manually edit xp's boot.ini file to select win 7

i was dual booting Windows 7 and xp and then i formatted my xp partition,installed a fresh copy of xp and now it automatically loads windows xp, it doesn't show where i use to select the OS to load

my disk is partitioned c drive for Windows 7 and d drive for win xp

this is the contents of my xp's boot.ini file:

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

how do i manually add Windows 7 to the boot.ini file of win xp so i can select Windows 7 to boot?

It needs to be done the other way round.

You need to reinstate Windows 7 boofiles, then add the (XP) ntldr to Win 7 bcd.

See step 7 onward of this tutorial:

Dual Boot Installation with Windows 7 and XP

Hope it helps

windows 7 ultimate 64 rc 7100

Hi I have a similar problem, but it occurred in a differnet way.

I had XP installed on one disk, with another disk for data.

I then wiped the other disk, disconnected the xp disk and installed 7 on the now empty disk.

If I connect back up the XP disk, it always boots into XP, unless I go into the bootload screen for my MOBO, and select the 7 disk to boot from.

How can I get the bootload screen options in this case please?
