hmm, so at the moment the C and D drives are used as Masters? So took out? and the E drive is always in?
Well, first of all, you need to go about installing windows on the E drive, now this is not possible without losing data since it ends up formatting it. Back up all the data you need onto cd or an external mp3 player or something and then re-install windows using the windows disc.
After that is done, connect the other two drives as Slaves to the E drive (master with windows now on). You might get a boot order, so select the one you know is E.
now the easiest way to fix this would be to then back up data from these two drives (since they equal a smaller amount than the biggest drive E) and then format these within windows:
Right click my computer, and go to Manage.
Select disk management from the list and then right click and format the other two drives.
Then you'd now have 2 blank drives in which you can copy the data back (make sure its only backup data though, and not programs and such which you could just re-install)
If you don't want to do that, I'm afraid i have no other way, unless you keep Windows on those two drives, but stop them from booting up at the start by changing the boot order.
If this is the case, go to Start, Settings, Control panel and click System.
Now go to Advanced tab, and then to Settings unde Startup and Recovery.
Now press Edit, next to changing the boot options.
It should be something like this after re-installing on the E drive:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Drive E" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(2)partition(1)\WINDOWS="Drive C" /fastdetect
multi(0)disk(0)rdisk(3)partition(1)\WINDOWS="Drive D" /fastdetect
*Boot order might be different so you might have to double check*
*Rdisc means a seperate drive, while partition 1 means windows is installed in the first partition of that drive (standard)*
*After the timeout, the one labelled below it is the one that will boot, in this example, rdisc 1, or the drive E*
Just delete drive C's and D's parts to this so when windows boots, it doesn't see the other two drives as having windows, so you just have this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Drive E" /fastdetect /NoExecute=OptIn
It will now stop coming up *Drive E by the way isn't what it'll say, its more likely to say "Windows XP Professional" if this is what your using, so make sure before you delete, you know which are which. One way of checking this would be to change the names in the brackets, restart and then test which one it is
*.
Then just go to File, Save
I hope this helps
