Problem copying winXP partition to a new HD

I have a 60 GB HD with three primary partitions with Win98SE, WinXP Pro SP2, Win 2000 Pro

and a extended partion, all in FAT32.

I launch the three OS with BootMagic.

Two weeks ago I copied the four partitions in a new 200 GB HD with Partion Magic 8.00,

increasing their size.

After this, I set the new HD as Master Disk, and the old HD as Slave, for testing the new

partitons before formatting the old HD.

After this period, yesterday I tried to disconnect the old disk, and while Win98SE runs

well, launching Win XP I saw, with an heart attack, a black screen with a long message about

a "missing OS". I have an another problem with win2000, but it is not important because I

can format it.

Lookig at WinXP Boot.ini, I saw these lines:

[boot loader]

timeout =10

default =multi(0)disk(0)rdisk(1)partition(2)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(1)partition(2)\WINDOWS="Microsoft Windows XP Professional"

/noexecute=optin /fastdetect

I thought that rdisk(1) aimed to the slave disk,

so I changed the word rdisk(1) to rdisk(0).

After this change WinXP starts, I can see the log in screen with the list of Users, I try to

write the administrator password, I see the message "connecting...." but after few seconds I

see the message "disconneting" and the OS shows again the same log in screen with the list of

users, without any other error message, and I cannot enter in the OS.

With a Dos boot floppy disk I have changed again rdisk(0) to rdisk(1) and I have reconnected the

old HD, but I don't know what to do now for using only the new disk, formatting the old one.

Can anyone help me ?

Excuse me for my poor English.
