Windows XP 32 + Windows 7

Hi, after auto-entry, win7 loads fine but XP always gets black screen and resets without giving an error.

First of all, can some one tell me clearly what is disk(a) and what is rdisk(b) and what is multi(c)? I googled 348738 pages and no one answers these clearly. We will always mess up with the drive letters and stuff if somebody doesnt explain about it.

Below is the set up:

1st system : Win XP 32 on SATA when C:SATA, D:none (SSD removed)
2nd system: Windows 7 on SSD when C:SSD, D:none G:SSD

installed EasyBCD 2.0 on Windows 7.

I though Win7 boot sees my ancient xp64 on its boot.ini, which had already been removed. so I tried copying boot files (boot.ini + ntldr + ndetect) from XP to Win7. But nothing changed.

By the way, I was told that win 7 automatically see and load winXP if I install XP first, but it did not care.

Note: SSD: Win7 (Running) + Win64(deleted) and SATA: winXP32 (running)

waiting soon..

Does your W7 Installation have a 100Mb unlettered "system" partition ?
If so, give it a letter, delete the XP entry, add it again, let EasyBCD auto-configure, don't change the letter it assigns XP.

If not, post Disk Management and "display settings" info as detailed at the end of the sticky thread.
Auto config did not work, and there are no extra partitions, just 2 bare HDs, SATA and SSD, as whole, in other words, 2 HDs and 2 partitions and 2 systems we are talking about.

I had to GUESS what disk, rdisk, and other stuff means and played with the boot ini and some documents and SUCCEEDED. For example, edited the boot loader like this:

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

Thanks for your reply anyway.

That boot.ini is wrong.
Default and OS lines should contain the same information for a single copy of XP.
Whichever one works (the one you select or the one that boots if you don't select anything (default)) should be copied to the other.
(rdisk 0 is the disk you have put top of the boot sequence in the BIOS, rdisk 1 is the other - It can't be on both of them)

That boot.ini is not one created by EasyBCD. In what way did the auto-configure fail ?

Hello there,
You will need to check your boot.ini.
