Windows 7: Dual Boot Installation with Windows 7 and XP

Windows XP doesn't load when dual booting with Win7

I have used the W7 disc to repair so I can do a W7 boot at least.

Afterwards while in W7 I have found that the XP files are all on the new partition I made in W7. In fact, using bcdedit while in W7, I was able to get a bootladder that showed both W7 and XP when I did a restart. But when choosing XP it would never boot in to XP. It would just give me an error and freeze and i would have to do a repair with the W7 disc to start all over again.

Did this entire process a half dozen times, from the very first step to the last. Each time redoing each step anew.

I do believe that it would have worked if I would have installed XP first and then W7, but I didn't.

I believe this all has to do with the issue that XP never really really completes a full installation since it was unable to restart at the final stage. Wish I could just get that XP to restart after the install...Dang.

Any further thoughts or similiar problems or comments is appreciated.
I know this is an old question, but I had the same issue, looked everywhere and didn't see anyone saying that, despite the good tutorials about EasyBCD we can find:

In order to boot from the Windows 7 hard disk/partition, you must have NTDETECT.COM, NTLDR and BOOT.INI in Windows 7 partition, and that's the point: you MUST EDIT the boot.ini file that is in Windows 7 partition so that it points to the partition where Windows XP is installed!

When booting from Windows 7 hard disk and choosing Windows XP, bootmanager will look for those XP related files in 7 partition, and then will look for Windows XP where the boot.ini in Windows 7 partition tells it is installed. If you just copy boot.ini from XP partition to 7 partition without any changes, it will be like XP was installed in 7 partition and it will never load because it is just not there!

Edit boot.ini copied to 7 partition and change the rdisk number. There are plenty of tutorials explaing how to edit boot.ini file around if you don't know how to do it.

Do not change or edit original boot.ini or any system files in Windows XP partition, or, if in the future you want to load Windows XP from its own hard disk/partition (let's say you format or remove Win7 hard disk) you would not be able to do it anymore. Just let those as they are and edit boot.ini copied to Win7 partition.

Hope it helps someone.

I am running a dual boot of XP and 7 both 32 bit works good but I have 4 gigs of ram and 1 gig built into the memory card so it only uses 3 gigs I was wondering if a could dual boot xp 32 bit and 7 64 bit. If so would it be worth it for the extra gig of ram.

64-bit Windows 10 Pro

Hello Paul,

Yes, you could dual boot XP 32 bit and 7 64 bit if you would like to as long as you have a 64-bit supported CPU and 64-bit Windows 7 driver versions for all of your devices.

32-bit would normally use up to 3.25 out of your total RAM anyways. If you wanted to all 4GB, or more if added later, you would need to have 64-bit installed. For now though, I would not see you gaining much from going to 64-bit, but it will not hurt anything either other than having to reinstall it.

Hope this helps,

Windows 7 Home Pemium x32

Hey brink, thanks for the guide. I've encountered a little problem (I have no dualbooting experience):
I tried to install windows XP as I've done before, everything went well until the reboot after the disk format and file copy, when it loads the OS, it says: "Error loading operating system. Press ctrl+alt+del to restart" (which doesn't change anything). I had to use my windows 7 CD to restore booting settings to be able to use windows 7 again and post my message.
Also, I have Windows 7 Home Premium, so virtual XP isn't an option. And setting XP compatibility on executables didn't work either.
Any ideas?

Hello Dave, and welcome to Seven Forums.

Did you need to load SATA or RAID drivers during the start of the XP installation first?

Dual booting XP/7

Hey, actually, the message was: "A disk read error occured. Press ctrl....."

And how do i tell if i need to load SATA or RAID drivers first?
When I tried installing XP i just ignored the "Press F6if you need to ...." because I didn't know.

It depends on if you have a SATA (current standard with narrow cable) hard drive instead of IDE (older standard with wide ribbon cable), and if it is setup in RAID or not. If either one, then you will need to install the appropriate XP driver version for it during the XP installation first.

I'm quite sure I have a SATA drive (I dont see wide ribbon cable; I only see a narrow orange cable). As of if it is setup in RAID or not, I have no idea. Is there a way for me to find out? And where do I find the RAID drivers?? Sorry if I dont know a lot about this; never did it before.

Unless you manually setup RAID, then it isn't. It sounds like you will just need to install the XP version of your motherboard's SATA drivers during the installation of XP (F6). It will be the GIGABYTE SATA2 Preinstall driver (2nd one) under the SATA RAID section in the link below at Gigabyte.
