Formatting Infected Win 7 System Partition
Oct 7, 2009
Just yesterday Windows 7 got infected with some kind of bug that cause it to lag, crashed programs and was apparently capable of piggybacking off USB sticks- as my eeePC could tell you. I've reinstalled a new copy of Windows 7 on a different partition of the same HDD but now I can't seem to format the old partition in either Windows Disk Management or EASEUS Partition Master. I checked the status of the disk and I think it might be because that partition is classed as Primary or System or something.
Does anybody have any programs or advice that can help?

So basically, I decided that I would get windows 7 and get a new hard disk to install it on, as my original is getting a little on the old side.
Installing the new hard disk was smooth, as was formatting it and installing windows 7 on it. However, I foolishly forgot to unplug (C:) which is the disk with Vista on it (which is the only other OS). This of course is the system disk, and so my Windows 7 disk (M:) is now reliant upon it to boot. This means I cannot format (C:).... I tried repairing the windows 7 installation (without (C:) plugged in) using the windows 7 disk, however it just told me what I already knew, and didn't repair it.
Is there anyway I can make (M:) a system disk, and therefore format (C:)? (Preferably without having to reinstall Windows 7)

Ive got a dell xps 8300 that came with a recovery partition on the hard drive. Its taking up about 19 gigs of space and is not needed as I use recovery software on my machine. I want to format this partition and merge it with the rest of the C: drive. How do I go about this. I have tried right clicking on the partition but the format choice is greyed out

So I installed XP, and can't log on to Windows 7 atm. I understand why now. However, if I just format the XP partition, will I be able to log onto Windows 7 again?

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'm in a bit of a pickle here. My CD drive won't allow me to boot from CDs anymore, for whatever reason. I have 2 partitions on my hard drive and I'm wondering if it's possible to format the main partition by copying the windows setup files to my secondary and then somehow running them from there, whilst wiping the main one. I really don't want to reinstall without formatting, but right now I have no other option.

I have a Sony Vaio with two partitions, a main one that 412 GB and another one that is 39GB. The operating system is on the main partition (412GB) but I have been having a lot of problems with it so I want to install a new Windows 7 Home Premium version.
The problem is that I do not have an external hard disk drive and cannot afford one right now. I have the Windows 7 DVD that came with the computer (Home Premium 64-bit) and I also created a USB drive off of it, and will probably be using the USB since it's much faster and smoother.
Anyway, my question is how do i install Windows 7 to the main partition (400GB one) without having to format it? I am aware that I can probably install a new version of Windows in the same partition and then the old Windows will be moved to a folder called Windows (old) but in the past I have struggled with deleting that folder and it created more problems than anything

I re-installed Windows 7 on a fresh partition this morning after I started experiencing some glitches. Got the new partition up and running with a fresh version of Win 7, but now I'm unable to delete / format the previous partition it was on. When I select format drive, after warning me all files will be lost, it says Windows is unable to complete the format. If I try and manually delete all the files, it tells me I need permission from "Trusted Installer" to make changes to certain folders.

Would anything happen to my other partition when i format win XP to win 7 in C: drive/partition?
Okay it goes like this, I have Win XP SP3 installed with two partitions, C: and E: (<----supposed to be D: ). I intend to install Win 7 Ultimate on my computer from XP SP3 and install it in C: where the current OS is at. My question is, will my E: partition prevail still? Will the reformatting touch E:?
The reason is because there is where i want to put my backups and later migrate it.

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 noticed when I went about doing a fresh install of Windows 7 on the HDD that shipped with my laptop, and using the partitioning and formatting options included in the installation routine, that when I'd do a format, the formatting would complete very rapidly. From this, I deduce that the installation routine does not perform a low-level format.Perhaps, from this I should conclude that a low-level format is completely unnecessary. Yet, I seem to remember reading somewhere online, at some point in time (note: this might have been back in the Win'95 days) that it's better to do a low-level format; to flip all the bits to zero.

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 3 identical PCs with 2 partitions: C and D.I created a system image for one PC, C only.But when I restore that system image into the other 2 PCs (using Wind7 DVD), it formats both C and D and restore.The problem is that I have data on D and I don't want it to be formatted. I only want to restore the C image.

My computer seems to be very bogged down. Many programs freeze up and do the "not responding" thing and the internet constantly needs to have pages refreshed.I have malwarebytes pro on here, I have a regular defrag schedule, I uninstall programs that Im not using. Im not sure why its doing this. I checked the task manager and there is like 50 tasks running- is that normal? The task manager cpu graph also spikes to 100 about twice a minute with zero programs running. When i run the internet the task manager cpu graph is steady 50-100. My internet is crazy slow, takes about 30-60 seconds per page to load. I make music on one program and when i render out or when im transfering a file through wetransfer.com or something "heavy" I cant do anything else, my mouse gets all choppy and slow and clicking on like another tab or something isnt happening. It basically doesnt do anything until the big things are done.
I dont understand, I used to run my media player, browse the internet with like 10 tabs open, and run like a paint program or something all at the same time. I have an external hard drive for all my music stuff so there really isnt anything on my computer, like 1 decent sized game and some personal files. I dont really do much on here.Is it possible i deleted a program or something that is a part of the computers natural operating system, and it is tripping over itself or what? Doing a system restore would basically be impossible because I have been baring with this for a while and I dont know when this started and what programs/files I would lose if I restore back a few months.

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 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 install Microsoft My private folder program. I upload in there documents and photos. One day my Kaspersky note me that inside program are virus. And all my files recognize as virus. I just think in that time maybe I install bad program and in there is virus. I remember that virus was: $e. So I just done mistake and delete them. After that I open folder and all my photos and documents was damage.
Kaspersky not have option BackUp my deleted virus. I try Restore point and no luck. So what I use Recovery programs. I try 3. But only from one I get files back. So my question is, can I recover my files with program or with other option? Or This is it and I not have any option recover? Here is one photo how look recovered files. And two files I give in here.

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 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?

A friend has asked me to install Widows 7 on a friends laptop which has XP. The laptop doesn't have a DVD drive (no drive at all) so I've had to stick the installer on a USB stick from disc using a program.The USB boots up fine on the laptop, just like a disc. I formatted 2 partitions (same drive) and tried to install windows 7 but I get this error:"setup was unable to create a new system partition or locate an existing partition"So now, I have someone else's laptop with no OS. The owner is a 70 year old computer illiterate man.i'm planning on trying to install Vista instead and if successful, upgrade to 7. I would have upgraded in the 1st place, but P can't be directly upgraded to 7.

So, my antivirus (avast 5.0) found an "infected file" which it deleted. Shortly after that, he asked me to restart the computer for a startup analysis, which i tried. My computer then restarted, and I got to a "startup repair" window, trying to resolve problems. This windows runs for about 25mn to finally tell me that it is unable to correct the problems.I of course tried to boot in safe mode, tried "system restauration" a few times, and I allways get to the "startup repair" window.I also don't have win7 installation CD because they don't give it to you with your laptop when you buy it around here (yes, I made reclamations to get it but they just answered me that if I wanted the cd I had to pay the windows7 license again, this was out of the question).
I'm actually booted on a linux usb device (and hopefully I have access to all my datas!), and I have two questions for you (maybe three in fact):1- Is there any way to reinstall the startup whole thing without the installation CD?2- Is there a file where avast's last actions are reported? I went through the log files, report folders and journal folders in my avast folders, and couldn't find any clue about the file he deleted. My idea was simply to get the name of that file to replace it manually.
