Merging Logical drive in to Primary - Not working

Q: Merging Logical drive in to Primary - Not working

Hi everyone,

I need some help. I installed Windows 7 on the C root drive and I'm trying to merge the logical drive which is 90GB to make it one big C drive partition. I tried doing it during installation, after installation and I also tried a program called EaseUS Partition Master and every time I try to merge, the C drive is shaded out.

Any suggestions would be greatly appreciated.

Preferred Solution: Merging Logical drive in to Primary - Not working

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Merging Logical drive in to Primary - Not working

You need to perform this operation from outside the Windows boot environment.

Do this:
1. Download FREE bootable version of Partition Wizard
2. Write it to a CD/DVD
3. Boot from the CD/DVD to start Partition Wizard
4. First merge the 9.77GB partition to C:
5. Now merge the logical partition to C:

Reboot - job done.

Hi everyone.

I recently formatted my computer and decided to partition my hard drive 3 separate ways.

I have a primary partition ( C: ) with 30GB that holds Windows Vista (Running home premium).

I also have a logical drive ( G: ) with 80GB that is holding all of my programs

Now I also have two other drives, a primary partition and logical drive (They have no files on whatsoever).

I want to merge these two to hold my documents (music, video, etc).
Only problem is disk management won't let me do it and Partition magic would not work with vista when I installed it.

Does anyone know of a way to merge my primary partition and logical drive (they can be formatted)

I have already tried formatting one volume and extending the other.

Thanks in advance.

Can Windows xp disk management merge 2 partitions, one of them is the primary partition where windows resides?

A friend's computer is having Windows installed in a very small primary partition (2.5gb) and its making everything crawl like a turtle, too slow.
I thought I try increasing the windows partition by adding another partition to it (merging) but i did not see that option available. Is that so? or is there a way to do it?

if not, is there a freeware tool available anywhere to do this?

A:merging primary partition with a logical one

Not with XP's native tools. Diskpart.exe will do it, but not from the partition it's running on, so that means not the C: partition.

You can do it with diskpart if the drive is put in another computer as a secondary.

And "merging" is probably not what you will end up doing. It's just a matter of semantics, perhaps, but "merging" implies that the contents of both partitions will be combined and saved. I don't think you can do that with diskpart. But, you can save everything off the larger partition, to CD or somewhere, and then expand the smaller one into the larger, thus having the same result, except that the contents of the larger partition are not preserved.

Can this be done?

EASUS won't let me.

My C: drive is running out of space, so I took 7 gigs from my D: drive and now it is unallocated.

How can I merge it with the primary partition?
It only lets me merge it with the drive I took it away from.

Many thanks.

A:Merging unallocated space removed from logical to primary disk

If it's really on a different (physical) drive you cannot do any such thing.

If it's on the same drive and the unallocated space is contiguous with the partition there should be no problem resizing the partition. But, your thread title indicated that the unallocated space is in a logical partition, and you can't extract it from the logical partition.

I have 4 SATA drives. Disk 1 is C: (Primary with Windows 7 64 bit). Disk 0,2 & 3 are data drives (D,E,F).

I am having bad sector problems on the C: drive and have ordered a new one. However, I was wondering if I could turn the D: drive into the C: drive by shutting down the computer, removing the faulty C: drive, then booting to the W7 (RC 7100) DVD and do an install. Then when the repalcement drive arrives, install it as a data drive.

Right now, the D: drive has just one logical partition and some data that is backed up.

A:Can I make a logical drive primary?

If I understood, you have four different hard drives. C:\, disc 1, has Win7 x64 with bad sector. You backed up the data on the second hard drive, D:\, and want to make Primary.

Well, you can but you will to install Win7 on it and format it during the installation. But if you want to put it simply Primary, the answer is No. You need an OS on the hard drive for it to be primary.

Hello friends,

Sorry for dumb question . I have recently fresh installed Windows 7 on 500 GB SATA disk. After created partition it look like following.
Please check and advice me that d:\ setup as Primary partition and f:\ displayed as Logical drive. Is it ok ????
How can it possible if i want to change f:\ as Primary partition.

Thanks in advance.

A:Primary partition or Logical drive ???

It is completely normal for the F: drive to be a logical drive. There is no reason to change it, and a number of reasons not to.

Logical drives were designed many years ago as a means of having more than 4 partitions. There can be a maximum of 4 primary partitions but no limit on logical drives.

