Deleted System Partition Can't Boot
May 11, 2012
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.

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?

For some reason i have to change my partition table from MBR to GPT. So i made a backup of my c drive using Acronis. But when i tried to restore my Windows, I got a message BOOTMGR missing press cntrl+alt+del to restart. Then i came to know that ultimate edition has a hidden partition called system reserved. Is there any way to restore my windows with same programs and drivers. Something like reinstalling windows 7 x64 ultimate and replacing everything by backup except boot files?

I accidently deleted my system reserved partition I only have one system installed on my pc, so no dual boot is needed or anything, I think it created a seperate system partition because of a windows.old folder, which has already been deleted now, because it took too much space. So now when I start up my pc i get the error that my bootmgr is missing. I tried repairing it by inserting the windows 7 dvd and using the repair, but when I click on windows 7 and i try to repair it it says it's the wrong version of windows. My language settings are set correctly so that's not the problem. I then tried to do it by pressing shift + f10 to get into the command line and using the following commands: Bootrec.exe /FixMbr Bootrec.exe /FixBoot Bootrec.exe /ScanOs Bootrec.exe /RebuildBcd however the scanos and rebuildbcd can't find any windows installation. If i put in my windows 7 dvd and i startup my pc, it works fine, because it then uses the bootmgr from the Windows 7 dvd. So I thought, let's just copy the bootmgr.exe to my windows. But this didn't work either.

I recently bought a new Toshiba Portege R705-P41 which came loaded with a ton of crap so I attempted to do a clean install but somehow managed to deleted the "System" partition.Now the laptop wont boot and I stupidly didn't create a system restore point so I'm freaking out a little bit.Is there any way I can get whatever was in the System partition back so the computer will boot and I can reinstall Windows 7?

I decided a week ago to install Ubuntu 11.04 alongside my Windows 7, which as you know, created a new parition. As you also know, Ubuntu likes to use it's own boot manager. Well, I decided that I was going to download and install the Windows 8 Build 7955 (as I found on Windows 8 Forums) onto the partition that was occupied by Ubuntu.. so, I downloaded the image and then, in my disk management, deleted the entire parition that Ubuntu was installed on. I went to restart my computer to finish an AntiVirus update shortly thereafter, and got a message saying something along the lines of "Grub error; unknown filesystem." I attempted a repair with my disc and nothing worked.Right now, I am installing Windows 7 on the new parition in the hopes that I can get it working again, just to get at my files on the main parition. If not, I do have a SATA-to-USB adapter that I can use to manually extract the files onto another computer, and then just wide the drive entirely, but I'm really hoping I don't have to do that, as it would be SUCH a nuisance if I had to re-do EVERYTHING on my laptop. So, what I'm asking is, if the fresh install on the new partition doesn't work, is there any way to restore the original boot manager, or am I kinda dead in the water?

I'm planning to re-install my OS and I'm backing-up my files. Right now my 'User' files (Desktop, Downloads, My Pictures, My Music, My Documents, and My Videos) are currently located in D: (I used the 'Location' tab in the properties to move each folder from C: to D: ) Now, my question is: Would my 'User' files that are currently located in D:, be deleted when I reformat and re-install my OS in my system partition (which is C:). This came into my mind because in my understanding of moving the 'User' files using the 'Location' tab, means that the files and folders are stored in D:, but still linked in C:

I am Ranko, from Europe ( Serbia, but in the eyes of world not so desired country so I do not mention it... but great food , great parties and the most beautiful girls should compensate )Ok. What I did. During Win 7 installation on my new Lenovo G780 ( 500gb HDD ) , I have deleted system ( 0 ) partition firstWin 7 offered/created 30gb system, 30gb primary, 440gb primary 2 ( unallocated ) and one Lenovo OEM partition 1mb.As my friend said , always first go from behind but I didint. Now I am missing 30gb of space, and can not retrieve it. So if I do installation from the beginning i just have 470 GB of space to alocate to partitions ( for example 100mb system , 100gb Primary & 369gb Primary 2 )So 30GB seems lost. I have installed win 7 and run diskmgmt.msc and only 1 disk with 470gb is shown.I tried linux with that partition software and the same... it shows just 470gb of space...30GB are missing/lost/not existing.Once again... so sorry guys for posting this issue since maybe it is something that is common, but I really do not want to give up. It is not up to 30GB , it is about the principle , I have to retrieve it!

