I just partitioned my C drive and now have an I: drive that I use for data, music and movies and such. My question is this: if I have to do a system recovery. Will I lose that partition? Or will Windows 7 re-install on the C: drive without touching that partition?

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 had 32 bit Windows 7 home premium provided by OEM. Recently I purchased Windows 7 professional 64 bit in order to increase my memory.(My system is 64 bit capable) I followed [1]. I am using USB for installation. I booted the system with USB. Then at disk manager I deleted all the partitions(including recovery ) Then I refreshed and click next and I got an error saying setup unable to create system partition.

I reinstalled windows 7 today, When i got to the part where i have to format my SSD it wouldn't let me so i clicked "New" Then started the install.Once installed, I go to disk management and i see "100mb EFI System Partition" Now, Before i re installed windows i had just 100mb Windows Reservered, Why do i have this EFI thing instead? When i started up my PC Before it would take about 16 seconds, Now it's around 2-3 Seconds more.why it installed this partition and can i remove it?

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 once read that someone used an XP disc to create the system partition for a Vista or 7 install. The reason being that the Vista/7 system partitions are larger than the ones XP creates.
Anyone know of this technique and if it is safe? By safe I mean 7 would run stable and reliably from a smaller system partition.
Or are there other techniques (maybe a disk partitioner) that would do the trick. I hate to see so much space "seemingly" wasted.

I am having a vexing problem possibly relating to the windows 7 system partition.I recently bought a new HP Pavilion dv-7 laptop running x64 windows 7 HE installed a 500GB 5400 RPM hard drive. I installed Fallout 3 at the time and it ran beautifully.Because the notebook had a second drive bay, and I wanted more speed, I purchased a 128 GB Crucial M4 SSD and installed it. Of course, in order to take full advantage of the SSD it was necessary to do a fresh OS install on the new drive. I installed a clean, bloatware-free version Windows 7 Ultimate x64 on the new SSD and ran as a dual boot as I moved files around and got my drivers in order. I then formatted the slower disk drive so as to leave the fresh install of Ultimate as my only OS. In this way, I planned on using the SSD for windows and crucial application data, and to partition for a dual boot with Ubuntu in the near future. The old, larger disk was meant to be used for data such as videos, music, and games.Somehow in this process, however, the 200MB system partition remained on the original hard disk that had housed the factory install of w7he. I did not notice this complication until I tried to reinstall Fallout 3 on the original disk. I need to install the game in the second drive because it is huge and space is at a premium on the SSD. The installer now gives me an error, telling me that it cannot install on the old HD because "it is a system disk". This is distressing because: 1) The data partition on the drive is NOT the system partition, which of course cannot been seen in explorer and 2) I was perfectly able to install the game on the disk when the factory OS was installed there. Anyways, I could really care less about the game. I am worried that this is going to be an ongoing problem with future installs and who knows what else.I am not 100% it is the system partition being on the same drive that is throwing a wrench into the works. I also (perhaps stupidly) chose the drive path as the location of my system restore files when I activated system restore.

I have a bit of a problem. I recently got a new SSD and configured it to make it my boot drive. I kept my old installation on my hdd and also made a new partition on that device to hold all of the program files, data, etc. Whenever I was finished installing all the programs that I had on my old setup on my new setup and had transfered all necessary documents, I figured it was time to remove the old partition and expand the new data partition to fill the drive. I used gparted to delete the old one and expand the new one.
For some reason, whenever I installed windows 7 on my ssd, it never created a system reserved partition. Everything booted up fine. After deleting my old partition, my system now fails to boot up and gives me the message "BootMGR is missing. Press CTRL+ALT+DEL to restart". Clearly, my computer is now wanting a system reserved partition.
My question is, how do I create a system reserved partition AFTER Windows 7 has been installed?
I have already tried startup repair and all of the bootrec.exe commands, but none of them seem to work.