Hi, I partitioned my hard drive and created a new simple volume but it has appeared as a logical drive. Why is this? I want to convert it back to primary partition so I can add the space back to my main drive. How do I do this?

A:How do I convert Logical Drive to Primary Partition?

Windows will normally create a logical partition for the 4th drive due to a limitation on the number of primary drives.

It looks like you have nothing on the logical drive F, so you should be able to just delete it in Disk Management.

That space will then become "unallocated space" and you could then extend D to take up that space.

If you want to add that space to C rather than D, you will need a third party tool such as Partition Wizard.

Hi All,

I had intended to create a new partition by shrinking my C drive, to dual boot with the Windows 10 technical preview.

I appear to have changed my C drive from a primary to a logical partition. It still works perfectly and have no issues.

I did not install Windows 10 in case the partition created includes files necessary for Windows 7 to run.

Is it possible to delete the windows 10 partition I created then change the C drive back to primary without any data loss? From there could I also create a new logical partition or use the recovery partition to install Windows 10? Please see the attached picture for a preview of disk management which should clarify things further.

Thanks for all your help in advance!

A:Changing C Drive back to primary partition from logical

Hi Nick21 and welcome to Seven Forums,

I believe you can just right-click on your Windows 10 partition and select delete volume. That will make it into unallocated space which you can then extend your C drive to.

Then, when you want to install Windows 10, follow this tutorial. Windows 10 - Dual Boot with Windows 7 or Windows 8 - Windows 10 Forums

Hi everyone!
I have an external 931Gb Seagate disk.
I wanted 5 partitions and it came out with 3 logical drives and 2 primary (all healthy)
After an infection with ransonware I had to delete one from the 2 primary partitions but suddenly
at the same time got unallocate one from the 3 logical drives too, like if they was connected (?).
So I lost everything in it which there was very important backups not infected.
Is there an easy way to allocate again this logical drive and find again the files was in it?
Why happened this? Is it normal?

Win 7 recognizes my UST ATA hard drive but I want to test it before I spend hours moving data to it.

How do I test the drive?

Since it is formated as a primary drive does that mean it must on when I power up my computer?

What happens if I turn it off and on again.

Should I convert it to a Logical drive?

The most frustrating part of the process is the drive is not consistently recognized by Win 7, VM Player or XP Home. EASEUS Partition Manager failed several times to complete a move, format, delete partition.

I recently converted a Western Digital 500GB drive from Raw to NTFS. Saturday I used an Elevated Command to format it ~ F: /NTFS /Q. At that point Win 7 recognized the drive and I backup 140GB to this drive.

Sunday morning Win 7 could not recognize the drive.

I then installed VM Player, XP Home Edition and ran EASEUS Partition Manager. PM found several Partition in front of the F drive. PM removed all of the partitions and formatted the drive.

Win 7 currently recognizes the drive. Computer Manager reports it as:

F: Simple, Basic, NTFS Healthy (Active Primary Partition) 465.7 GB Free: 322.9

A:USB ATA HD: Primary vs Logical

Being Primary does not mean it needs to be on when you power up your computer. There is no need to convert to Logical unless you run out of Primary partitions.

Second, how they should be set up, for a Windows machine?

A:Primary, Extended, Logical

Primary are best for OS, Logical are best for data. This way the boot files cannot be derailed to a data partition since Logicals cannot host boot files.

You can have a total of four Primary Partitions, or three Primary and unlimited Logical. To understand better and/or create a Logical use Partition / Extended : Logical Drives - Windows 7 Forums,

I'm making some progress now with my new W7 install on MBR via a UEFI motherboard.

I have a question: After first deleting the original install partition with a program that has a GUI (don't remember its name) the Disk 1 partition showed as 'Logical'. After using the app to create a 'Primary' partition formatted in NTFS, it now shows that its type is Primary.

Does the presence of either of these labels (Logical, Primary) or both, automatically indicate an MBR partition?

please help me friends.

A:Logical Partitions to primary

1. You cannot make another primary because you already have 3 primaries plus 1 extended partition. That is the maximum. DO NOT ATTEMPT TO PLAY WITH IT. You will regret it because all your partitions would be converted to dynamics - a real problem.

2. You do not need a primary partition to install XP. A logical partition will be OK because the XP bootmgr will go into your D partition. That looks like the 'active' partition. Check in Disk Management.

