Deleted active partition XP not booting

Specs: Windows XP, 1 gig
Logical partition is still there and is where
windows is installed, but the active partition was
deleted. Won't boot. How can I make the
partition with windows again active with just a
bootable cd?

How do I go about doing a repair install? And do any of the boot
programs work off of CD's? My main problem is this computer
doesn't have a floppy. Thank you all for the fast responses I appreciate it greatly :). I think I deleted the boot files cause they were on the active and just pointed to the logical partition.

"Logical partition is still there and is where
windows is installed"

That cannot be right. You can't install Windows on a logical partition. It has to be installed on a primary partition and then made 'active' (Windows Setup makes it active by default).

If the active partition has been deleted you'll have to re-install Windows or try this:

I don't know of any free partition recovery software that can recover a Windows partition 'cos most of them only work from within Windows to recover non-OS partitions.

Actually you can. This then becomes the boot partition,

What has to go onto a primary partition is the boot files, NTLDR, Ntdetect.com and boot.ini. This then becomes the system partition,

When you deleted the primary partition all the boot files went with it. I don't think you can convert a logical partition into a primary partition so you need to create another primary partition.

What you might try is once you have a primary partition boot from your Windows CD and go into the recovery console and type FixBoot. The boot files may well be copied and a correct boot.ini file created to allow you to boot the exiting Windows installation.

There are plenty of partitions managers that will recover deleted partitions from outside Windows. In fact you a restricted as to what you can do with partitions from within Windows as Windows tries to protect itself.

Test Disk is one to try.

Any win98/me boot disk will do what you want. You would start fdisk, create a primary partition, mark it active and then exit. You would then format as bootable.

To recover the windows boot you will need to do a repair install of xp since fixboot does not copy files. It only reinitializes the volume pointer.

You could shortcut this after format by coping the boot files from another system. You would need to run fixboot and fixmbr to get them to work.

That's the name of the software I used to try to combine the
partition XP was on and the partition my old installation was on.
The old installation partition was the active and when they were
combined I think I lost my boot table.

That is not what I am asking. What is the MAKE of this computer? Did you built it yourself or did you buy it from a store? Is it OEM like Dell, HP, Sony, Compaq etc etc?

If no floppy drive your only choice is via cdrom boot.

This being the case set your bios to boot the cdrom first and using your xp cd partition and format the c: partition.

I would then exit and reboot to do the repair install of xp

A repair install does not delete data. I have found I had to reinstall some apps but that was all.

But considering how your endeavor has gone I would suggest backing up your data before you do anything else.

What ever you do do not delete any partitions.

To begin with ... How did you installed XP? Did you do it yourself using retail XP installation CD, or did it come preinstalled with the HP machine you purchased?

"partition XP was on and the partition my old installation was on. "

Whoa! You combined the boot and system partitions? Did you do this because of a lack of disk space?

Did you run chkdsk /f?
Did you run disk cleanup and then defragged the drives?

What makes you think the 2nd partition is still there? It should not be.

Having seen this scenerio before I am suspecting your disk was trashed as well as what you had on the 2nd partition.

You should find a local computer shop that is experienced in partition recovery.

I second wanderer's thought.

This website has hundreds of posts asking for help to reverse what Partition Magic has done. The consensus among experienced users is that Partition magic is a fantastic tool for those who knows what they are doing.. and a bomb for those who don't..

I was doing this for a friend..let me explain in detail what
happened. His computer was riddled with viruses and would
not boot. It was a standard HP partition setup..recovery
partition and then the user one. I didn't have a flash drive
available so I installed windows on the recovery partition and
booted into that. I then copied all of his files over and then
deleted the larger partition in which the OLD windows was
installed with partition magic. This OLD partition was deemed
the active, so I erased it and had it set to combine with the
LOGICAL=new xp installation. I read a message about
needing to set a new partition as active but I completely forgot
and let it do its thing. SO I'm pretty sure it's still there..it just
doesn't have a boot table. Does this make sense?

You should have converted the logical to a primary first.

You can try booting up on the xp cd and if a windows install if found then you are right everything may still be there. if no windows install found then everything is trashed and you might as well do a new install.

Google xp repair install for the how to.

You're right, I just checked. However, it's not a straightforward procedure. Oh well, just goes to show you can never stop learning! My apologies.

That question has already been answered. Repairs keeps documents and folders int.

Don't worry about making the partition active. There was a time that there could only be one active primary partition on a hard disk, hence the need for Extended partitions and logical drives.

However that is no longer the case. All primary partitions are active by default now.

Ben how about a little self help here?

I already told you that to repair the boot you need to do a repair xp install. I already told you your files are fine with a repair install [they are not with a new install so you don't want to do that]

Google booting cdrom via the bios
Google xp repair install

You say xp sees it but I don't know how you are coming to that conclusion if you don't know how to start the xp repair install.

Last I heard only one primary partition can be active at a time.

I have two hard disk on this machine with two primary partitions on each. All four are being used and not an Extended partition or logical drive in sight.

The concept of active partitions is really a throw back to DOS where DOS could get confused if it found two primary partitions on a hard disk. Modern boot loaders go about it a slightly different way. Fdisk will still only allow one primary partition on a physical disk.

... quite right "StuartS" you can have many primary partitions but the one you boot to should be active for it to work!

... there is a file in "pm8" called pqboot(32) that will make the partition active either in dos or win32 mode.

Not to digress but you can have 4 primary partitions per disk or three primaries and an extended partition with logical drives [limited to 23 letters]. The active bit is not a holdover from Dos since it was a requirement in other OS's also. If you go into disk management you will note only one primary is marked as active per disk [may not be active on the 2nd disk]

BenThomas how are you "seeing" the xp partition?

XP repair won't work it doesn't detect it as a windows partition.
On the other hand, Norton Bootmagic allowed me to set it as a
primary and change it to the active. It's now detected, but all I
get is a gray blinking bar. Progress?

Norton also acknowledged there was about 3 gigs used on the partition..which is about what there was. So it is still there.

BenThomas your disk is trashed. 3gigs isn't enough for OS and programs let alone your data.
If you have any hope of recovery you need to take it to a recovery expert.
Or bite the bullet and reinstall a fresh xp.
