Windows 7: Adding a 5th partition

Hello Vincenzo.


It's perfectly safe and very easy to convert the Windows partition to an Extended partition and shrink that to create as many Logical drives as there are available drive letters; if you convert one of the OEM 'tools' partitions you may lose functionality.


Have a look at Method Two of this tutorial at the link below.

Partition / Extended : Logical Drives



Whatever you do, do not convert the disk to Dynamic.

This is the way I would recommend.

If you really want the F8 option - it can be added afterwards.

Any partition changes may affect the normal access to the oem recovery app. - depending how it is set up. Usually can be reinstated also. Your friend should have already run off the oem recovery discs - just in case he wants to return to factory state at any time in the future.

1) Move the Win7 boot loader files into the "C" partition. You can install EasyBCD from NeoSmart Technologies and it has a menu item to do this for you.
2) Reboot to confirm that the migration of boot loader files worked
3) Using the Disk Management utility, remove the small System Reserved partition. Reboot to confirm this was OK
4) Using the Disk Management utility, shrink the Win7 "C" partition to make some room; reboot afterward to confirm this was OK.
5) Add a new Extended partition into the unallocated space, and create Logical partitions inside that.
I assume he has good reasons for wanting another partition - keeping his data separate from the o/s for example . That does make any housekeeping, imaging , restoring, etc vastly simpler.

OK, thanks to all for the help. I expect to be working on this over the weekend.

Knowing my friend as I do, I think he may want to consider an option that does not involve changing the C partition from primary to logical, so I'd like to have another option to offer to him.

If he decides he can live without the HP Tools partition, is there any problem with deleting it? This will allow creation of another primary partition, which can be created from space gained by shrinking the C partition. Are there any downsides to this approach? I guess I can image the partition before deletion in case there is a problem.

Thanks

Hello again Vincenzo.



Just so you will know and not be surprised; if there are already 4 Primary partitions and you use Windows disk management to delete one of them and create another to take its place, it will be an Extended partition by default and not another Primary, which is just as good, if not better as you can create as many Logical drives within the Extended as there are available drive letters.

It is possible to use Windows diskpart to create a fourth Primary, just ask and I'm sure someone will help with that if need be.


The really wise thing to do would be to create an image of the entire Hard Disk Drive, with all the factory partitions intact, especially if he ever intends to need to use the factory recovery option.

As to making the "C" partition logical -- you can only do that if the BOOT partition is elsewhere. IF you move the bootloader files into "C", to free up a partition, you have to leave "C" as Primary. Why? Because (AFAIK), Win7 requires its boot partition to be Active, which in turn, requires it to be Primary.

There is nothing magical about a logical C partition. As long as you have the 100MB active partition, that will work. Deleting the HP tools partition may have downsides. If I were you, I would investigate that first. Turning the tools partition into a logical would be my next choice (after C as logical).