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 am having a problem with doing a fresh install of Windows 7. It is on a Dell Inspiron 1546 with a 150 GB hard drive. There was an original install but the computer was having issues as some files were corrupted. I used the Windows 7 disc to format the hard drive and booted from CD after restarting.
However when I try to install the new Windows 7 it sits at the part where it says: Expanding files. Then after a while an error pops up that says: Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information

So the other day I decided that I wanted to try dual-booting Ubuntu 10.04 on my HP Pavilion dv7-4083cl Entertainment Notebook that already had Windows 7 Home Premium 64bit installed. I shrank the main (biggest) partition by 100Gigs and then installed Ubuntu 10.04 on that 100Gigs of unallocated space. All worked fine, except when I tried to boot Windows 7 from the grub menu, it would come up to the beginning Windows 7 animation and then it would crash. So, I downloaded a Windows 7 Recovery CD and tried a few of the tools there. I did not create a system recover image prior to my troubles, so I could not recover the easy way.
After that, I tried the Startup Repair tool, which did not work. I read somewhere to try that Startup Repair tool 2 or 3 times, which I did. The third time, it seemed to freeze; it was "working" for about 6 hours, at which point I decided that it was enough and shut down the PC. That was a mistake... From that point forward, I still could not boot into Windows, but also every time I tried to boot into Ubuntu, I had to perform a disk check, which always failed! After trying that a few times, I had had enough yet again and decided to just reinstall Ubuntu. The install seemed to work fine, but once I rebooted I could not boot into Ubuntu (or Windows 7). No matter what option I select from the grub menu (or if I push F11 to go into recovery partition), it gives me an error that says "Error: No such partition" and dumps me into a grub rescue prompt...
After releasing multiple bouts of turrets, I tried booting from my Ubuntu LiveUSB again (same one I installed Ubuntu with twice) and ran Gparted to look at my partitions. It only showed me the one 100Gig partition and said the remaining ~350Gigs were unallocated! So now I'm stuck with no bootable operating system (on my HD), and to top it off, HP just sent me their "official" recovery disks that are trying to reformat my HD and erase all my data...
I know there has to be a way to restore my partitions and replace the grub bootloader with the Windows 7 bootloader. At this point I don't care about Ubuntu at all. All of my data was on the Windows 7 partition (which I cannot access from Ubuntu to grab it).
I can provide any information that you need, but remember that I can only do so via either BIOS or by booting Ubuntu from the LiveUSB. I cannot access Windows 7. I also do not have a Windows 7 install disk as this was a refurbished HP laptop that I bought from Costco...

I was trying to restore my Toshiba Sattelite L645-S4056 to factory default and reinstall windows 7 by inbuilt recovery system. While i was formatting the computer swtiched off itself. Then i couldnot access inbuilt recovery during booting. The computer wont boot with any windwos cd. It said something like "Cannot boot.Enter a bootable disc". I then installed a linux distero by booting with a USB device.The linux system works fine but i need windows 7. It shows that my hardisk is totally empty. There is no reserved part previously occupied by recovery system.I didn't get a recovery disc with my laptop. Any other dvd wont boot. How can i install back my Windows 7? What is wrong with the system? Is there any way to get windows 7 back?

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 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.

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?

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 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 am running Windows Ultimate 32 bit. I have 2 SATA Hard Drives (one with OS), 2 SATA DVD and Blu-Ray Drives and 1 IDE Hard Drive which is configured as a slave.Second - I needed to do some hard drive trouble shooting for another computer that had a (possibly) dead IDE Hard Drive. To do this I shut down my computer, and attached the (supposedly) dead IDE Hard Drive in its place.Now - all the trouble began.After booting into the Bios, I noticed the supposedly dead hard drive did not register even though it was spinning. I kept booting into the OS to see if it would be recognized in any case - it was not.I put my working IDE Hard Drive back in - after shutting down and removing the dead IDE Hard Drive.I booted back into the BIOS and noticed my good IDE Hard Drive wasn't being recognized either. I then went into advanced Bios settings and walla - it saw my hard drive but said I needed to reboot.After rebooting I noticed the same thing with the Bios, but this time proceeded to boot into the OS.After signing on, I noticed my Good Hard Drive was no longer recognized in Explorer. I went into Administrator and Computer Management and then into Disk Management.

win7 64, home premium, toshiba r835.i have been happy with acronis in the past so without much research, i loaded acronis TI12 on my new laptop ( a mistake in retrospect).
1. after loading, acronis TI12, i turned the windows "back up" on and tried to create a systems image using WIN7 built-in capability but it failed half-way through. error: some file not found.
2. then i un-installed acronis, but now the win7 "backup your computer" capability is completely gone.
any way to restore win7's original backup/restore functionality while my laptop is fully functional orherwise??

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 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 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?
