Yes you can install XP onto the Logical.

You can have four Primary partitions or three Primary and unlimited adjoining Logical partitions.

During the install the XP bootloader will be installed which doesn't know about 7 or vista so you will have to use EasyBCD restore the Vista/7 bootloader. It sounds like you have things under control but I suggest a backup.

Easiest is to restart Win7 by confirming 100mb System Reserved partition is marked Active: Mark Partition Active,
then run Startup Repair - Run 3 Separate Times.

Once Win7 starts, install EasyBCD to add XP on the Add OS Entry tab.

If there is no data on the Extended/Logical that needs saved ...


Use Method One listed in the tutorial linked below to convert the Extended to a Primary.

Partition / Extended : Logical Drives

diskpart

list disk

select disk # = disk number

list partition

select partition # = partition number

delete partition

create partition primary

You will be using it on XP to get back 7. When you are done with the install you won't see an entry for 7 because now you are using the XP bootloader which doesn't know about 7. That is why it is preferable to install the oldest OS first. Therefore you are using easybcd to recover the 7 bootloader. Then you have to make sure that you have entries for both OSs. It is tricky to do. Also you need to consider whether or not your system have XP drivers because XP IMO is fairly useless without.

Bare Foot Kid, those directions on that page are confusing. do i have to absolutely need it? and if i install it all and im missing drivers n what not, will i still be able to get to the xp desktop? and use easybcd to get back to 7?

Looks like i messed up my computer. i found a usb hdd i had, thought i could install xp onto that instead of making partitions and it wouldnt mess up the mbr because it was on a completely different hard drive but i guess i was wrong. halfway through the setup of xp on that usb hdd i get a bsod (after it says it needs to restart for the first time), now whenever i try to start it up i guess its trying to start xp boot instead of windows 7 boot. help! ive tried putting in my acer recovery disc which there is no startup repair on that, i also tried my windows 7 disc and i still dont see startup repaid on that. help me! what should i do?

when i start it up with the usb hdd plugged in i get a bsod, when i take it out it says windows couldnt start because "computer disk hardware configuration problem, could not read from the selected boot disk"

i still have the 50gb partition on my laptop harddrive, if i install another windows 7 onto that, will it fix the mbr so i can get back to my original windows 7?

and since im havin problems with xp, and since i need a 32 bit, after i clean this all up can i just install the windows 8 beta onto a partition and not have any problems with the mbr? thanks