3. On any system you really only need 1 primary partition - for the 'active' partition.

First off, I'm fairly equally skilled with Windows (especially the NT kernel family), Mac OS (from System 7, c. 1991, to OS X Snow Leopard), and Ubuntu Linux (8.04 to 11.04). That said, I prefer Mac OS X, as it doesn't have issues like these.

I'm trying to repartition my hard drive into two equally sized partitions: one for an existing Windows 7 install, and the other for a pending Ubuntu 11.04 install. My computer originally came with Windows Vista Home Premium 32-bit, but the computer (an HP Pavilion a6400f) has a 64-bit CPU, so I decided to upgrade to Windows 7 Ultimate 64-bit. I performed a clean install rather than an upgrade install, so there are two partitions: one for Windows Vista (Primary) and Windows 7 (Logical). Why it installed like this is beyond me, and it's giving me some trouble. I want to delete the Vista partition to make room for Ubuntu, but it's an active primary partition, so I can't delete it.

Is there any way I can transfer the files from (just) Windows 7 to an external hard drive, format and partition the internal hard drive, then transfer Windows 7 back into a primary partition on the internal, and make it bootable? I don't think I can just reinstall Windows 7, since it's an upgrade disk.

Any help would be appreciated.

A:Logical to primary, with a twist

Even though you prefer mac, I'll still help you; have a look through this info below.

It would be best to do a complete wipe of the Hard Disk Drive / Solid State Drive and then start the installation process again, have a look at Step One of the Optimize tutorial below; after you have copied out or made back-ups of the data you need to save to external media, then boot the Windows 7 installation media to do the wipe secure erase to the HDD / SSD and be sure to post back with any further questions you may have and to keep us informed.

Whether you use diskpart to run either the clean all command to completely wipe a HDD / SSD or just the clean command to remove the format configuration data and don't use diskpart to create at least a single partition to do the installation to, letting the Windows installer do the format, the new Windows 7 System Reserved partition will be automatically issued, if you want to make your own decision whether this partition is added, study these two (2) options below. If you do not want to create the new Windows 7 "System Reserved" partition use the outline in Step Two #2 to create, format and mark Active a single 100GB partition to do the installation to.
If you do want to create the "System Reserved" partition use the outline in Step Two #3 to create, format and mark Active the System Reserved partition and then create and format the 100GB partition to do the installation to.

Hi all,
I have a laptop that used to be running XP, I installed windows 7 onto the D: partition that I had for a while. This partition is Logical.
After using win 7 for a while I had no use to the XP partition and wanted the space back.
I formatted the partition that had XP on it, that caused my laptop not to boot because it lost BOOTMGR, I was able to fix it by copying the win 7 install disk to the C: root. That let me do a system repair and boot to windows 7. Thankfully.

Well, now I want to get my C: back and I'm not sure of the best way.
-Can I change the D: from logical to primary/active? I haven't been able to do it using -MiniTool Partition Magic (it sees the partition as Unallocated)
-Can I just merge the D: and C: back into one partition?
-Can I transfer the D: to C:

Not really sure of the best plan of attack. But from what I understand I need to first get the D: logical partition that has win 7 set to be primary/active?

Here are the screen shots of computer management and the 'unallocated' partition.

A:Win 7 on Logical D: want to move to Primary C: or merge both

I would clean reinstall after wiping the HD since Win7 was never installed correctly by booting installer so it would claim C when booted: Clean Install Windows 7

In addition there are other problems since I've never seen PW CD fail to see the booted Win7 partition. Try using the PW boot CD.

PW should not only see Win7 but if you want Win7 on D allow you to convert D to Primary, then you can follow these steps to resize into C while recovering the System boot files into Win7 by marking Active and running Startup Repair 3 times: Partition Recover Space Used by an Older OS

I wish to hold some programs and some data on non-system partitions with no boot requirements.

What are the benefits (performance and otherwise) of using a partition :-
Logical on my MBR style HDD
Primary on my MBR style HDD
Primary on my GPT style HDD

I have adequate unused space on both the HDD,
My system is on an OCZ SSD
My motherboard is not uEFI capable hence cannot boot GPT.


A:Benefits of GPT vs MBR Primary and MBR Logical Partitions ?

From the user's standpoint there really is no perceptible difference in partition type for user data and installed programs. In everyday use the F: drive is the F: drive and neither you or the system give a hoot about it's type.

The main benefits of GPT partitions are compliance with the requirements of UEFI systems, the recognition and use of partitions or hard drives larger than 2.2TB, and the ability to have up to 128 primary partitions.
If none of the partitions on a data hdd are larger than 2.2TB then you do not need GPT to use them.

