Can a basic boot disk be converted to dynamic and then spanned?

Q: Can a basic boot disk be converted to dynamic and then spanned?

Is it possible to create spanned dynamic disks when one is the boot disk? I am getting conflicting info.
I have two 120GB SSDs and one is the boot drive and it is at 92% capacity, while the other is empty.
Problem is the empty is a dynamic and the boot is a basic. I have read that a boot disk cannot be spanned and to compound the problem I have to convert it first to a dynamic disk. I am running Win 7 Pro 64 bit. Is it better to just by a bigger drive?

Preferred Solution: Can a basic boot disk be converted to dynamic and then spanned?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Can a basic boot disk be converted to dynamic and then spanned?

A spanned volume cannot be used for either the boot or system volumes. They can only be used for a data volume. The problem is that a spanned volume cannot be accessed until the drivers are loaded and the drivers cannot be loaded until the volume is accessible. For that reason Windows won't allow it.

Hello All,

So I was trying to extend a HDD and a popup appeared about the disk becoming dynamic I thought it was referring to the free space disk, meaning the the free space disk would first become dynamic then it would be extended on the HDD. But no it converted the whole HDD to dynamic!

Now windows loads everything OK. The drive this occurred on is the data drive which stores all programs (most of them, not OS, OS in on SSD) and users data. All data is backed up. However I really do not wish to backup and restore would be a big hassle. Any way to convert back to basic without losing data?

Saying that what is the consequences of making the disk dynamic? (I mean if no difference from basic I could just leave it).

hey there,
upon changing desktop computer and moving all the hard drives from one to another, my friend clicked on convert to basic instead of simply activating hard drive in computer mangement... the disk is basic now with 1 partition instead of previous 2 extended logical partitions and all data were lost.

upon researching, tried some recovery softwares but with no luck, i was directed to use partitionguru (diskgenius previously) and upon partition recovery, its showing me the "lost partition" with all the file and folders as they were, which is good, but its not showing a fully used volume as it was


now i know that previously the partition was an extended partition, so originally the volume had one drive letter with 2 partitions in it.

2 questions i would like some help with if u may,

1- if i recover like it is, will it know that its a 2tb partition extended into 2 931gb and hence restore the full 2tb or theres some other thing that i have to do then. (IS IT SAFE TO SAVE THE PARTITION TABLE AS IT IS)
2- if the above is the case, can i recover the files to as they were, AS TO THE SAME DRIVE ITSELF

thanks for ur support,

Setthe BIOS to boot from the optical when the machine boots it will show you ascreen with TRY or INSTALL > select TRY. You can of course remove the hard drive and any otherdrives when doing this as if the optical alone is the only drive left in themachine then the BIOS will only find it to boot from.

Whenit is finished - it takes very little time you will get a screen like in thepic .

Openthe drive you want > User and dig down until you get to the data / settingsyou may be able to copy / paste the material you want to an external source orother installed drive doing this.

Iam not sure if it will but I have recovered tons of data etc using this methodboth on "dead" or just plain drives that you cannot get data fromusing Windows.
Whether you have destroyed the data in that partition or not will depend on what you can see.

Maybe an outside chance might be running Recuva https://www.piriform.com/recuva < free version is good enough.

Hi everyone,

I am using Windows 7 home BASIC edition, 64 bit OS. My C: drive had 465 gb. I wanted to partition it and went to disk management. OS suggested to break 250gb only and I partitioned it. Now when I nall"New simple volume" on this unallocated space, everything went fine and on pressing finish button I was prompted the message:

"The operation I selected will convert basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed OS from any volume on the disk(s) (except the current boot volume). Do you wish to continue?"

Please let me know what should I do? I want to partition C: I also want to know how to increase the partition size of the partitioned size? and how to partition of my drive.?

A:Partitioning Error: Basic disk will be converted to dynamic disks

Hello cpsattawan. Welcome to the forum.

Don't convert the disk to Dynamic!

The are two drive file systems used for hard disks: legacy MBR (Master Boot Record) and the newer GPT (GUID Partition Table).

MBR disks can only have 4 Primary partitions. Any primary partitions added after 4 will require the the disk to be converted to a Dynamic Disk. Dynamic Disk is a supplemental system that lays over MBR. Windows can't boot from a Dynamic Disk. This system is used for data disks.

If you post a screenshot of your Disk Management window we can confirm this.

