The System And Data Partition
Dec 30, 2009
I just installed Windows 7 Ultimate 64-bit and saw that the users private and public data are still saved in the C:Users of the system partition.
So, I'm looking for a specific guide for Windows 7 that separates the system partition from the users private and public data, saved in another partition on the same disk. In addition, private data created during the creation of new accounts (including the Administrator account) must be saved directly in the other partition.
In other words, in the C:Users directory, the All Users, Default and Default User directories must only remain and its must to be fully functional.

How can I access a system partition to read and copy data? Two partitions were merged together and ended up as a system partition. All of my data files are in there.

I recently (~2-3 months ago) installed windows 7 on a brand new 1TB hard drive. This hard drive is broken into two partitions - C & G. Windows 7 is installed on C; and G is only for data storage etc. Here is the description of partition C from Disk Management:
C: Simple Basic NTFS Healthy (Boot, Page File, Active, Crash Dump, Primary Partition) 98 GB
Unfortunately, "System" is missing from that description. Somehow "System" ended up on hard drive L - an old 80GB IDE drive that has migrated from build-to-build. This drive has just started on the *hopefully* slow road to death. I decided to retire this drive when I discovered I couldn't securely erase it because it is the System partition (there is only one partition on this drive).
So, how I can relocate the system drive data to another drive (preferably C) in the safest way possible. I found a solution here: [URL]. But I don't want to copy the entire contents of L to a new drive, all I want is the data needed for booting, and to securely erase everything else on L. Looking around, it seems I may be able to boot from a Windows 7 repair disk and recreate the system files on C, but this seems risky and likely to require a full re-install if something goes wrong.

I have my HP Laptop which came with Windows Vista as the OS. I want to upgrade to Windows 7 so I bought Windows 7 from my local store.I entered the disc and did boot from CD. It reached to the page where it shows the disk partition. I deleted the partitions and created new one. However, whenever I create the partition, it creates a primary one and gives me error saying Setup was unable to create a new system partition or locate an existing system partition.

I have a copy of windows 7 from a friend. (USB, possibly enterprise)It runs well, is official and can be re installed and is verified through the Microsoft site, so the media doesn't seem to be a problem.I was able to install Win7 Ult x64 on my WinVista HomePrem x86, but I went back through to clean the hard drive (it was full, I didn't format before) and after low level formatting I cannot reinstall the OS. The harddrives are completely empty, and I get stuck at "Setup was unable to create a new system partition or locate an existing system partition," after hitting next when you are selecting the HD partition to install on. I tried a couple of things already:
-Installing on another harddrive
-Formatting using Hiren's bootcd
-Using a hard drive with XP installed to see if it is an upgrade and not a full version (no luck, still wouldn't install)
-diskpart > list disk > select disk 0 > list partition > active \ in cmd..I have three hard drives attached to the computer right now, they can't all be broken. T.T

Recently my SSD failed so I tried installing windows 7 from DVD on my HDD but I always get an error message: "Setup was unable to create a new system partition or locate an existing system partition."I've tried everything I could find here: I gave boot priority to the HDD, I unplugged every other device but nothing seems to work.

Through a series of shenanigans involving experiments with mirroring on Windows 7 64 bit using Disk Management, and then subsequently removing the mirror after having recurring errors/problems with the synching, My 100MB System Reserve partition has ended up on a separate partition than my system image. For instance: Disk 1 System C: Healthy (Boot, page...) Disk 0 Healthy (System Reserved...).
In addition, the System Reserved partition has been assigned a drive letter "G:" or "E:" and is now visible in explorer and it won't allow me to remove it and supress from explorer view.
I'd like to
1) move/create the System Reserve partition to Disk 1 (with System C: drive)
2) remove the System Reserve partition from Disk 0 to free it all up as a data drive
Do I use command below to create a System Reserve on Disk 1? bcdboot C:Windows How do I then delete the System Reserve partition on Disk 0. Also a byproduct of all of this, when I reboot now, I have a "Windows 7" option and a "Windows 7 Secondary Plex" option. The "Windows 7" option no longer boots (it's stops while the logo panes are flying in circles to form the logo and goes into a fix loop that never fixes it). I have a feeling it's looking for the old mirrored hardware configuration or something. However, "Window 7 Secondary Plex" option does boot just fine. Do I use MSCONFIG to remove the "Windows 7" boot entry so I don't get this annoying option at boot?

I have somewhat the same problem as this guy has:
http://windows7forums.com/windows-7-installation-upgrade/14819-c-drive-no-more-visible.html
I read that you guys might need the Diskmgmt information in his topic so here it is:
I had the RC which was dual-booting fine alongside XP. Then I got the RTM, burned it, booted up with it, deleted and formatted the partition on which 7 was (which was the C drive) and installed the RTM.
When I did this I noticed that the os selector had disappeared. So I installed EasyBCD to try to fix the boot-loader but I think I messed up in this stage.
Cause when I tried to boot in XP, I got the "Error loading operating system".
Tried some things to fix it, (which involved reinstalled 7 again just to boot up in it to try to fix the boot-loader), didn't work, gave up.
Put in the XP cd, deleted the XP and 7 partition, and created a new 100GB partition and installed XP on it. ( My 400GB Data partition was still visible and accessible in this stage).
Then I put in the 7 dvd, booted it up, created new 100GB partition out of the leftover unformatted space, and installed it.
No problems during installation, computer rebooted, I got the nice boot-loader screen with the "Earlier version of windows" and "Windows 7" option. Everything still ok, boot up Windows 7 and there I notice that my Third partition, with all my data had disappeared! =S
I'm thinking with is this, I reboot into XP, and there it has vanished as well! What should I do now? I want to get at-least the Data back, I don't care if I have to format my entire drive again and install XP and 7 all over.

