How-To Geek Forums / Windows 7

I hope someone can help me with this problem.

Recently I bought a laptop HP g6 Windows Home Basic 64bit for my son. I am having problems with making new partitions. I'm using the Windows Disk Management option.

I reduced the size of the C Drive without any problems but cannot format a new partition. I got the following:

'The Operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk to dynamic, you will not be able to start installed operating systems from any volume on the disk(s). (except the current boot volume.) Are you sure you want to continue?'
Yes/ No

I chose yes and then I got this message:

'Dynamic Disks are not supported by this operating system or server configuration. Dynamic disks are not supported are not supported on clusters.'

I searched your site but could not find anything on this matter.

I have the Hp g7 with Home Premium -64bit and did not experience any problems increasing or reducing the sizes of the partition.

I got this message in Norton Ghost 2003, when i go to create backup image. Message are given below; 'Unable to find a free MBR slot in the virtual partition DLL. This is usually due to there being no free primary partition slots left on the boot disk.' Kindly tell me the solution of this message, Thanks & Regards, Yousuf. There are no free MBR slots on the disk. Cause: There is some limitation on disk type in Windows. You can only create 4 primary partitions at most. And, all my 4 partitions were of type ‘Primary'. Therefore, I was not able to create new partition any more. Solution: Changing any one partition's type to Logical from Primary will solve the. There must have at least a NTFS or FAT32 partition, at the meantime, it has enough free space, otherwise AOMEI OneKey Recovery cannot create Recovery Partition. But it is often the case that you can allocate some free space from system partition for creating Recovery Partition. For your case I think you have two issues need to address. The MBR Problem and change Drive C as your Primary. First, we need to fix your MBR Partition Problem then second we will change your Drive C to primary using EaseUS Partition Master. When fixing your MBR Partition Table there are two solve it; 1. StartUp Repair Option. Simply go on online and download a third-party creation tool for free. There are so many of them you can use like Recoverit Partition tool to create a bootable flash drive. Solution 6 – Convert the partition to GPT format. If none of the other solutions has worked, don't lose hope, perhaps this one will. Try converting the MBR partition to.

Thanks in advance.

Home Basic is limited in what it can do. Give this a try,

This is the download you want, as well,

You will have to boot your computer from the CD you burned.

MiniGeek, not quite true, but useful to have both options available in the event of a system crash.

Ah, were you intending him to run it inside Windows or as the boot disk?

For what he needs at the moment, run it from inside Windows. But in case of emergency in the future, have the CD handy.

Thanks for your help.

One question for Lighthouse - to run the wizard from within Windows I need to use the 1st link you posted right.

How many partitions are currently on the disk? If 4 then you have reached the limit for that disk without having to reinstall windows from a disk.
HP will sometimes have it formated with 3-4 partitions (System , OS , Recovery) the fourth is usually just there for seperate storage.
It would help to show us a picture too like this one.

Sometime the Windows Disk Manager does not like formating the space that you made if it is between two partitions, for reasons unkown to me, thus you have to use a thrid party program like those suggested above.

Windows allows four 'Primary' partitions on a single hard drive.

However, one of those could be an 'Extended' partition, and you can create as many 'Logical Partitions' inside the 'Extended' partition as there are letters of the alphabet!! So figure C is used, and D for your CD-Rom, that leaves you E through Z, or 22 'Logical Partitions'.

So you can create three 'Primary' partitions plus 20 'Logical' partitions.

From here:

Suggest you use the PW utility Lightouse suggested. You can use within windows or use the boot disk to run outside of windows.

While thats true, OEMs dont like using extended, it depends on the OP's current setup. So I need more input ;)

OEM's do use Extended. But I think not the Basic/Starter versions.
Simple experiment. Create 4 partitions on a clean drive. They will all format as Primary. Delete one, and create a new simple volume in it's place. It will arrive as Extended. (this is in Disk Management). Windows seems to have a problem there, in that it doesn't remove the old Primary from it's list.
Thus you need PW.

Curious, what vendors have you seen use extended? I see alot of cunsumer systesm on a daily basis and not one had an extended.