The easiest solution is to created an Extended Partition which will then contain Logical Disks. You can have many Logical Disks.
Partition / Extended : Logical Drives

Another solution is to delete one of the existing partitions. A common one to do this with is the Recovery Partition installed by computer manufacturers. What people do is burn the backup CDs of the Recovery Partition to keep on hand and then delete the partition, freeing a 4th Primary Partition for personal use.

A more complicated solution would be to convert the hard drive to GPT. But this process will delete all data on the disk so you need to be prepared with system Disk Images and personal data backups. You can practically have all the Primary Partitions you want on a GPT disk.

Hello all.

I have been researching this to no avail.

Here is the TL DR;

Old computer died which had two 400GB sata drives that houses a lot of family pictures and MP3s. The drives were dynamic and a 745 GB volume spanned across the drives. I now know these drives are also RAID-0, but I wanted to see if I could see any data on them and I had a USB sata dock. Learned the hard lesson that a dynamic disk wont be visible via USB no matter what (at the time I didnt know it was also a RAID-0) . I put the drive (which just happened to be the first drive) in my dock and somehow the drive got corrupted and became a basic disk. Pop up came asking if I wanted to format which of course I didn't. Odd thing is that the partition is intact (745GB) which causes the issue of not allowing me to convert it back to dynamic. It would seem if somehow I could just get it back to dynamic everything would work again or would be a heck of a lot easier to repair.

The issue is I cannot convert directly back to dynamic because it appears I don't have enough "free space" due to the partition reporting a 745GB volume which is correct.

I have tried multiple pieces of software mostly from Acronis, EASEUS, and Runtime (Disk Director, GetDataBack NTFS, Raid Recovery for Windows, and Data Recovery Wizard). Problem is these products don't fully solve the problem and I cannot reliably get the data off. The one product Runtime does have is raid reconstructor - but I am not ready to spend ... Read more

Hi, I was going to try dual booting Windows 8 on my laptop following a guide I found, and it said to go onto disk manager and shrink a volume to create another volume. The guide after the shrink only had two disks, and I had 5 disks (A recovery disk, HP tools and a blank one, along with my C disk, and the newly made one, named Windows 8 which I have now gotten rid of), after creating the other volume, it said about converting to a dynamic disk, I thought this was normal and clicked okay. After this I researched into dynamic and basic disks and found that only basic disks can contain a volume which is "active", where the BIOS boots Windows from, but because I converted the basic disk to a dynamic, the volume labelled active now doesn't display that it is active. (The guide's disk still said basic)
So now I am worried that my laptop won't boot, so I keep putting it into sleep mode (open and closing it) because this doesn't require BIOS. Please tell me whether it is safe to turn off my computer and turn it back on, I can't afford it not to work.

Here is a picture of my current and only disk on my laptop:

One more thing, I'm sure that the one which said active before was the one with no name on the left.

A:Disk management converted only disk to dynamic, will it boot?

From what I've read, the only major difference with dynamic disc's is that it's more flexible, in that it allows you more options in manipulating the disc itself. See link. You are fine with either setup.

I was setting up a Win7 new build with an Asus P8B75-V and an SSD. Although I previously have done clean installs with UEFI motherboards and SSDs, this time the install DVD created a GPT volume on the boot disk (much to my surprise and which I discovered opnly after loading all the apps, moving the email, etc, etc.).

Knowing a lot more about basic MBR volumes (and how to fix problems), I would like to convert the GPT to a basic volume. I have Acronis DiskDIrector 11 which can convert the GPT to MBR, but when I tried that, it rendered the disk unbootable. (The conversion resulted in a 124MB unallocated space, followed by a 100MB FAT32 volume (!?!?!), and then the rest of the drive as NTFS.)

Is there a way to convert a boot disk from GPT to basic and have it be bootable? Is there anything that can be done with the converted HD to make it bootable?

A:Can a GPT boot disk be converted to a basic volume?

Update re: Disk Director 11. According to Acronis, "DD11 does not support EFI." The EaseUS software which claims to have the option on converting partitions from GPT to MBR does not seem to actually have that option and the menus on the web do not match the (most recent) downloaded version. I am concluding that it cannot be done. (Sigh)

After I finished windows installation, I tried to create partition in unallocated space using > New simple volume. The sytem warned me of dynamic volumes > accept it.

A:partitions converted from basic to dynamic

Welcome to Windows Seven Forums.

Convert a Dynamic Disk to a Basic Disk

The reason you weren't able to create another primary partition is because you are only permitted to have up to four primary partitions on your hard drive.