The main benefit of a MBR primary partition is the ability to boot an OS from it.
Windows creates primary partitions first by default. The reason: "why not?".

The main benefit of a logical drive is that it allows a MBR disk to have more than 4 partitions, since a MBR disk is limited to only 4 primary partitions.
A logical drive does not perform any faster, slower, or differently than a primary partition.

Be careful when creating that 5th partition on a MBR disk. You do not want the system to create a Dynamic Disk. Make sure it is going to create a logical drive.

So you just decide what you have and what you need to do. Don't over-think it.
Hope that helps!

That`s because it`s not next to C, just extend C into D (but D is a Logical partition, so that may be an issue.)

Windows 7 is coming pre-installed on my new PC from Dell. It has two 500GB HDDs.

I want to partition the first drive into just a couple of partitions. I guess I will have to shrink the main partition to about 100GB for the OS and apps.
But my question is: that partition with the OS and apps will be a 'primary' one...what will my next couple of partitions be? Logical? Extended?

I'm not sure how to decide what type of partitions to have. Any help would be great.

A:Difference between Primary, Extended, Logical Partition

They both should be Primary. The first 4 partitions can be primary. After that, you need to create a logical drive, which would be your 3rd partition. In the logical dive, you can create unlimited extended partitions.
The advantage of a Primary partitions is that you can boot from it.

Hello, i have a question regarding partitions: my HDD has both Windows 8.1, 7 and XP installed, each on a different partition (7 and 8.1 both primary partitions and XP logical). It also contains a 'system reserved' primary partition and 'other' partition wich is logical. The problem is, i have about 50gb unallocated disk space and i want to create a new partition to use. When i'm trying to create a new partition (using EaseUS Partition Master), a message pops up saying that i have to convert an existing primary partition to logical, then should try again. So here's the question: wich primary partition i need to convert into logical ? The one with Windows 8.1 or Windows 7 or System Reserved ? I don't want to lose any of my operating systems. I mention that when i start the laptop i choose wich os i want to use from Windows 8.1's bootloader using a menu with 3 options (start W8.1 or 7 or XP). Any advice would help me.

A:I need to convert a primary Windows partition into logical

On an MBR disk there can only be four total Primary partitions, or three Primary and unlimited contiguous Logical partitions.

You can add the 50 gb to C using Disk Mgmt Partition or Volume - Extend which only extends to the right, or add all or part of it to any other partition using How to extend partition easily with Partition Wizard - video help. This is a very cool tool which can borrow or add space to/from any other partition whether or not its adjacent, Primary or Logical. But I would use the Partition Wizard boot disk which is safest.

In order to add another partition due to the limitation on Primaries it would need to be Logical, but it is separated from the Logical partitions by System Reserved which is booting all OS's and C which are both Primary, and Logical partitions must be contiguous or adjacent to each other.

What exactly is the unlettered Logical partition after XP partition showing 1.03 gb used? What you could do is format it and issue a letter, then use Partition Wizard extend to add all of the 50gb space to it thereby having a new 50gb+ partition in the Logical block.

I am trying to create 5 partitions on one of my drives but for some reason I can only get 4 set up. After 4, the last empty part of the drive won't give me the option of making it a partition.
If I try to make the 4th primary or if I make it extended, I can't use that last 10 gb's as another partition. Only if I combine the 4th and 5th part into just a 4th partition will it work out. But I really want this 5th partition.
Windows tells me that I can only have 4 primary which is why I tried to go the route of making the 4th and 5th extended - then logical.

Not working, all I get is details option on that last drive and no create a partition option.

Thanks in advance.

URGENT!! Hey guys... First of all I would like to say Hello to everyone here.. Its been MANY MANY years since I was in a forum.. I was mostly enjoying reading them and getting my answers or solution from other peoples problems etc.. Until now... I know that this Thread is not the correct one but I thought I should start from here until someone redirect me somewhere else.. Back to my problem..

I bought a new cheap PC with an MSI G31M2 v1 board, with an Intel E4500, DDR2 667, Maxtor 160Gb SATA and an ATI 4770.. The specs are just there for future reference.

I install Vista Ultimate on it. Everything was FINE until, after my last restart half week ago it gave me the BSOD with the error "STOP: c000021a (Fatal System Error)" blah blah.. I tried everything I could with no success.. Anw thats NOT my
problem now..

