  • BOOTMGR is missing, press Ctrl + Alt + Delete while trying to install Windows Vista Home Premium 64 - Bit

    Now that I got my 64-bit Vista in the mail and quickly install disc he jumped in my DVD player. The installation process went well until I was asked to choose which hard drive, I tried to install Vista on. I tried to format my hard drive to this screen, I was working with Vista 32 bit before that and saw no need to divide my two work machine with two separate versions of the same operating system. After formatting the hard drive, I have been unable to click on the 'next' button and engage the next step of the installation process. There was a message is displayed to the bottom of the window, as well tell a word about the installation of a machine already running windows. I would be happy to provide further information to the topic of my problems during this step, but my problems do not stop here.

    After you notice the message described above and do not get farther in attempts to install later, I decided to try to reinstall the 32-bit version of Vista and then maybe try to upgrade to 64-bit. However when I put in the CD at retail, rather than receive messages at the start of a disc, I have met with the harsh reality of "BOOTMGR is missing Press Ctrl + Alt + Del to restart." Since then got trapped in a painful loop switching between disc 32-bit and the 64-bit disk in the hope that it would finally let me begin with him.

    In addition to this logically faulty tactics, I also searched some online solutions. I made sure that my DVD drive is first in my boot order. My computer will not yet make Flex and give me the ability to boot from a disk.

    My question is this; How can I get my computer let me boot from a disc again?

    I will probably also need help to drive problem hard he, but as I can not even in a position to provide information on this issue at the time I need to have the above resolved dilemma first.

    After loading on KnightNews link, all the stuff missing header - box of Firefox, minimize button, remove the button and the only way out of the KnightNews was Ctrl-alt-delete. I now find that any time I use Firefox, I have the same problem. I deleted the program, reinstalled, did a restore of the system, all to nothing does not. When I click on Firefox to open it, the full window appears briefly, then the whole screen is filled with the opening page Firefox.

    original title: VISTA Boot Up problem

    I have an emachine with Vista for over 2 years with no problems, but recently, when I turn on the PC I get a black screen that says: "Boot From CD-ROM AHCI.  NVIDIA Boot Agent 249.0542.  Client MAC ADDR: 00 1 D 72 A9 D7 B6 GUIDE FFFFFF... "In order to get past this screen, I press Ctrl-Alt-Del and it will then start VISTA.  The last 3 days, the Ctrl-Alt-Delete method failed the first time and I had to repeat up to 3 times.  Now I wonder how long the Ctrl-Alt-Del bypass method will last.  What can I do to get the pc to boot normally again?

    start in safe mode.

    Choose Repair computer

    Or the last known good configuration.

    If windows loads in safe mode then uninstall any recently installed.

    Maybe do a system restore to an earlier date.

    I did some research on your card and I saw that when it overheats it can cause games to lock up. Is your dusty machine inside or not properly ventilated? Looks like you have a very nice system, so I don't think you have a problem of hardware limitation.

  • No mode of the Tablet CTRL + ALT + DELETE key or Windows security?

    I just bought a laptop / Tablet HP TX2-1020US that came with Vista Home Premium.  Good so far.  I upgraded to OS to Vista Ultimate and my original SBS2008 domain-joined and worked on a large too.

    The problem is: when I'm in tablet mode, no button is "Windows Security" referred to in the prompt "press CTRL + ALT + DELETE or Windows security" in the starting System.  I end up having to convert portable mode, press CAD and convert again in tablet mode and use the biometric login each time.  Same thing to unlock the machine after an invocation of the screensaver, etc..

    HP support says they don't support "as sold" configuration, even if I am invited for an upgrade as it sets up for the first time, I am on my own if I do.  Not a very "the computer's personal again' approach to customer service... ;-)

    I thought I could reassign a touch on the surface of the Tablet--maybe the button "Mediasmart" I wouldn't need otherwise.  But the upgrade apparently took a toll on that too since the dialog box control Tablet PC Panel, in the general and the tabs button, I decidedly enigmatic after the upgrade and the tablet button ID is displayed as @BttnCmn.DLL,-2, -9, -7, etc. (for example the change in screen orientation button is @BttnCmn.DLL,-9).

