Windows 7: Dual Boot - XP Install Not Showing All Windows 7 Partitions

Dual Boot - XP Install Not Showing All Windows 7 Partitions

In trying to set up a dual boot system with Windows 7 and Window XP I have come across a very frustrating problem.

New system
HP Pavilion p7-1270t with Windows 7 installed

I have followed the instructions in SevenForums - Dual Boot Installation with Windows 7 and XP.

I shrunk my disk (in Win7) so now I have a Windows 7 partition and a XP Partition.
I did the slipstream so my SATA driver (Intel Express Chipset SATA AHCI Controller) was incorporated into the XP install (and I included SP3 after many different tries).

When I go to through the XP install and get to the select partition, I only see one partition, it is the entire size of the disk. I do not see any of the partitions that were created under Windows 7.

Any thoughts on what the problem is here?

Thanks,

Chips

Attached are the screens shots from what I am seeing.
Notice the XP Install sees the disk but no partitions.

Look in BIOS setup to see if you're using AHCI mode for SATA controller - if so you'll need those drivers for XP.

The XP CD with those drivers may be too old to see a 1tb HD's partitions, which normally requires a BIOS update which you obviously don't need since the HD is seen in Win7.

You can try again using an XP w/SP3 ISO and different drivers, but the hardware may have simply left XP behind.

Have you tried virtualizing which is becoming a best solution? VMWare, Virtual Player and Virtual Box are all good freeware choices.

If I can't figure out it soon, I may just go head with the XP install and wipe out the Win7 install. Then go back in and install Win7.

In that case you may have better luck with IDE mode if it's set to AHCI now in BIOS setup. You don't give up much.

Decided to throw another disk in the system and install XP on that disk but ran into another problem. When I choose that disk to perform the install, it wants to write some startup files on disk 0 (the Win7 disk) and it cannot because "this disk does not contain a windows xp-compatible partition".

I guess I can disable the the Win7 disk and install XP on the second disk but I wonder what will happen once I enable the disk. Sounds like the EasyBCD program will update the boot file and add the XP boot option to the disk?
Thoughts?

Always unplug the other HD during install to avoid these problems. Then after install plug back in the other HD, set preferred one to boot first in BIOS setup. When you want to boot the other OS HD, use the HP ESC one-time Boot Menu key to trigger it. This keeps the HD's independent to come and go as you please, and avoids problems that dual booting XP with modern OS's can cause.

Kind of found that out the hard way. Have everything setup and tried to use the EasyBCD program in Win7 to manage the boots, and now the system is in a constant reboot state after going through the Windows Boot Manager. I enter the Windows 7 option and it just reboots again.

If I can find a way to fix the boot manager than I will just use the HP boot manager as you suggested. Otherwise I just may end up trashing it and just install XP on the primary disk and be done with it.

Unplug XP HD, boot into Win7, in EasyBCD choose Edit OS Menu to Delete the XP entry.

Now plug back in the XP hd to see if you can boot it using BIOS Boot Menu. If not unplug Win7 HD and reinstall XP, deleting its partition to create and full format a new one.

If Easy malfunctions in Win7 and it continues to boot loop at start, unplug XP HD, boot into DVD to run Startup Repair a few times after making sure Win7 or it's 100mb SysReserved partition is marked Active: Partition - Mark as Active.
