don't you will be prompted to pick an operating system. Once into setup, choose repair console.

A DOS prompt appears, and type the following:
*this will essentially separate XP and Vista

*this will check that Vista is no longer present and put the XP boot.ini loader back in place.

Restart and Vista is history.

This works!
I didn't realize Vista screwed with the boot sector so much, but when I deleted the partition Vista was on, I couldn't fix the boot option menu. This here works perfectly, although, I had to do it twice. The first time, I forgot to type in the last part of your command line. thanks!

Fix XP MBR and Partition Table
I will ask this question in a new thread since I havent really found a good answer from searching.

After having a dual boot system for a long time with Vista and XP, I decided that I was going to get rid of Vista and keep XP.

So, mistakenly, I deleted the Vista Partition on D:\ while in XP. (Confusion here because the xp partition refers to itself as D:\, but outside xp, XP partition is refered to as C:\ ?)

Before realizing something was amiss, I booted into XP repair console and did fixbmr, with no arguments. It spit out something that looked off, as in, the new drive is now device0/partition0. Didn't look right.

Then I did fixboot, also with no arguments.

Restarted, and there was no OS to boot into.

At this point I thought I lost everything, but I'm using UBCD to snoop around.
I reformatted the former VIsta partition into storage space for anything I could get off of the XP partition.

I found that all my files were still intact from XP, so I backed those up.

In short, I think i have no MBR or Partition table. I want my XP partition back to normal. Is there any easy way to do this with repair console or MBRwiz?
