Help with Dual Boot please - Windows7 and XP

Hi there

Hope u can help me. But before I go on, I have searched high and low and can't find the answer to my question anywhere here. Hecne why I am starting a new thread:

I have a PC, with 2 hard drives: Primary HDD, 250Mb, and a secondary drive, 1Tb.

The primary is labelled as 'C''Windows 7'. I have partitioned the secondary drive, into 2 drives: D and E. Called 'D' Windows XP and E my Games drive. D again is about 250Mb and E the rest.

I then proceeded to install windows XP 64bit over my windows 7 64bit. Followed the tutorial here and it all went ok. I have the XP installed, operating fine and my 7 is also working fine. However, I can't get the dual boot display to work correctly at the moment. To boot into XP, I have to hit F12 during boot up and select my second hard drive to boot up. and if I want 7, it boots up by default.

I have modified my BCD registry per tutorial, both in XP and windows7. I get the dual boot message at the beginnig, but when I click on XP, it tells me boot.ini is not correct, failed to detect NTLDR.

Can someone please help me and tell me what to do.
One thing I have noticed is that when 7 loads up, the drives are as they are. But when XP loads up, it renames my C drive to D and my D drive to C. So even though 7 is installed on C drive, when loading XP, it says C is the XP drive! Wierd!

PLease see the attached screnshots. They are pretty much self explanatory, they where all taken with 7 loaded up and not XP.

I woulds appreciate the help in trying to sort my dual boot out.

Thanks very much.

The cleanest dual boot method with separate HD's is via BIOS boot order, or one-time Boot Menu key. This makes HD's independent to come and go as you please, whereas Windows-managed dual boot interlocks them.

If you want to use BIOS boot method, then just Remove XP from windows-managed Dual Boot using EasyBCD, set your preferred HD to boot first in BIOS boot order, then use one-time Boot Menu key to boot other drive.

If you still want Windows-managed Dual Boot, Install EasyBCD 2.0 beta to Windows 7 after doing quick registration to use beta in forum.

Remove XP listing on Add/Remove tab, then add it back, accept boot files, autoconfigures, Save, Restart.

Let us know how it goes.

Whats one time boot menu? Is it something setup in Bios?

Currently I can only use the bios method to boot. As said, have to press F12 to give me boot options. Then choose HDD and select the XP one. I do like to use the windows one if it is more staightforward than the one time boot.

Any help on one time boot appreciated.

Looks like it's F12. Is that satsifactory for you to use for XP, along with presetting Windows 7 as first to boot?

If so, does the existing failed attempt at WIndows-managed Dual Boot menu interfere or appear along the way to booting either of these via BIOS?

Only if so should you try removing the WIndows-managed XP entry using EasyBCD in Windows 7.

Unless you do in fact want as Windows-managed Dual Boot instead. Do you?

Hi Nariman,

You see ntldr, boot.ini and ntdetect.com on the XP partition - just copy and paste all 3 onto your windows 7 partition.

Change easybcd entry for XP to point at drive C.

Should take about 10 seconds.

Hitting F12 is a bit of pain, as sometimes if I forget to hit it, then I have to retstart and start from scratch.

Now I need to find the drivers for the 64bit windows XP!
