Cannot Mirror System Boot Partition On Unallocated Partition
Dec 18, 2012
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'm using Compaq Presario CQ40-627TUMy Laptop SpecIntel Dual Core Processor T4400 (2.2GHz, 80Mhz FSB,1 MB L2 Cache)- 2048MB 800MHz DDR2 Memory- 320GB 7200rpm Hard Disk Drive- 14.1' TFT WXGA High-Definition widescreen LCD panel with brightviewtechnologynd i'm using windows 7 Ultimate on boot system partition C, dual boot with linux mint. which mean i got four partition. one for linux mint. one for its swap space. one for windows 7. one for my data storage(movies,drivers,mp3,picture and etc).last few days i try to resize my C partition (120gb) to make it smaller to gain some unallocated spaces and resize the D partition because my D (almost 100gb) (ntfs/primary/data storage) almost full. i use easeus partition master v5.01.
After done resizing and restart i can't see any D partition. so i was worried that my data will disappeared. i try to look for it but there is no Drive D even on the easeus or diskpart. the only drive appears was C Drive.i remove my Linux Mint and its swap (60gb) and thinking that i could get some more free space and do some cmd prompt windows 7 repair fixmbr thing to remove the grub. then i use partition recovery to transfer those missing data from partition D to C Drive. (appears as unformatted)i try to use partition wizard home to resize it back to 300gb. and it works. but i cant make a partition. it will disappear just like that.i also try to use diskpart,command prompt diskpard, and paragon. but also not working. the C drive was shrink but theres no unallocated space and no D drive (the new create partition). i try logical partition,primary,ntfs and fat but also not working. even the unallocated space also gone. i use almost 4 3rd party partitioning software but still got no luck with it.example:i divide 300gb into 2 partition which exist the C partition 150Gb but the other one gone. i wish theres other way than format. i also done many time. doing check disk, partition table doctor, searching for bad sector. but no errors with my hdd.

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

I've an 13MB unallocated partition:
And I'm thinking of recovering it to my D (logical) drive. I've did some Google-ing and found a similar post on this forum here.
However, I can't seem to do it. Whenever I right-click on my D drive, the Extend Volume is always disabled. (Means I can't click on it ).

Yesterday I tried making partitions in my hard disk, and I failed Here's what I did:
1. run compmgmt.msc
2. Shrink C: drive
3. my hard disk' capacity shrunk from 451GB to 260GB
4. an error window appeared ("I/O device error" I think)
5. it left me no unallocated space to create partition
using compmgmt I can't extend my hdd back to 451GB, so I used MiniTool partition wizard to restore it (btw, shrinking with MT PartitionWiz resulted the same, no unallocated space)

When I run out of disk space and Disk Cleanup only removes small amount of MB, can I expand my C: partition? Because I have 200 GB unallocated space on my HDD and it's unused.

I have 500 GB harddisc on my laptop with three partitions. I wanted to split the 400gb into 300 + 100 GB. So, I went to disc management and shurnk the volume to 300GB. I saw 100GB unallocated space. But, when I try to create a new partition with that unallocate space, I get a message that 'media not writable' and the 100gb remains unallocated. I have used a software called 'MiniTool Partition Wizard Home Edition'. But, it couldn't apply the changes either.
how can I create a new partition with my 100gb unallocated space.

I bought a 3TB hard drive for my gf and did a fresh install of Windows 7. When I was creating the first partition the Win7 install auto created two more volumes, both labeled as Unalloated. I thought nothing of it as I figured I would be able to merge/create my second partion with the remaining space once Windows was up and running. However, to my dimay I can not create a partition on one of those random Unallocated volumes. I've tried to delete all partition but the one that my OS is running on and I've tried to create two then merger but when I right-click on the second (first one works) volume the option t create a simple volume is greyed out.

I created a new partition and formatted it into Fat32 so my PS3 could recognize it. Now I don't need it. I now have a 30 GB and a 100 MB partition, and I don't know how to get rid of them.

New to the forums and need some help here as I'm lost. I just got my new laptop and noticed that the C drive (O/S) was getting full and wanted to add more space. I deleted the recovery partition of 25GB so I could extend my C partition.
However, I do not have the option to expand my C drive, see the print screen link below:
I also tried using minitool partition wizard which looked to be successful but upon reboot I got an error.

