After using a third party partition manager program left to extend my Windows 8 partition, the system of Windows 8 start to a black screen and Windows 8 partition of the drive letter has changed

Original title: problems of Windows 8

I have Windows 7 (32 bit) and Windows 8 (64-bit) is installed in a dual boot. I tried to extend the partition of Windows 8 with a third party partition manager. Subsequently, I restarted after having learned so much.

Later, the first thing I saw was that the locked screen image is replaced by a blue color. Photos of the user are also missing. Once connected, it took a long time for windows everything ready, and I'm stuck in a black screen with the mouse pointer.

I entered in Safe Mode and found that the drive for Windows 8 letter has been changed (C: = Windows 7;) D: = recovery partition; E: = Windows 8, new drive letter; F: = Windows 8, old drive letter), I tried to change the drive letter, but it does not work.

Partition of Windows 7 works well (it is what I currently use to put this problem), and I can access the data in the partition of Windows 8. I tried the methods of different repair without result (such as chkdsk and sfc/scannow).

Can someone help me with this please? Any help would be appreciated.

Hello

I understand that you have a problem of black screen with Windows 8 and the drive letter for the partition of Windows 8 is also changed. This problem is due to the use of the third party partition manager program because it affects the registry files and causes the instability of the system.

Try to run auto repair from the Windows recovery environment and check if that helps.

Method 1: start the recovery environment with installation of Windows 8 media.

It is another way to boot the PC and launch recovery tools when something goes wrong with the operating system.

Please follow the steps below. Insert the DVD to install Windows 8 on DVD-ROM and restart your computer.

(a) once you start your computer by using the Windows DVD or the system repair disc, a black screen is displayed with the gray text "Press any key to boot from CD or DVD". Press a button on any.

(b) select the good time and the type of keyboard .

(c) click on repair your computer in the lower left corner.

(d) select Troubleshooting to Choose an option screen.

(e) click on advanced options in Troubleshooting screen.

(f) click Auto repair of Advanced Options screen.

(g) following, choose the operating system by clicking on its button.

(h) Windows 8 will be looking for problems on the hard drives and verify that all required files are intact.


Method 2: Run the restoration of the system of the Advanced Options screen.

System Restore to restore your computer to a previous state, quickly and easily without losing any of your files and personal settings. Sometimes when you install programs or drivers, they can affect some system settings and prevent other programs to function properly. You can use system restore to restore these settings to their previous state

(c) click on repair your computer in the lower left corner.

(d) select Troubleshooting from the Choose an option screen.

(e) click on advanced options in Troubleshooting screen.

(f) select System restore.

After the system restore your documents and files will always remain to their previous state.

If you do not install Windows 8 media, I suggest you connect to any other computer and create a floppy disk to install Windows 8. Using this disk, you can run the troubleshooting provided methods.

How to create the installation media for a PC refresh or reset:

  • Change the drive letter of the Partition Recovery

    After previous bad experiences in trying to separate the data files program, I took the habit on my previous computer under Windows to create another partition on my hard drive to store the data files. Out of habit I still do on my desktop PC with Windows XP (great program) rather than use the My Documents folder.

    I want to do the same thing on my new DV6-3142, I use to work and create a separate partition for my data files. I understand how to create a new partition on the HDD and reassign the drive letters for the existing partitions, but I want to use the letter D for her. However, it is the letter of the drive that is used for the recovery partition.

    Can I change the drive letter of the recovery partition to, say R without affecting the operation of the recovery process, or should I leave as D for the recovery of the system to work properly that I should never need her?

    Hello:

    You leave the name of the recovery partition and drive letter unchanged and your C drive: of the same name.

    If you change these, when you press the F11 key to start the recovery process, the program know what to do.

    I am a firm believer of it also have a set of factory recovery disks. For me, it is worth less than the investment of $20.  If your HARD drive fails after the warranty period, (or if you want to upgrade your HARD drive), your recovery partition doesn't help anyway.

  • How can I change the drive letter assigned to the partition of 'winretools' on a laptop Win 8?

    I'm just going through the process to customize a new Inspiron 14z with Windows 8. The only thing that left me speechless are all provided partitions installed on drive, thanks to a combination of everything be different on Win8, Dell make their own way and GPT formatting.  Generally, I would like to know what the devil all these partitions are for, but it is fine if it will be a slow learning process.  More precisely and immediately, I need to change the drive letter assigned to the partition of 'WINRETOOLS '.  Currently it is D:, and the problem is that 10 years from now, I'm using as my data partition D: and a number of applications, configurations, settings, etc. assume that all my files are on D:.  For example, by having all my music on D:, I can sync iTunes library and preference between machines and all results files and playlists is from a machine to another.  Same thing for my photos.  Same for a bunch of utilities like FTP consoles, sync utilities...

    In an earlier version of Windows, I would just go into management drives, right click on the partition in question, assign a different drive letter and work done.  On my machine, the WINRETOOL 2 GB partition shows not even as having a drive letter in disk management, despite the fact that it is D: in Win Explorer.  In addition, only the right click option is 'help '.  I took this option, and, despite its aspirations, it is not useful.

    How can I change this drive letter to something else?  WINRETOOLS should even have a drive letter in Explorer (some messages that I've seen indicates that it must be hidden)?  If I change the drive letter, which will break its function, whatever it is?

    ....

