Solved undo Dynamic disc conversion

December 12, 2012 at 21:21:39
Specs: Windows 7

just did a fresh recovery on my daughters HP laptop cause she completely trashes it regularly.
anyhow i decided to partition a section of the drive for her to store her files and make re-installs a little quicker and easier.
in disk management i shrunk the os volume, and went thru the steps to set up the new space, i wont go into a lotta detail here because i know you guys know what im talking about.
apparently i changed the disk to dynamic (i saw the warning but still clicked to proceed, i usually learn everything the hard way about things i dont know).
after doing some research i know what the problem is, i just want to switch everything back to basic.
the machine has a recovery partition from HP, and the windows 199meg partition for its top secret stuff (boot stuff i think), there is an HP Tools partition, and the os partition. i have already deleted the 5th one that i created, apparently 5 is the magic number for partitions on a disk and forcing to dynamic.
as it stands now the computer will not boot to the recovery partition, i was just going to reinstall again to solve the problem. normally i wouldnt care much cause on my computers i make my own recovery partitions and install all the time when ive gone too far but her computer still has the factory recovery and i dont want to lose it.
all i want to do is undo what ive done and not lose factory data. i have several hard drives around here and a few computers to use should i need to in order to get it done.
before doing anything i want to clone her recovery data and store it on one of my drives for safe keeping, from there i want to undo my goofup.
any and all help will be appreciated greatly.

Data loss will happen during the conversion back so you MUST get the data first. Here is everything you need to know about basic vs dynamic and consequences of switching.

I would remove the drive and use a free program like recuva or Pc Inspector to recover your data on another computer that you can get the operating system to load on. By installing the hard drive as a slave in another unit, you can simply copy over files but I find recovery programs best. You can use something like Macrium reflect to make an image of the recovery partition, but I doubt you will get much use from it. All you need is the windows license sticker, an operating system cd and the drivers can be downloaded again from HP.

✔ Best Answer

Some Partition Manager softwrare will do this (for example Paragon Partition Manager Professional). Google "convert dynamic to basic" to find more.

You can NOT have more than 4 primary partitions. Unfortunately HP regularly configures the HDD with 4 primaries, so that means you need to make some changes before any new partitions can be created.

What I have done in the past is create a complete set of Recovery discs, then delete both the Recovery partition & the HP Tools partition. That leaves the 200MB 'hidden' partition, the OS partition, & unallocated space. The rest is easy.

I use EASEUS Partition Master Home Edition which is free.

If the recovery partition is already trashed, you can either purchase from HP a recovery disk set and use that to restore the system (at least the OS partition) or keep it for future need. If you have a good disk image that you can restore to, order the recovery disk set for future protection, delete all partitions, create what you really want, and restore the system drive from your image. As long as you have a disk image stored in a safe place (a hard disk and possibly a spare on a couple of DVD's), you really do not need the recovery partition.

You have to be a little bit crazy to keep you from going insane.

if i create an image, when i use it, would it convert to dynamic again? or does that part not matter. what im thinking i should try is clone the entire drive then wipe the original drive and convert back to basic, then copy the clone to it. is that possible?

ty all for the replies and help

well i finally got it, i was just one click away from wiping the entire drive and i decided to give it one more shot.
creating a system image was a fail; immediately after the image was complete (i had it written to another hard drive) windows said it couldnt find a system image at all. i was planning to create images of the partitions and then revert the drive back to basic and then try to apply the images back to the hdd. was a nogo for sure.
what i ended up doing was pulling the hdd out and connected it to my computer, went to disk management and converted back to basic; that left me no partitions and the drive just showed as unallocated space. from there i used EaseUS Partition Master (free home version) to recover the 4 HP partitions. Then i put the hdd back into the laptop and attempted to boot, it wouldnt boot so i popped a windows 7 disk in to attempt to repair the boot sector. HP recovery picked it up from there so i just hit the "restore to factory condition" and walked away.
I got lucky to say the least.
ty all for the replies and help.
take care and merry xmas

o and a microsoft rant, something that can be nearly impossible to undo, should not be able to be done with one mouseclick. i did skim thru the microsoft help forums and found nothing at all useful. all a buncha copy/paste crap that pretty much says nothing. they should step it up a bit because while this is my first time asking for help here; i have fixed many many issues and learned a lot from this forum, and have never found anything i could use at microsofts site. anyhow cya guys and ty for all the information in these forums.