If you need more then create a logical partition within a primary partition.

well scenario is I got my new dell 15r laptop with windows 7 basic loaded yesterday.. so backed it up and wanted to put my old PC's windows 7 ultimate version on it. I installed it, while installation it allowed to have only 4 partitions.
it already had 2 partitions
1) Recovery - 15gb
2) something i forgot ... some 40MB

so i made a partition of 125GB for OS
and rest of unallocated space ie some 660gb could not be allocated in more than one partition so i let it be unallocated
so after installtion got completed and OS started i went in disk management and tried to make that unallocated space of 660GB in 2-3 partitions.. but it converted all my previous partitions also to dynamic. even recovery partitions.
How do i go back to basic partitions?? particularly about that recovery partition and my C: (OS partition) ??

PS: i've naive on this subject

This is my first post, but I've been a long time lurker on the Seven forums; and they've provided a great deal of help. I googled for hours and could not find a solution to my specific problem. Wiping and re-installing is my last resort option, but I understand that it's entirely doable.

So I have what I believe is quite a unique situation. I got my new Crucial M4 64gb ssd a few days ago, installed windows to it, updates, etc. Prior to that I had Windows 7 Professional x64 installed to my Seagate Barracuda 1tb drive. Given the limited capacity of my ssd, I had partitioned 50gb of space (named it G:\) on my Seagate through the original install for the purpose of installing programs to it for the new Windows installation on my SSD. After getting the SSD all set up, I quickly noticed that 50gb was not enough space.

Before this mess occurred, dual booting was not a problem with the multiple partitions and whatnot.

So after taking a nap, I tiredly booted into the SSD and shrunk what was the C: volume on the other installation (and was now E or something) with the intent of extending the G partition into the unallocated space. Upon trying to extend it, Windows popped up warning me that it needed to convert the disk to a dynamic one (even though it didn't do this while in the Windows install from the Seagate, before I had the ssd) and that I'd lose the ability to boot from it. So I decided to cancel it. Then, since I had just woken up, I stupidly decided to re-attempt it an... Read more

A:Failed boot into Windows 7 after converting from dynamic to basic disk

It may be too late, but you can take a look at using PartitionWizard to get your hdd up and running again. Don't remember whether you can do this kind of thing with the free version.

Incidentally, 64 GB SSD is big enough to hold Win 7 and your programs. You will want to put your big profile folders, e.g., Documents, Videos, Music, Pictures on your HDD.

So I realized my system reserved partition had ended up on the wrong drive. I deleted the volume with the partition and tried to combine it with the rest of the disk by extending but it turned into a dynamic volume.

Is this going to affect me at all? The drive is only used for storage.

A:Disk converted to dynamic?

I'm not sure how you could try for extending it, and end up converting it instead, but the screenshot doesn't lie. You should be okay, but if it is just a storage drive (and you had your data backed up before the conversion anyway), I'd just delete the partitions and create one single basic partition for the entire drive.

I have 2 operating systems installed on my computer: Windows 7 and Ubuntu 9.10
When I was trying to create a new partition, I accidentally converted the main disk into a dynamic one and now it doesn't want to boot: it crashed at the GRUB and restarts the computer automatically.
I tried to revert back the partition codes from 0x42 to 0x07 for NTFS and 0x83 for linux but GRUB still crashes.
I don't really care that much about the linux partition, but I want to recuperate my main windows partition. I tried the Windows Repair from the CD but it doesn't detect any problems.
I don't really feel like backing up the whole system, formating the disks and all cuz I don't even have a spare HD for that.
Is there any other way around the problem?
Right now I only have access to ubuntu 9.10 in livecd mode.

Hey people,

After going through some problems, I found out that my disk is dynamic and that was what was causing all the issues.

A:Urgent Help Needed- Converting Dynamic Disk to Basic Disk

There is a tutorial here which may be of help:

Convert a Dynamic Disk to a Basic Disk

It is late here and this is the kind of thing I like to think through for a while before acting. It's better - and easier - to do it right the first time than try to undo a goof later on. You sound like you are being (very sensibly) cautious, so I'd recommend waiting for some other ideas before acting. I'll throw some ideas out there to get you started.

Do you have an external USB hard drive you can use to copy partitions to?

A quick look at the HP_Tools partition leads me to believe that it might be a candidate for deletion, but I'd check that before acting further. Unless HP gave you several DVDs worth of recovery discs, I'd say that the recovery partition is the only thing standing between you and having to possibly order a set of discs should something go wrong along the way. Does the laptop have a program for making your own set of recovery discs? If so, I'd do that now.