I had 2 Partitions. One Primary 20Gb with the OS and another Logical 129Gb for ALL my data files!!

I inserted the Vista CD to do a re-install and in my desperation and FOR MY BAD LUCK AND STUPID HEAD and not taking seriously the WARNING message "Extending a partition is not a reversible action. If you proceed, you will not be able to undo this action later" I choosed Options from the setup screen and I choose EXTEND and I believe my LOGICAL Partition was Merged with my Primary and now almost 60Gb OF DATA that were on it are gone.. And they were VERY importand files..!! I have HIREN'S v10 but nothing.. Also from the HIREN'S Diagnostics it... Read more

This is from a blog post I am doing. The questions are at the bottom

<strong>A Word on Primary/Extended/Logical Partitions
</strong>The difference between primary, extended, and logical partitions, to say the least, greatly confused me. Here's what you need to know. When you partition a drive you have the option of choosing the new partition to be primary or extended.

Primary partitions are partitions
<li>from which you can boot an OS</li>
<li> automatically get assigned to a device location</li>
<li> partitioning them must involve the assignment of a filesystem (ntfs, ext4, FAT32, and the like)</li>
<li>have a maximum number of 4 (you can only have 4 primary partitions on any given single hard disk)</li>

Extended partitions
<li>have unlimited count per hard disk (there's no 4 maximum, like with primary partitions)</li>
<li>do not get automatically assigned a device location (nor drive letter in windows)</li>
<li>do NOT get formatted with a filesystem (filesystems are assigned later)</li></ol>

Here's a very helpful diagram from gparted.

"IMAGE of parittions

Now I made this overly complicated to illustrate the different partitioning types:

<li>Partition 1, NTFS, Primary, 300GB,<strong> 1/4 Primary</strong>
<li>Partition 2, NTFS, Primar... Read more

A:Understanding Logical, Primary, and Extended Partitions

Basically, the
if I do linux (ext4) (must be primary for it to be bootable with linux os, right?)
and a swap. Doesn't the swap have to be primary, too? How could it not?

I liked the idea of doing ONE extended with an ext4 and a linux-swap as two logical partitions within the extended, but then the ext4 with linux os couldn't boot??
BASICALLY: If you make an extended partition, (can one of those logical partitions be used as linux swap)? AND NONE of those logical partitions (nor the extended) one can boot from, correct??

This is slightly irksome and the 4 primary partition limit seems unnecessary.
(please don't bother responding if you've never worked with these three types of partitions)

I have bought a new 500GB internal hdd. Now I want to install windows 7 on it. I want to create 4 partitions like below:

C: Windows .......... Primary 64.4GB
D: .......... Primary 99.9GB
E: .......... Logical 99.9GB
F: .......... Logical 99.9GB
(System Reserved 100MB)

I have a windows 7 installation cd and also a third party bootable partition software (easus p.m).
Problems I'm facing are...
1. How to create those 2 primary and 2 logical drives?
2. Why the sizes 64.4 and 99.9, can't they be 65 and 100?
3. Can I simply install win 7 on a single 64GB partition and leave the rest unallocated, then create rest of the partitions later?

It's my first time so I'm kind of confused. Any detail guidance would be in my great assistance. Pls pardon any mistakes.

A:How to create Primary and logical partitions in my new harddisk

If you install Windows to unallocated space it will create System Reserved and [C] partitions, both partitions will be primary.

The System Reserved will have the boot manager and be the Active partition.
The [C] partition is where Windows will be installed, and be the Boot partition as seen in Disk Management.

If you pre-define a partition to install Windows on, it will be the Active partition having the Boot Manager, and the Windows OS.
That's my experience, with Legacy BIOS, and MBR disks.

I don't know what you are going to use [D] for, and why you want it as Primary.
I prefer Logical partitions for all except the partition that has the boot code, that partition MUST be primary.

You can use Minitool Partition Wizard (free) for better adjusting and fine-tuning the new HD partitions.

Make sure you have your current HD, OS, and DATA backed up completely on a different device, before making any changes.
Use a program such as Macrium Reflect free for the creating a Backup Image of the OS partition.

This screen shot shows what Macrium Reflect imaging program sees my drives as.

It shows D: on Disk 1 as active and G: on Disk 3 as active. What does this mean?

I assumed that I was booting from C:, which is my Win 7 drive.
Am I really booting from D:?

I believe D: is going bad physically. Norton Ghost says there are too many errors on it to make an image. If it goes bad, does it mean that I won't be able to boot my pc?