I have Windows 7 ultimate 64-bit installed on DELL desktop (Optiplex 990) i7 Core. I have two HDD: Disk 0 contains the operating system 500GB. and Disk 1 empty 1TB.
I want to make a partition on disk 1 to mirror the operating system partition and keep the remaining for data storage. I tried to do but I had the following error message: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid."
I tried to attach a screen shot but couldn't.

I have W7 64 bit and have my main HD partitioned c:/ - 100 gig, F:/ Data - balance of 500 Gog. I have retained the old XP filing system of most self generated data being in a main "My Documents" folder with sub folders such as My Music, My Word Docs, My Pictures etc (I include Outlook in this). My data partition therefore holds most of my data and is frequently backed up to another drive with Synch Toy. However the Users folder is still on the C: drive and accumulates data such as downloads etc. I have Googled this issue and it seems very difficult to move the Users foler to another partition.

I've got my 500gb laptop hdd partitioned with majority on d data partition (have not installed anything ever to d - only c). I do have my user folders relocated to the d part. Where should I install or set up game directory for my d partition? (Current game I'm installing is recommending c/prog files(x86)/published/game title) should I just change c: to d: even though those folders don't exist, installation will create them? Are steam games installed to different path normally than x/program files. How might future steam game installs affect where/what directory folders? Any program for remapping or whatever would be needed to use an xbox 360 controller for pc games?

I accidentally deleted a partition in Windows 7 (dynamic disk) using the disk management tools. That partitions is full of works and photos from the last 2 years. Are there any way I can recover the data? The space left by the deleted partition are still un-allocated at the moment. Do I need to create the partition prior to data recovery? I am using Active Partition recovery to scan at the moment. No result yet.

I wanted to resize a partition, so I backuped all important files and booted from a vista PE CD. The program used is called "Easeus". After the resizing a message appeared, which told me that the system information couldnt be updated. After a restart, it - well, it didnt restarted. I tryed to format my C:Windows partition, but Easus decided to randomly format my linux partitin, too. Yey. After that i just formated everything, so i can create one big partition so this never happens again :P. To put it in a nutshel, there is no way to boot besides from booting from a cd. The diagnostic tool of the fabricator is giving me the "error code: BIOHD-3 No bootable drives detected" message.I tried to fix it with a win7 repair disk (just realized, that the disk is for 64bit, i have a 32 bit os - i think it doesnt matter, because there isnt any os installed at all). I used pretty much every "bootrec" command, sucessful, but no change. The startup repair gave this message: "the partition table does not have a valid system partition" diskpart - act isnt helping either: "The specified partition type is not valid for this operation."I dont know if i could install any os from a disk - i dont have a bootable installation cd/dvd. Because of that i would be happy if someone can tell me where i can find a free os and how i install it. From a os i can install my win 7.

I currently have a dual boot on my computer with Windows 7 and XP. Unfortunately as my computer is quite old my hard drive is not very big and with it being partitioned I am fast running out of disk space. So I tried to shrink the XP partition to allow me more disk space for Windows 7. Unfortunatley this would only let me shrink it by 83mb for some reason. I decided that since I barely use XP anymore that I would simply reformat the XP drive then try and merge them together. When I tried to format the partition it just gave the error "Windows was unable to complete the format". I then discovered in Disk Management that the Windows XP partition was the system partition which was causing the problem.

I have started the installation process of windows 7 on a clean 1 TB hard drive. In order to ensure expediency of the read time of my primary drive, I choose the custom installation. When I did I partioned the drive as 250GB & 700GB. Hoever it also created a 100MB system partition on its own. It never did this in Vista. Is it suppose to do that?

I have a system drive on a workstation which is 1) removable, 2) contains 2 partitions - one for the sytem & data files, one reserved by the os.
I would like to use this drive and it's file data in an external drive case (SATA) connected to my notebook.
Will the notebook handle the external drive properly?

I have a 2TB hard drive which i have partitioned into 3 partitions, (249GB for C:, 1000GB for D: data, 613GB for E: data). Now the 1000GB partition which is filled with data has disappeared from My computer. It happened after installing a dual boot with linux and using the 613GB as unallocated space for the linux partitions, (I have since removed the linux and partitions on the E: 613GB and created a ntfs primary partition again).
I have uploaded a screenshot that you can see that partition is not in my computer and in Disk management it only shows by "Disk 0" and not under volumes. I have tried using 'Diskpart' To assign a drive letter but under 'list volume' nothing appears. I have also done a a partition details which shows no volume, dont know if I am able to merge the partition in anyway or if the partition table that needs to be fixed

I installed two new 120GB SSD drives into my system. Previously, I had two 1TB drives in a RAID 0. After doing a performance test to see if there was a speed increase, I also bound the two new 120Gb SSDs into a NEW RAID 0.The idea was to use the new, faster array for windows, and whatever programs I am currently using, and then use the old array for storage. I could install windows on the new drives with So, I proceeded to install Windows 7 on the new array, leaving the old array alone. Installation went without a hitch. I looked at my new drive under My Computer- 1.98 TB. NOT the 240GB partition I just made, and NOT the 1.74 TB partition I used before the new drives.It, for some reason I cant fathom, combined all 4 drives, encompassing BOTH arrays, new and old HDD and SSD into one partition, and had installed windows OVER TOP OF ALL MY DATA.I dont know WHY this happened, but what do I do now to get my data back? I tried starting the computer without the new array, but it wont boot. I need my data back, and I need to get windows installed on the new array, the way I wanted.