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 wasnt thinking and deleted the system reserve partition when formating to windows 7. Now I cannot boot at all. It is an asus laptop. It is stuck on the Asus screen and nothing happens. I cannot even go into the bios, nor can it read the harddrive or dvd drive or usb.

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.

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]

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.

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 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 have a brand new Windows 7 64bit build with a clean install from an Upgrade CD and noticed in BIOS that my 1st boot device must be "Windows Boot Manager" or it asks for the CD. I only have 1 storage device (SSD) in the system and when I look under Disk Management in windows, it shows a 100MB "EFI System Partition" in addition to the primary partition (which is labeled "Boot, Crash Dump, and Primary Partition" - so it seems to have the boot files on it).
My components are:
Intel i5 3570K
Gigabyte Z77-DS3H mainboard
16GB Crucial Ballistix
Intel 520 180GB SSD
LG BD optical drive
GTX 560ti
As I only have the one non-optical storage device I did not set any partition parameters at install. I Attempted to do a Startup Repair with the windows disc to maybe try and delete the EFI partition and got the "... System Recovery Options is incompatible with the version you are trying to repair" error. Not sure what that is. If Disk Management shows a healthy partition with "Boot" listed as being contained, why can I not select the SSD as boot device #1? I can boot perfectly fine with the Windows Boot Manager listed as boot device #1 and the SSD as #2, however it's not ideal.

in an attempt to get rid of my system reserved partition, i formatted my other partition with over 600 GB of pictures and files. i tried to run "active partition recovery", left it to run for over 5 hours, and all it ironically found was the system reserved partitionthe rest of my disk is currently unallocated space

I deleted the Ubuntu 10.04 partition in windows computer management/disk management. Then i shut down the computer, upon booting up i was greeted with an grub error and unable to boot into windows. I used super grub disk, now windows boots up fine now. I'm left with this now, three other partitions and a 218gb of free space. How can i allocate my free space (218gb) to my C: drive? I right click my C: drive but the extend volume is grayed out. Only the Shrink volume is selectable.

I deleted the 100 mb partition for Windows 7 yesterday because you're not allowed more than 4 partitions at one time when installing linux. So i didn't think i needed it. I deleted it realizing soon after than i required it for booting. I have a laptop so i didnt receive a Windows installation disk to correct this quickly, i have recovery disks that will work, but i don't want to have to go through updating and downloading so much again. I was curious if there was anyway i could fix this without formatting my hard drive. Like if i could download that partition from somewhere or the windows installation disk.

Ok so to start off I wanted a clean install of Windows 7 Home Premium. I had everything ready and I formatted the hard drive, deleted all the partitions and started the fresh installation of Windows 7. Then I realized I didn't extract my Windows 7 product key. Now I bought this laptop from Ebay. It is a Dell XPS 15 (L502x). I tried putting in the product key that was on the little sticker on the bottom of my laptop but it said that the key was invalid. I contacted Dell and explained my situation to them and they registered me as the new laptop owner and sent me the recovery disks. Now my question is will the recovery disks work even though I don't have a product key anymore?

I mistakenly deleted the recovery partition when I was trying to formatting the hard drive, I dont know much about how it works so what would be the best way to remake it and have it function the same way the other one did (which I also dont know how that worked) or is there a better method. This is also a new Samsung hard drive with windows 7 Home premium

I have a Lenovo 3000 G430 Laptop with Windows 7 Home Basic Edition installed. I wanted to re-partition my 250GB hard disk into 3 logical drives. I shutdown the system and change the order of boot preference to CDRom. I had a bootable CD with me along with FDISK utility on it. I boot my laptop using bootable CD and ran FDISK to delete the existing NTFS (Non-Dos) partition.After deleting all the partitions, When I tried to create a new partition, it displays me disk unallocated space of 8GB only. After this I had tried several partition utility but all of them display disk unallocated space of 8GB only.I have run into problem. Can anyone help me find and resolve the issue with Disk space reporting less unallocated space of 8GB? while the actual size of harddisk is 250GB.

Im using dell inspiron 1564.this is a dual boot system-(windows7 & ubuntu). Recently my system got affected by viruses. Even-though i have a working antivirus I get frequent pop-ups saying "threat detected". I'm tired with deleting those viruses. so decided to restore system from OEM partition to get rid of all those viruses. before installing ubuntu I had a single partition (c:), then i made it into two partitions one for ubuntu clean install. now if I restore my system to factory settings from OEM of windows7 will the partition of ubuntu get formatted or deleted?