These is lots of info. on the Net about how to create these different types of drives, but info. on which is the best one to use for different purposes and why is very thin on the ground indeed.

So I'm a bit confused here. Not about the should/shouldn't separate paging file issue and I really don't want to go there as it's been argued to death all over the Internet. I'd just like to give it a try on a separate hd. I have an empty 40G hd that I'm going to format as 34G for back-up data that I'd like as logical FAT32 and the 5-6G left for the paging file as Fat 32. What will actually work and is doable and will give me drive letters for each?

Should the paging file be the first section of the hd or the last?

P.S: I do realize that to create a logical drive I need to create an extended drive first if a logical drive is recommended for either partition.

Hello all...
I have problem that i cant solve for days.. I did most of the things that i found on different forums, used some partition programs but still cant solve this...

1st, here is the picture and i will explain:

I made that unallocated space from partition E and I would like to merge it with partition C, bcs as You can see, i have only 120MB free there... Neither Disk Manager nor some other program can merge it... Also, when i make unallocated space from D partition, then it is between D and E partition and still cant merge with C...

Is it possible to merge that unallocated space with C? I really need more space on C...

TY in advance for help...

Win7, XP Dual boot- Install OS's to logical or primary partition? Pros and Cons
As many of you know here some versions of Win7 create a "100 /200mb System Reserved" partition which the Win7 installer installs the boot files to.
(Because of this Win7, XP don't "have to" be on a primary partition but instead can be installed to logical partitions.)
Q: What are the PRO's and CON's of installing to logical partitions, instead of primary - as it applies to these (2) OS's?

My concerns are reliability, accessibility to partition (OS) which may need manual editing to restore to working condition, being able to image, restore from images without issues via Acronis True Image mostly.

My other main concern is I'm looking to HIDE the "system reserved" partition in XP as is done by the Win7 OS so XP is on "C" instead of "D" as some programs freak out if they don't see "C", but D instead.

Currently I have:

System Reserved 200mb (System, Active-Primary)
Win7 on first logical (Boot, page,crash)
XP PRO SP2/3 on 2nd logical
DATA on Primary.

Was thinking about deleting all partitions (again) and getting rid of the 200mb system reserved partition as "some" programs in XP might not like being on "D:\"

(XP unlike Win7 "sees" the System reserved partition as "C:")

Scenario#2 - re-install as below:
XP PRO SP2/3 (1st Primary)- Win7, XP boot files
Win7 (2nd Primary)
DATA on Primary (or ... Read more

A:Win7, XP Dual boot- Install OS's to logical or primary partition? Pro

Read the guide! Dual Boot Installation with Windows 7 and XP

When XP is installed onto the first primary followed by 7 afterwards on a second the 7 boot files taking over as the default OS in the process are found at the root of the XP primary being already present. When booted in 7 you simply select the drive letter to be used for XP when going into the Disk Management tool to make that partition available.

Typically D is best reserved for the optical drive leaving E, F, G, as the suitable alternatives for a second OS's drive letter. Having two dvd burner here any secondary install on a second drive is bumped upto G while flash drives may be seen as F since D and E are reserved for the two opticals.

IF 7 is installed before XP as detailed in Method #2 you can opt to prepare the primary prior to the 7 install using the drive tools on the 7 dvd, Disk Part, or some 3rd party drive partitioning program. If the 7 dvd's drive tools are used to create the primary you will then likely see the 100mb reserved if proceeding right into the fresh install.

To avoid seeing the 100mb as a separate partition you either cancel the install once the primary is made to reboot and reload the installer to use the custom install option or prepare the primary ahead of time with another option for 7 install to that alone and no 100mb reserved is seen.

The option for not seeing XP available of course would be installing XP after 7 but then need to repair the 7 startup but need to add XP in... Read more

Hi there!

I've been trying for the past hours to delete two logical drives so as to obtain some unallocated space that I could (in theory) transform into two new and shinny primary drives, on which I wish to reinstall XP, one as my main partition, the other to try out new programs.

Of course, things didn't work out that way!

So, now I'm stuck with my system on a logical drive (C {Boot},

some free space which I can only turn into a new logical drive

and my data on another primary partition without Windows on it, but still saying (E {System}

Whenever I try using Fdisk from a floppy to create new partitions, they always show-up as logical drives...

Any ideas? The worst thing is that I've done this many times in the past and can't figure out what I'm missing today!