    My machine has a 500 GB of rotating disk that has all of the above partitions.  I shrunk the 80 GB C: partition, to create a data partition.  I've not yet formatted the unallocated space I want to solve this WINRETOOLS thing first.  Finally, there is a 32 GB of SSD that I put in place as a cache of the Intel Smart Response, and it is no longer visible to the operating system.

    At the command prompt, type the following and press "enter":

    mountvol D:\/d

    Close the command prompt.

    Drive D: letter should now be available and not used.

    Here's some info about Mountvol, it's very powerful to be safe to use it:

  • Can I change the drive letter of the recovery partition?

    HP P7-1235, Win7 64 bit running. 1 TB HARD DRIVE

    I usually partition my hard drive, so that my data is separate from the operating system and applications.  the operating system is the C: partition, and my data is generally D:.  The problem is: "D:" is used by the recovery partition.

    I can change his letter to something else, and recovery still works?

    Hello

    Well, everything has been said on this subject and its okay.

    It's better to not touch the D: partition, set another letter to your other partiion, if you change the recovery partition, you won't be able to use it.

    But you can also do a thing, you can go ahead and create your copy of the recovery disks, just enter some DVD, create your copy of the recovery Image, then you can change the drive letter of the partition Recovery to E: or even delete that.

    A copy of records RRS, you can always use them to again state of the plant, and that will reformat all your partitions, create the recovery disks and do what you want and prefer with you D: partiion.

    Thank you

  • Change the drive letter for the recovery partition

    The recovery partition is, by default, the value to D: which means that if I create a data partition, it is automatically in letters f: while this is not unacceptable, it is inconvenient.  I would like to change the drive letter of the partition data on D: and set the recovery as f partition: if I do this, it will automatically disable the ability to recover?  I am running Windows 7 Professional, which is an originally installed Windows 7 Home Premium upgrade.

    Hello Richard9, if you change the Recovery D: HP restore partition to another letter, the recovery procedure would not work if you ever need.

    If you have files HP Recovery discs, you could delete this partition and recover the capacity of hard drive D: and use the set of diskettes to restore HP recovery to reintall the original software and the partitions of the hard drive, all as they were when shipped from HP.

  • Is it possible to change the drive letter or to hide the partition System Reserved (D :)?

    As you can change the drive letter, I would recommend that you do not have. The system partition reserved y at - it crashes or recovery.

  • Change the drive letter of the system drive on Windows XP SP2

    Hello.

    There is a certain task I want to accomplish, but I can't figure out how. Here's the situation:

    I have 2 hard drives, each separated into 2 partitions. 1 disk partitions have the letters C: and G: assigned on them.

    The drive 2 partitions receive letters D: and J: . I have two installations of Windows XP, one on disk 1 (C: partition) and the other on disk 2 (D: partition).

    What I want to do is change the letter of the D: partition ( E: letter, even if it doesn't really) . As you probably know, Windows does not allow me to do that because D: is a system partition / boot. So, I was wondering if there is another way to achieve this, without risking damage to the system.

    I would be grateful for any help.

    You can correct me if I'm wrong, but I suspect it came because you installed to C on disk 1, and then, without disconnecting the drive 1, installed to D on disc 2.

    If you had unplugged disc 1 before installing the second XP on disc 2, the Windows partition on drive 2 would also named drive C. A clean re-installation of Windows on the drive with the drive disconnected 1 2 is the only way to remedy this I know.

    When you reconnect the disk 1, it will assign other letters for the partitions on disk 2 and vice versa. Having established the two XPs, I would recommend that you delete the drive letters for the other XP system using disk management.

    Hello

    I have two laptops running Vista. On each of them, I have an external USB or SATA drive that I use as a backup partition.
    I have my own backup utility, and I like to use the letter B for the backup.

    When I change sometimes the discs I've met this parameter is incorrect problem on two computers - sometimes I can change using the method above and sometimes I can't.  I tried to stop the disk cache, anti-virus etc etc etc. with totally inconsistent results so far as I can tell.

    Today I tried to boot mode safe mode (F8 at startup) and tried the same steps as before and it worked on the first attempt.

    Maybe it's worth a try.

  • Try to change the drive letter, but get the error "the parameter is incorrect."

    I am trying to upgrade my PC to run Windows 7 64 - bit on a new Intel Solid State Drive (SSD). I install Windows 7 from scratch on the new SSD (which uses the drive letter J) have just completed and changed the drive letter of my original system from C to M.

    My intention was to reuse the drive letter C to the SSD, but the Win 7 disk management tool will not allow the use of C. "All I get is a' setting is incorrect" error message.

    My first thought was to check the location of the Windows page file. It was indeed using drive J, so I put the pagefile on the D drive instead and restarted my PC.  However, this has not fixed the problem. I always get "the parameter is incorrect" when I try to use the letter C.

    What else could be the cause of this problem?

    David

    I tried a change of the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices registry but it is just screwed to the top of the new installation of Windows on the SSD (it starts in a unusable mode "is not a real installation"). I was not too concerned by what I had already made my decision to reinstall Windows 7 after making changes in bios to disable all disks except the SSD and force a boot from the installation of Win 7 DVD.

    This relocation is now complete and the new partition on the SSD system has the C drive letter. A reboot with the other shows, active records that the original disc of BONE has been reassigned to the next available drive letter.

    My problem is thus solved. If it was the only way to do so is now a moot point.
