  • undo the partition without distrubing the operating system

    I have a 80 GB hard drive with partition of four, each of the 20 GB.

    c:\ drive is 20 GB and

    now with different sowftwares and windows updates I have only 3 GB of space.

    He doesn't let me worry about what will happen with the regular updates.

    Is it possible to take my operating system to another (new) hard drive of without distrubing my current operatig system?

    I can combine the rest og my space partitioned with drive c?

    Hello

    It is unfortunately not possible. An option he could do is to move its other partitions on the new drive and extend the original hard disk to its normal size of 80 GB but that would be the only real option to get more space operating system partition.

  • Help resizing partition to allocate more space to the operating system

    I shared the size of my HD between OS & Windows when I partitioned.  I do not use Windows often but it's nice to have.  I would like to allocate more space to the operating system I use the low disk space.  I've seen several posts on the removal of Windows, the partition and then re-create it with the new size.  I also saw people talk about other programs to do.  What is the best way to do it without compromising the integrity of my HD?  OS X 10.10.5 - Windows 7 SP1 64 bit

    Thank you.

    The Apple-supported method is to remove Windows (Wizard BC only) and re-install Windows on a smaller Windows partition. Third-party tools come in a variety of commercial to the OpenSource and will work with varying degrees of success.

  • Re: Reinstalling operating system on Satellite A100 without deleting the other existing partition

    Hi all

    I have a Satellite A100-912 and have not reinstalled the operating system (Windows XP) for several years, but now I think that my laptop works well below par. I have my product recovery CD (disk recovery) and it will use for the re-installation.

    I have three partitions on the HARD disk (c, d and e, respectively).

    I was wandering if it would be possible to reinstall (get as long as the factory) my operating system on the c partition without erasing the data (for example my files) on partitions d and e.

    I did this on a Toshiba Satellite L10 using suggestions in this forum, but I don't know how to do it on my own. Is the user interface for the recovery/re-resettlement is not the same thing, so I'm afraid to lose my data if I proceed with the re-install without knowing what to do.

    Could you please say on how to make the re-installation of operating system only on the c partition without deleting (data on) other existing partitions.

    Thank you!

    > I was wandering if it would be possible to reinstall (get as long as the factory) my operating system on the c partition without erasing the data (for example my files) on partitions d and e.

    No, this is not possible. The recovery disk would format the whole HARD drive and therefore the partitions created on the HARD drive would be so removed.
    I recommend you to create a backup of the files before starting the recovery procedure.

  • Recovery media no boot: lack of operating system

    Hello

    I just create the recovery media to perform a reinstallation of factory on my X 220 with a new HARD drive inside, but it does not start.

    My recovery media is a HARD 20 GB formatted NTFS drive connected via USB. The process of creating media recovery did well, but when I want to start with this using F12, I choose the USB, wait a few seconds to access the disk, and then I got the message: lack of operating system.

    Did I miss something? Do I have to change on the USB in order to really start something?

    Thanks for your help

    Well, for all the world, I called the French Lenovo Service who told me this relocation of support USB (key, external hard drive) does not work, even if you choose when you create your recovery media, you can not use it for a complete reinstall, it just doesn't work.

    Hope this helps someone in the same case.

    Lenovo send me the recovery disc in place.

  • Delete/reformat the drive hard partition (s) to activate the operating system reinstall

    I have a HP 2000 2b09wm. He just broke, gives me the error message saying in that I needed a new hard drive. Suppose the old went kaput (even though I bought this pc on eBay not a month or two before). I have a new HD and a Windows 8 reinstall the software from a dealer on eBay. I tried several routes to try to reinstall the OS, resulting in many dead ends *. I asked the dealer to help, but did not get much. The last thing he offered was to remove the partitions in the new HD. I looked at a page eHow, how to remove Partitions on a hard drive. It is said to get a CD which includes fdisk.com. I burned super fdisk (2 MB) of SFbootablecd.iso and fdisk (40 MB) of fd11src.iso. I went into the BIOS to set the boot order. I put the saved first, CD/DVD-ROM internal drive and tried the two CDs. It always starts with just a screen with this:

    Not found boot device
    Please install an operating system on your hard drive
    Hard drive (3F0)
    F2 System Diagnostics
    For more information, please visit: www.hp.com/go/techcenter/startup

    I even tried to put the CD/DVD ROM USB drive first... same results.

    So my questions to you, I guess, is first of all, why the CDs fdisk is not start? I burn the evil fdisk? Second, do you know why my OS couldn't be installed using the software to reinstall? The guy I got it (http://www.ebay.com/itm/181524428825?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) , verified_computer_specialists, has excellent comments, so I guess that the software is legitimate and the computer is actually original with Windows 8.

    Thank you.

    * A couple of the streets:

    Compatibility report - the computer has started using the Windows installation media. Remove the installation media, and then restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade. Do not select [Advanced ICustom] I do a upgrade. [Advanced ICustom] I install a new copy of Windows and deletes your programs and settings.

    Another path to the Windows installation, I get this: select the driver to install: browse folder - access the driver and then click OK.
    It gives you the list under 'Computer' which includes "CD drive (E HRM_CCSA_X64FRE_EN-US_DV5)" (resettlement software) and below, support records - sources of boot - efi --.
    Simply choose drive E itself, the message appears: load a driver: no signed device not found driver. Make sure that the installation media contains the correct drivers, and then click OK.

    Enter the BIOS and disable Secure Boot-enable Legacy boot, save & exit. Try to boot again from the disk Win 8.

  • Hard drive partition and install the new operating system

    HY,

    If I partition my hard drive and I install a new OS (E.g. Ubuntu 14.04) my warranty ends?

    Thank you

    SA

    Hello

    No, it will not void the warranty but HP only supports the problems with the original operating system and prove the operation of the equipment of the original OS.

    Do the recovery disks and keep them safe before so that you could go back to factory settings if there is no problem of partitioning.

    Recovery partition usually works after partitioning, depends on your luck, but you could make the 'Active' Partition in disk management and try for recovery if it works or not.

    Thank you

    Hello!.. How can I install a second operating system on a partition on the same hard drive under xp?... Thanks in advance!

    With the elders the older operating systems, in this case 98, has prior installation.

    Is that of Vista as soon as it does not matter what operating system is installed first to do a dual boot.

    With Vista, you can then install XP as the second installed the operating system in a dual boot.

    Reboot, or power on the laptop and immediately after that the Sony Vaio logo disappears, press the F10 key several times. This brings you to the built-in recovery Partition.

    You can reinstall the operating system from there.