Someone else is likely to come along with some better ideas, but hopefully this will get you started.

Having available space in E: and needing more in Z: I performed a "Shrink" on E: of 75GB then "Expanded" Z: to the full amount available. I was warned it would change the disk to Dynamic (thus not being able to boot from it; I thought this would not be an issue as it is a secondary data disk).

2) Which disks would be primary partition and which one would be extended/logical partition?

The problem is that you converted your HD to Dynamic which is only meant to be used to span a partition across multiple HD's. Apparently you didn't see the warning message when you added partitions.

You can only have four Primary partitions or 3 Primary and unlimited Logical. Had you asked us we would have advised you that to keep HP System, Recovery and Diagnostics Tools (OEM) partitions bootable you'd need to convert C to Logical to add any partitions adjacent to that. How to set partition as Primary or Logical.

The solution to reconvert to Basic non-destructively is to boot free Partition Wizard CD version 4.2 which is the last one which offers this as a free feature: pw422.zip ISO - Windows Live.

Download the ISO, rightclick to burn it to CD using Windows Image Burner, or use ImgBurn.

Back up the files on the newly created partitions which tipped disk to Dynamic, which will need to be deleted before disk will convert back to Basic. If Win7 won't boot you can Copy & Paste - in Windows Recovery Console.

Plugged data disk into another computer via usb and it recognises it but won't read it.

Disk Manager says it is a Dynamic Disk - right clicking gives the option to "Change to Basic Disk"

Would i lose data on it if I did ?

How do I format a 2nd HDD?

Primary master: WD 80 GB IDE, running Win 2000
primary slave: CD burner IDE

2ndary master: WD 80 GB IDE, no data
2ndary slave: CD burner

external DVD burner, USB 2.

Sempron 2800+; 768 MB DDR; MSI motherboard KM4M-V; I've used the system for > 6 months.

I have installed an SATA board, but no drives are presently attached to it.

In "my computer" the 2ndary master does not appear, because it has not been formatted. The drive will be used only for storage.

I edited the registry per http://support.microsoft.com/default.aspx?scid=kb;en-us;317587 in an effort to Disable the Upgrade Basic Disks to Dynamic Disks Functionality. I re-booted, logged on as a member of the Admin group, but the wizard appeared again.

Thanks fo ryour help.


Disk management displays 2ndary master & spontaneously the "write signature" wizard appears.

Last night as I was attempting to install Windows 8 RP to test it out, I decided I would do a dual boot incase I didn't like it. It downloaded, burned fined and I went to make a new partition, and this is where things went south for me. It converted every disk to dynamic once I had created the new disk to install it on and for the life on me I can't get it to convert back to basic, so I'm pretty well screwed if something goes wrong.

Things I've done:
1) Attempt system restore - Ok, so I didn't have a restore point created so this is of no help.

2) I followed this guide found here on SevenForums and attempted all 3 methods - nothing worked
Convert a Dynamic Disk to a Basic Disk

3) I downloaed EaseUse Partition master to attempt to change dynamic back to basic, and still a no go.

4) Tried to install Windows 8 again and it would not let me delete the current dynamic disk partitions to start over

5) Tried HP recovery tools to set the computer back to factory condition and it wouldn't work.

I have no clue where to go from here. Is it possible to delete everything and start over from scratch or will it still be dynamic? At this point, i want a time machine so I can go back before ever attempting to make a dual boot. I honestly don't have the money to invest in a new harddrive right now so any help is GREATLY appreciated.

A:Cant convert Dynamic Disk to Basic Disk

Hello skyisover. Welcome to the Forum

You can't change the drive structure from any program that is running from the hard drive. You must be using a program that boots and runs from CD or DVD.

Assuming you have backed up all of your data (and even better, have a disk image of your C drive?):

Best: Download and burn a CD with Partition Wizard bootable CD on it.
Partition Wizard Bootable CD allows user to manage partition directly with partition manager bootable CD.
Then boot from the CD and use the tool to do the conversion. This has worked for many people.
How to convert dynamic disk to basic disk with Partition Wizard magic partition manager?

The nuclear option: You will need to run the Diskpart procedure from your W7 installation disk:
Command Prompt at Startup (Option 1)
Then use the "Clean All" command to wipe the hard drive. "Clean All" will write all zeros to the drive. It is slow but very effective.

