C Partition Just Disappeared Along With OS?
Mar 5, 2012
my computer last night randomly shut off while loading a tv show off Internet. upon restarting windows failed to boot. when prompted with restore and recovery it failed. unable to access safe mode and when it says it is recovering it just says it is finished with no progress restarts to no avail. upon looking at command prompt diskpart, my c partition(30gb) no longer is visible or exists. this is where my windows seven was stored. so i now only have my e drive partition which is a (1 tb drive) repairs do not work, the only option i have is to install on my e drive which warns me it will overwrite my data. i would like my c drive back and be able to boot successfully.

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'm using a 500GB hard drive that is split in to 2 partitions. The primary partition is 50GB, primarily for the OS. The second is the rest of the usable space on the drive, and has all the photos, documents, etc stored on the computer. Today I decided to finally install the Windows 7 RC that I've had sitting around. I moved over any important information on the C drive, the primary partition, over to the D drive, the larger partition, popped the disk in, and in setup, formatted the C drive. I finished the install without incident, but upon getting in to Windows 7, found my second, larger partition, had vanished.

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 created a 20gb partition on my external hard drive and no longer require the partition. It is currently unallocated space so I want to format it into NFTS. Using computer management the partition was selected and and I went through the steps to format but i keep on getting an error message saying there is not enough space on the disk to complete this operation.

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?

I wanted to create a new partition to try out linux. So I decided to shrink E: by 20 GB. I then formatted the free space into a new drive by right clicking and creating new simple volume. I was warned that the drive would be made "simple", but not knowing the implications, I went ahead with the procedure. Now on rebooting, windows won't load. I had made a repair disc, so was able to use it to check for any start up errors. It reported none. Moreover I used "diskpart" through cmd to find volume c: is dynamic.

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 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 just cloned two partitions from a resident HDD to an auxiliary Momentus XL HDD in an enclosure that is connected to the computer via eSATA.Is there a way to compare each cloned partition with its original for integrity? If this were just a file, I'd use a unix/cygwin utility like diff or cmp.However, it is a partition.

I'm preparing a fresh install of Win 7 Pro on a 2 disk system (90GB SSD and 1TB HDD). I'll be placing the OS/Apps on the SSD and Data and image restore files on HDD.Qs:1. If I allocate ~60GB for the OS/Apps partition, and actual storage of the OS/Apps is 35GB...what size partition do I need on the HDD to save this image file? I assume the compressed file will be 45-50% of original. Will I want to store multiple image files created over the course of time as apps are added and system is further optimized, and hence need a partition that is a multiple of the OS/App partition size? What do you do?2. Also, an 8GB RamDisk will serve as scratch disk space for some apps (RamDisk +) which can save an image of the session's writes upon shutdown. I plan to save this image to the 2nd HDD. Is it recommended that I save this to same partition that stores the OS/App image in Q #1 above,

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 am trying to keep the size of Image Files as small as possible. I'm told that it helps to keep these files from getting too big if I move the Page File away from the drive being imaged - in this case , my C: bootable drive.

The Dell Inspiron, with Windows 7, we bought our daughter last year worked fine until she left last May for an internship. We ran scan disc before the lap top was packed. When she arrived at her destinaction it did not work. According to the Geek squad, the hardware works fine, but there is not an operation system on the laptop. The laptop did not come with discs, but it has the Windows 7 label on the back with the product code. But when emailing Micrsoft support, they only want the PID which can't be retrieved from a computer that doesn't have an operating system.

So, I'm on Home Premium 64 bit, and today everything was working just fine. After one reboot, nearly all the icons on my desktop were blank. As in, the individual icon pictures were just default. Every program I try to open all pops up with "Such and such file has been moved or Deleted" When running programs manually, I keep coming up with "Cannot run .ini or something to that effect if that helps. . The only thing I can get to work are Malwarebytes, Avira and Internet Explorer so far that I can find. No viruses have been detected by either of the scans and I just have no idea what to do from here. All MP3 files are also useless due to every media player that I have now appearing missing including WMP, Winamp, ITunes and such.
I really have no idea what to do here. The last thing I'd want is to have to format the computer. I have one 4gig thumb drive to back up some things, but that's about all I have. If those files aren't corrupted as well. I have no way of opening them to see.Tried a system restore before posting this and the restore failed.I know I am probably not providing all the information that I can, but if you need any more, please let me know. I'll be monitoring this thread all day.

I have had Windows 7 installed on my PC.Last night I installed Windows XP Professional (as i have some programs that do not work on 7) on my PC. I had intended it to be a sort of double boot with Windows 7 i.e. i wanted to have a boot selecter where i can choose whether to boot XP or 7. However my PC now directly boots into XP and does not allow me boot into 7.Is there a way to re-insert Windows 7 into the mbr so that i can have a choose which OS i want to boot?.

I am trying to fix a Samsung laptop for a friend. She admits to having 'fiddled' with the networking applets in Control Panel with the result that neither LAN nor Wi-fi functions any more.I have noticed that I am unable to use the GUI to access IPv4 Properties because the button is greyed out. Also greyed out is Uninstall. The only button available is Install. I have tried that, but after rebooting the situation appears to be the same. I have tried using the command prompt as Administrator and using NETSH to uninstall IP, install it, reset it etc, rebooting every time but without any noticeable change afterwards. Also tried NETSH WINSOCK RESET after the above. I have also tried the above in recovery mode with networking enabled. Again, no change!Unfortunately, the model does not have a CD drive. However, it has USB ports. Fortunately, I do have a generic 32-bit Win 7 Home Premium CD - which is the operating system installed on the PC. So I could copy the CD in one way or another to an external USB drive and work from that if necessary. If I knew what I had to do!There is a lot of valuable data on the PC and I don't want to be responsible for losing it. Of course, I could try backing it all up but she has saved stuff all over the place and I am bound to miss something! Yes, I could copy the entire disk ...... I know!! But we would still have to find and retrieve the data later.

I decided to change wallpaper (desktop), but the new one didn't look nearly as good once it was on the computer. So I decided to go back to the previous wallpaper, except it has now disappeared. I've looked everywhere, and have followed various suggestions found on internet (namely on Windows 7 Forums), but to no avail.The previous wallpaper was NOT a pre-installed Microsoft wallpaper, but an image I had directly installed some months ago.I would do a search on my laptop, but cannot remember the title of the photo.Florio

When I click on "My Documents" I often then go to the Desktop by clicking to the right of a small window/bar at the top. It then opens up "Desktop", which is just above it in the"family tree". I click on "Desktop" to quickly go to it.
Suddenly this bar has disappeared. How to I get it back again?