Previously my machine was dual-booting Windows 7 and Ubuntu. It worked fine with no problems until I decided that I didn't use nor want Ubuntu on my machine. Disk space was getting low for my primary partition and I decided it was time to let Ubuntu go. Anyhow long story short I cleared the two partitions that Ubuntu was using through the 'disk management' tool in windows. I didn't think at the time that GRUB would be stored within these partitions and that lead to the problem of being unable to boot anything.
I made and used a repair disc via another machine and then restored the bootsector code with it. That fixed the problem of being unable to boot. Now my problem is that I'm left with around 3-4 GB of wasted space in a partition. I was wondering if this 3-4 GB could be added to my primary storage partition? I've looked everywhere in the disk manager but I can't find anything there. I'm unsure as to if there is some 3rd party software available that could fix this? That 70GB partition shall remain undisclosed.

I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.
If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?
Is there any other reason why this would not be secure? Can a virus write to the BIOS?

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.

I read up a bit on this on other threads but none of them are exactly specific to my issue.I need to expand my C partition by utilizing the free unallocated space on disk D (a separate disk) that I just made by deleting the only partition on there.I guess this is not possible through windows disk management tools but I didn't want to start downloading any 3rd party software for this before I got some guidance from here. lease take a look at the following screen and let me know if using the 238.38GB of unused (unallocated space) I can extend the C partition without having to delete that partition, having to backup the files on it or making images. I already backed up everything I had on the D partition and then went ahead and deleted it through the computer management tool.

Suddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option."
- Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice:
Boot 7 dvd to system recovery options command prompt. Type: Diskpart
list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition )
Sel vol C ( or sel vol 1, obviously use the correct letter or number)
act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.

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?

About 8 months ago, I built a computer for myself;SINGLE Hard drive, 1 T;1 Partition..Windows 7 Home Premium service pack 1..The BIOS identifies the HDD..Last week, the computer worked properly, with regular shut down.3 or 4 days later, when the PC was turned on, it booted through the Windows 7 splash screen, but the log on screen did not appear.After a spontaneous reboot, the Windows 7 repair utility informed me that the situation could not be fixed. I selected advanced options and tried 2 different restore points from about a week before the last happy event. [code]

Here is what happened to me, I had windows 7 installed on a SATA HDD. I bought an SSD and installed a fresh copy of windows 7 on the SSD. then I took out the SATA harddrive which I learned it contained the system parition. Now the new windows doesnt boot.
If I open diskpart and do a LIST VOL I only get one which is the SSD and inside I only have one partition with the windows files.
After a few comamnd I was able to see the installation when I start the recovery console. but when boot up. as soon as the little cicles for the windows logo comes up it freezes and reboots.
I tried making the volume parition active, but from what I have read, looks like I need to create a system parition. Is that possible. or do I have to reinstall from scrtach. (the old SATA drive is formated so no going back) Its just so close, i see my data intact on the drive lol but cant get windows to boot.

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 was trying to get a dual boot setup of Windows 7 and Ubuntu where I had 1 partition for Windows 7, another for Ubuntu, and a third neutral partition accessible from either OS where I would house all of my data. The problem is, my computer already had 3 partitions set up: Windows 7, the system boot partition, and one called PQService. Because I could not find a tutorial to delete pqservice, I decided to delete my system partition, even though this seemed a little more risky (apparently it was lol.) I used this tutorial: TeraByte Unlimited Knowledge Base to copy the boot files to the windows partition and delete it. I then booted into a Live CD of Ubuntu, and used Gparted to move my Windows 7 partition in order to get rid of the 100MB of unallocated hard drive space. I then attempted to restart my computer into Windows and i got an error saying that windows could not boot because of some recent hardware changes. Is there anyway I could get back into windows without reinstalling it? Do I need to figure out some way to restore my System partition? Is there someway I could get windows to boot without doing either of those?

My wife shout down her computer this morning took it on remote location for work today but never booted it up. When she got back home tonight it wouldn't boot up. I don't know what to call these screen but some Startup Repair screen. Just says Repair action: Boot sector repair, Result: Failed.I downloaded and burned to CD the boot CD for the MiniTool Partition Wizard Home Edition but I don't know what disk I am even looking for. I see 3 partitions listed for one disk.The only one with a label is BDEDrive and it's 300 MB. The other two have *: as what I would call a label. One is 297.79 GB and the other is 12.34 MB. The BDEDrive is the only with with status of Active. NTFS on that partition and Other on the big partition.

I recently acquired a 60GB SSD and want to migrate my current system hard drive to the new drive. However, when I go to the Windows Backup manager to create a system image, it wants me to copy ALL of C partition and ALL of D, when it should only be C.D drive is full of a bunch of crap that I do not want included in the system image.If there even are system files on D, by no means is copying the entire partition necessary!Therefore, is there any way to make partition D NOT a system partition?