When finished you will then have a hard drive with all unallocated space that you can format and use to reinstall W7 clean, and then reinstall all of your programs. It goes without saying that there will be nothing on the drive, so back up what you need.

What happened is that you probably had 4 Primary partitions before you tried to install W8. Creating a 5th Primary will automatically convert the drives to Dynamic. That partition was probably created by the W8 installer that defaults to a Primary Parttition. In the future, create your new (Log... Read more

Am trying to convert a 2TB Sata from a dynamic drive to a basic one. Hve followed all the steps... Removed all volumes, etc.

But i right click on the disk and click the Convert to Basic, I keep getting this message, "The operation is not allowed on a disk that is offline."

Cant's figure out why as the disk shows Online. Have also tried it through the Command Prompt using Diskpart. The status shows it is online, has no volumes and Read Only is set to 'No'. However, when I enter the Convert Basic command, I get the same message, "The operation is not allowed on a disk that is offline."

Grateful for any help...

A:Not able to convert a dynamic disk to a basic disk

Try wiping the HD first with Diskpart Clean Command to clear the boot sector before running "Convert Basic."

If that fails try using the non-destructive conversion tool on Partition Wizard which is still a free feature in version 4.2: pw422.zip ISO - Windows Live.

Burn ISO file to CD with Windows Image Burner, boot CD, highlight disk number, from Disk tab select Convert to Basic, OK, Apply.

If those fail then I'd run the HD maker's HD Diagnostic extended CD scan followed by Disk Check on a full disk partition you create.

Dynamic disks are a pain. Do not deal with them. If you would post a snip of your Disk Management, we could have a look what needs to be done. Apparently you already have 4 primary partitions.

I'm using Genuine Windows 7 HP SP1 x64 OEM version in my Acer Notebook.
Nowadays I have a trouble with my primary disk drive.

I Used 3rd party partition management software to shrink my "C" drive. The operation outside the windows wasn't successful and I faced a disk check after that. BTW It goes fine and my whole HDD becomes a dynamic disk. I want to convert it back to basic. But the convert option is inactivated in third party partition management softwares and even disk management utility. So how do I convert it back to basic?

I tried a clean custom windows installation, but I have following errors.

I'm unable to create, delete, extend any volumes here. All options are inactivated (gray) The only option available is "format"

And I was unable to continue Installing windows in the different drive. Then it gives me the bellow error;

Now what can I do to get my HDD back to the previous state?

Please help me.

Thanks in advance before.

A:How to Convert a Dynamic Disk to a Basic Disk?

What a mess. First you have to reduce the total number of partitions to 4 - better even 3. Then do this:

Convert a Dynamic Disk to a Basic Disk

If you end up with 3 primary partitions, then you can create an extended partition under which you can define up to 120 logical partitions.

Note: the 'System Reserved' has to be primary. All others can be logical.

I created a dynamic disk on Windows 7 64 bit Professional ((6.1.7601) with all applicable updates verified 10 minutes ago) by connecting directly to a SATA connection on the motherboard.

I then tried moving the disk to my Startech drive dock (SATDOCK4U3E).  It is connected to my motherboard via USB3.0 connection.  The station has a e-sata connection by my motherboard does not.  Further looking at the newer motherboards, e-sata
seems to be rare now as there are no Z170 motherboards listed on TigerDirect or NewEgg.

If I buy an e-SATA card should I be able to use the dynamic disk on my drive dock?

I am wanting dynamic disks because I am moving all my DVD's and BluRay disks to hard disk.  I am setting up multiple shortcuts to the movies with the book marks being stored in folders for actors, actresses, and directors.  For instance, the African

the drives as dynamic spanning.  The first DVD folder alone almost filled a 4TB drive.

If Windows 7 will not support this, will Windows Server 2012?  I am expecting before I finish to be using at least 16 disk drives and I would like to clone the drives to a backup set.  Also if Windows Server 2012 and I must move to it, does Wi... Read more

Hello, I'd like to know whether it is possible to have both dynamic and basic partitions on one physical drive - and if yes, could you tell me how to do it? I tried both searching and doing it myself, but I can't figure out an answer that I'm 100% sure of. Thanks!

A:Dynamic and basic partition on one physical disk - is this possible?

I doubt it. I think dynamic refers to the entire disk and each partition on a dynamic disk is simply a "dynamic volume".


Why would you think you might need dynamic disks? Or are you just curious and have no intent to use them?

I fixed it.

First Delete all the partitions of selected disk.
then I converted it.