    I would appreciate a solution that is running boards - the need to press CTRL + ALT + DELETE and brings me directly to where a slip of the finger is a login, or a reallocation of button so I could tap without having to disable-tablet-mode each time.

    Thanks in advance,
    Richard

    And one possible answer is:

    1. Administrative Tools | Local security policy
    2. (Elevation of privilege)
    3. Local policies | Security options
    4. Interactive logon to change: don't require CTRL + ALT + DELETE to "Undefined" to "Enabled".
    5. Close local security policy tool.

    CTRL + ALT + DELETE screen is bypassed, and the login screen is used instead (for which the fingerprint reader works fine).

    Thank you

  • How can I change the way users log on or not with Windows 7 (Ctrl > Alt > Delete login)

    I want to press Ctrl > Alt > delete when I connect like in XP.  But I can't figure out how.  I have looked in Control Panel to user accounts, but there is no option like that for Windows 7.

    > Sorry, I have not put this in question.  Once you press Ctrl > Alt > delete, I want to have a window where you type your user name and password like XP.  So first, you press Ctrl > Alt > remove and then type your user name, then the password.  Thank you.

    Hello, welcome.

    Please go: start / typing netplwiz in search programs and files / right click and run as administrator / type the password if you are prompted / go Advanced tab upper / Secure logon / check users need to press Ctrl + Alt + Delete.

  • Why pressing Ctrl + Alt + DEL to join a windows logon is considered to be a more secure logon process?

    Why pressing Ctrl + Alt + DEL to join a windows logon is considered to be a more secure logon process?

    Hi Stuckfree,

    Thank you for visiting Microsoft Community.

    From your description, I understand that you want to know why the keys Ctrl + Alt + Delete is considered a secure method.

    1 if your computer is part of a domain, the domain-wide policies may have been set that override settings that you apply on the local computer.

    2 disable the CTRL + ALT + DELETE sequence creates a "security breach." The CTRL + ALT + DELETE sequence can be read by Windows, ensures that the information in the logon dialog box that follows can be read by Windows. This can prevent programs unauthorized access to the computer.

    3. the MS-DOS-based computers (and some older UNIX-based systems), by pressing CTRL + ALT + DELETE wins the attention of the BIOS, causing a reboot of 'hot'. You can use the keyboard to shut down the operating system. On Windows computers (start with Microsoft Windows NT), the CTRL + ALT + DELETE sequence is intercepted by Windows. The advantage of the typing technique initially is to help prevent Windows is stopped by someone who doesn't have access to.

  • During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT.

    Hello

    During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT partition.

    I have 64 bit install discs for Win 7 and Win 8.1. These two install on my desktop in duel boot. I made a Flash DRIVE of each disk so I can install it more quickly.

    Problem: I get the cannot install because it is a GPT partition.

    Y at - there no way to make these 2 USB sticks work?

    Thank you, Brad

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    Your computer does not have Microsoft's Downgrade rights and you must buy a copy of Windows 7 with a valid Microsoft COA and product key.

    The screenshots below is from a laptop HP 15 t-j100... options and the configuration on your computer screens may differ.

    You will need to DISABLE "Secure Boot" and ENABLE "Legacy Support" in the "Configuration of the BIOS start-up secure" on the settings page similar to what is shown below, until you try to install Windows 7.

    After you save the changes, the computer will ask you to confirm the changes... Accept the changes by typing the four digit code and press the ENTER"" key.

    If you install Windows 7 from a USB and see a message of "load a driver - a required CD/DVD drive device is missing", it's because as 'System Configuration' > 'Config USB3.0 in pre-start' is set to 'Enabled '. This should be set to 'Auto '.

    In addition, as the factory hard drive is partitioned as TPG, you must start using the internal CD/DVD UEFI or UEFI-Key/key USB to install Windows on a GPT-partitioned disk. Turn on or restart the computer and press "F9" or "ESC", then "F9" when prompted. Select the source of boot UEFI you use and you press "ENTER".

    I suggest using Windows 7 SP1 for the best installation experience. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please note that some computers may not recognize a valid active UEFI USB Flash drive if it is formatted in NTFS and may require only a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installeror WiNToBootic. I like Rufus, because it contains options for 'Plan of GPT partition for UEFI computer' and 'FAT32'.

    If you have any other questions, feel free to ask.
