Windows 7: Dual booting question.

This is not going to end well. The best I can suggest is that you stop. Installing Windows XP after you installed Windows 7 is possible, however, a major pain. You hard drive is not setup for Dual booting and it would be best to start with a clean slate. Like removing that 10 GB OEM partition at the front.

I have my computer to dual boot between Windows 7 and Windows XP, what I do is manually setup the partitions prior to installing. 100 MB Primary Partition (System Reserved, holds boot information), Extended Partition spans the rest of the drive. An Extended Partition holds Logical Partitions which the OSes install to. One for Windows 7 (The biggest and at the front), the next for Windows XP.

For best results---and ease---it is advised to install Windows XP first.

I don't really feel like reformatting my computer just to dual boot. I'd have to get back everything I have downloaded and all the modifications I did. Removing that 10GB OEM partition might void my laptop's warranty so I'm afraid of removing that as well. You said that you installed your OS on logical partitions. Can't I just do the same by creating a new logical partition via partition wizard? Or would it cause problems :O I was thinking about creating a new logical partition via partition wizard and then converting it back to primary then install Windows XP on that. Would that cause any problems?

Did you try creating the Partition with Partition Wizard? It will often allow the fourth Primary partition when Disk Mgmt won't.

XP won't install to Logical because it installs the System MBR and takes over the boot until Win7 is added back using EasyBCD 2.0. System MBR cannot be written to Logical. If you were installing Win7 last it would update the XP MBR so it could be installed to Logical.

You are entitled to run four Primary partitions so try Partition Wizard as it should allow it. If not, try Paragon Partition Manager free version.

Actually, Windows XP can be installed in a Logical Partition. You only need an Active (boot) Partition that is a Primary Partition. Ie., the System Reserved Partition.

I've not installed XP to a Logical partition after Win7 install but wonder if it will write its boot files to the 100mb System Reserved active partition, since when XP is normally installed after Win7 it takes the System MBR into its own partition until EasyBCD 2.0 writes it back to the Win7 System partition.

But worth a try nonetheless to see if the boot issues can be dealt with pro-actively.

Does the OP have a Win7 installer to clean reinstall even if he wanted to? If Recovery Disks can be made which give a path back to factory install, would you consider wiping the HD to do a clean install Dual Boot XP then Win7?

When installing Windows XP or 7, it automatically writes the boot code to the Active Partition, no intervention required.

@gregrocker, Yes I did try creating the fourth primary partition via partition wizard but it won't let me. I also just tried to create it as a logical first then convert it but when I try to convert it, the program doesn't let me. Paragon Partition Manager personal is not free (I have 64-bit). Any other suggestions?

I think LogicEarth's solution to try XP install to Logical partition is worth a try.

It may place the XP boot files on the current 100mb System partition.

If it fails, then try converting the Logical partition to Primary as you proposed.

First double check that your 100mb System partition is marked Active as it does not show on the Disk mgmt screenshots. If not, use PW to Modify>Set to Active to be safe.

Actually, I'm just going to not bother. I don't want to go through so much trouble. Thanks for all your help so far though. :-)

Sorry we couldn't be more help.

You might want to look into running XP virtually as some find that is all they need.
