how to change a logical drive to a primary dr

Specs: Windows XP

I have WinXP installed on a logical drive, I want to keep this installation but change it to a primary drive by any trick posssible.

Tried to create a partition image but it forces me to restore onto unallocated space which it automatically designates as logical yet again !

You can't do that. logical partitions are part of an extended partition. You can only have a max. of 4 primary partitions or 3 primary and and extended with as many logical partitions as available letters and space.

Why do you feel you need to change it?

You would need to delete the logical drive and extended partition and recreate. Assuming you can follow the above parameters.

You could clone or image the partition somewhere and then rework your partitions and restore back to a new primary partition. Trouble is the drive letter will be changed causing many problems.

If you feel you must do that, then start over. Also, changing one partition will affect others. If programs that run under Windows are installed to other partitions you may have issues with them too.

Thanks for your answer.
Just discovered that Partition Magic does it with 1 click and a 5 second delay !
I've also found a rather confusing manual method.
All worked great until I deleted the current C drive through which my logical drive was booting. That killed it BUT repositioning the partition to the very start of the hdd using the Partition Manager in Spotmau allowed it to partly boot, i.e. the WinXP logo appeared but it then keeps going straight into shut down, restart etc and safe mode will not boot. ANY GOOD IDEAS ABOUT NEXT STEP PLEASE ?

You could try a repair installation but I think you are going to have more problems than it is worth.

I asked why you needed to make that a primary partition but you didn't answer.

It's my brother's business laptop and has some useful progs he would like to save.

Somehow he managed to get the whole set up mangled into a non standard mess.

My task is to save the day.

Still doesn't explain the need to convert a logical drive to a primary partition.

The primary partition was unbootable as it was partly corrupted but was nevertheless required to exist in order to boot the installation on the logical drive.

As this laptop was 2nd hand with an ex network set up I could not use normal recovery methods.

So, as a logical drive on it's own is unbootable, I needed to convert it to a primary drive and add all the other boot config files and hope for the best.

As you realized it was a mistake to convert logical to primary.

The OS registry entries [4000+] wouldn't match with the change. Might boot but wouldn't load. End result is a bigger mess. Changing a partition always has dire consequences if you don't think about the upstream consequences.

Proper procedure is to restore the primary partition booting.

run recovery console [boot theOS cd/dvd via the bios]
execute the commands fixmbr and fixboot
exit
reboot.
does it boot?

if not then as suggested by Othehill a repair install is in order.

But the first rule of recovery is back it up. You should have imaged the drive before you started changing partitions. Even PM tells you that on the screen :)

At this state recovery is pretty minimal. I would try putting back the primary partition [trick will be getting it physically in front of the now converted logical to primary back to logical partition] back. Then do a repair install. End result is you have to redo all the service pacs but you are up runinng with your data and programs.