Works like a charm. Thanks.

Not likely it was "some how".

More than likely, you said OK when a warning message came up asking you if you want to convert to dynamic when making new partitions.

That's almost always a bad decision.

We just converted our empty D drive to a Dynamic Volume, then the C drive. But, now, we can't boot up. It get's past the Windows XP screen, then we end up with a BSOD:


(STOP: 0x0000006F (0xC000000E, 0x00000000, 0x00000000, 0x00000000))

When we boot up in Recovery mode from the XP installation disc, it says that C:\Windows in an invalid directory! Are we b*ggered or is there a way to fix all this ?

Update: running chkdsk from the recovery mode tells me that the C:\ drive is an invalid path

Update again: I booted up in a Linux system (sorry) from a Live CD, and there're no hard drives showing in the /dev folder! No hda, hdb... I think we're totally boned, no?

A:[XP] BSOD after converting basic disk to dynamic

Was the C: drive the boot drive?

If so there's your problem, you can't have the OS installed on a Dynamic Volume unless you attach an MBR directly onto that volume.
You also should have received a message when converting that C: drive if it was the boot drive, that this operation is not possible or could cause irreparable damage to your data if you covert it to Dynamic.

All I can y is you can try to convert it back to a Basic Volume by using a 3rd party partitioning or drive mgmt tool, and hope that this wll make it accessible again.

I was changing some partitions in the Disk Management tool in Control Panel > Administrative Tools > Computer Management, and I accidently changed my boot drive to a dynamic disk (I thought it would only change the volume to dynamic, not the whole disk). According to Windows 7, the OS can't boot if it's on a dynamic disk, so I need to change it back. Did some research and found that the only way to do this is to clear all partitions from the drive. So here's where am I at:

It seems that I need to move all of my data to Disk 1, so that I can revert the other two drives to Basic and then move the necessary data back. I've got the space to do this, so I was wondering: How does the process of moving (or copying) the OS's files go? And am I going about this the right way?

I need to convert a hard drive from dynamic back to basic on a laptop running Windows 7 Home Premium 64bit, but appear not to have the option in Windows unless I delete all the partitions and lose everything on the hdd.

I have partition wizard 5.2 (free version) but it won't allow that function.

I hunted down a copy of 4.2 after reading a previous post that this does have the option but requires free registration, I clicked on the link to do this goes to partition wizard's website but a 404 error is displayed, not allowing me to obtain the free registration code, I suppose this is because 4.2 is no longer supported.

Can anyone help me out of this situation and provide me with the code which was free for a free bit of software?

Failing that how about someone give me an alternative solution or another package that is free and can do the same job.

All advice appreciated, this is somewhat urgent so the sooner the better.

Kind Regards,

Hi, Carlos37, welcome to the Seven Forums.

Even if you find a free alternative (there are a few out there) you should back up the data before proceeding else you will risk losing it.

There are many paid disk management utilities available as well but, again, back up the disk first, please.

I posted this question in answers.Microsoft.com and it was recommended that it be posted here instead. If this is posted in the wrong category could you please move it to the appropriate category. The one reply I received said that I cannot convert to a
dynamic disk without losing everything that is on that disk but just finished reading an article on MS website saying that the current partitions would be converted to simple volumes on the new dynamic disk and would still be bootable so would appreciate clarification
or confirmation. The issues of concern are those listed below and the primary one is whether the conversion will keep all of my info including the recovery partition (or equivalent volume on the dynamic disk), OS and still be bootable as mentioned below

A:Converting basic disk to dynamic without losing data

Hi jackdup,
First of all, I must tell you mirroring is not technically a backup solution, because if you accidentally delete a file, it?s gone from both hard disks.
And then for your problems:
1. Yes, mirrored disks requires changing them to ?dynamic disks".
2. The disk that you will use to mirror the existing disk must be unallocated. If it is not, you need to delete Volume to mark it as unallocated. This will destroy any data on that drive.
3. dynamic disk cannot be allowed multiple OS installed on the computer and you may have problems working with a dynamic disk in older versions of Windows.
4. RAID Level 1 can also be referred to as a mirrored array of hard drives. Mirroring is implemented when fault tolerance is desired. A mirrored volume is provides fault tolerance by duplicating data on two disks. If one disk fails, the data on the failed
disk becomes unavailable, but the system continues to operate using the unaffected disk. A mirrored volume is provides fault tolerance by duplicating data on two disks. If one disk fails, the data on the failed disk becomes unavailable, but the system