They don't come with Extended, it's only when you start messing around with partitions. (with DM)

generally OEM create a Recovery partition then the small System Reserved and then rest is OS partition.
Kelen is right, No extended needed there

There

don't get me started on that MS abomination dynamic disk(s). Lost a lot doing that

I think we maybe confusing the OP a bit. Suffice to say, he can't go wrong with PW.

Sorry for not coming back sooner, I had connection problems.

You are correct Lighthouse all of the above is very confusing. :)

I will go with the partlition wizard, I watched the video and it seems quite easy to do.

Failing which, my husband can take get a geek to sort out the partition.

Thanks for your help

Sorry for not coming back sooner. We did not have any luck using the partition wizard. My husband had it done by someone with more knowledge than us.

We kept getting a reading 'There are no free MBR slots'

I thought it would be a good idea to post our attempt.. maybe it will be useful to someone.

Thanks once again for all comments and help.

All th OP's slots were used up

On my HP laptop (year old), ALL partitions were primary...Boot...System...Recovery...Tools. I made the recovery disk and got rid of recovery partition...not the best way in hindsight but it doesn't matter to me as I use a W7 disk now not HP. Recovery.

What would be the best way to deal with that scenario for a non-geek if they wanted another partition like the OP...get rid of Tools?

New Simple Volume Greyed out


'I just assembled a new PC. It has a single 4TB hard drive. During Windows 10 installation, I created a 200gb partition to install to as the C: drive. It auto partitioned my drive into a 500MB system reserved partition, my C: drive, and two unallocated spaces of 1852.69GB and 1678.02GB respectively. The 1852GB space I can create a partition on, but the 1678GB space I cannot do anything with: Cannot create a partition, and cannot combine it with the rest of the unallocated space.'
The above example comes from a forum online and it gives you a real case saying Windows cannot create new partition from unallocated space in Windows 10. Here I will tell you detailed information about this issue. Here let's take a 3TB hard drive in Windows 10 as an example.
From the above screenshot, you can see there are two unallocated space. When right clicking on the second unallocated space, new simple volume greyed out. In addition, there is another situation that you also are not allowed to create a new partition when reaching the maximum number of partitions. Do you know the reason? Read on please.

Why Unable to Create New Partition in Windows 10


The main factor is the limitation of MBR disk. If your hard drive is larger than 2TB and it is in MBR disk type, you can't turn second unallocated partition into a simple volume. Why? In fact, MBR only can support up to 2TB disk. If the disk is larger than 2TB, the rest disk space will become unallocated space and can't be used to create a new simple with Disk Management.
Besides, in MBR disk, you only can create four primary partitions at most or three primary partitions plus extended partition. So if your partition has met the maximum partition number, you also cannot create new partition from unallocated space in Windows 10. Is there any way to solve such an issue? Fortunately, MiniTool Partition Wizard Free Edition provides two related functions to fix the issue.

How to Solve Can't Create New Partition on Unallocated Space

Convert MBR to GPT


If you fail to create a new simple with the second unallocated space, or the partitions meet maximum partition number, you can convert this MBR disk to GPT disk since GPT disk supports up to 128 partitions and it also supports larger than 2TB disk. MiniTool Partition Wizard enables you to convert to GPT disk effectively.
Step 1: Launch MiniTool Partition Wizard Free Edition, right click on the target disk which is larger than 2TB, then select 'Convert MBR Disk to GPT Disk'.
Step 2: Click 'Apply' option at last. Then you can use the unallocated space to create many partitions.

Set Partition Logical


There are already four primary partitions plus a unallocated space, here take this case an example. In addition, you also can change one primary partition to logical partition.
Step 1: Select a primary partition, and then click 'Set Partition as Logical'.
Step 2: Then you can create a new partition with the unallocated space. If there is no unallocated space, you can resize partition to free up some disk space.
Step 3: Hit 'Apply'.
In addition, there are some other cases, please click this post No Free MBR Slots. With MiniTool Partition Wizard, you can easily solve new simple volume greyed out issue. Just download and try it now.
