stop baiting the poor windows person - don't you know MS encourages this sort of ignorance. B'sides, you know as well as I do that he is using the drive letters to refer to seperate hard drives rather than partitions ... in fact, it sounds like the primary master is entirely the original XP install and when the second drive was plugged in, he "installed it" to windows so windows called the whole thing D: ... this will be making Mandrivia behave oddly as windows will keep overwriting bits.
Windows does not play well with the other children.
(This may even be why he wants to get rid of mandrivia and return to the blissful windows
: Leaving aside why you would want to do something so insane as go back to windows ...
Here's a translation of your request ...
You have two Hard Drives installed in your computer.
IDE1 master = hda contains windows
IDE1 slave = hdb contains Mandrivia
You would like to no longer have mandrivia.
You would like to make IDE1 slave completely available to windows.
Step 1: get rid of the linux bootloader. Use the Windows recovery and type fixmbr (which is to fix
ecord. It won't actually do this, it's not broken, it will just write the windows bootloader in there.)
Step 2: use the standard windows method of installing a hard drive. If winodws already calls this drive D:, delete that drive. When you have the option to completely format the drive, do so. Bye-bye mandrivia.
And look how much you have learned already...
Good replies from the rest of you guys
