800 LTS G2 Elitedesk: How to enable legacy boot on Elitedesk 800 G2

Hi all

We recently received a sample Elitedesk 800 G2 unit so that we can tailor our solution for OS deployment him before that people in our society early buying.

We use the PXE-boot legacy for deployments so I wanted to set up the machine to make Legacy Boot and set the inherited from PXE first boot order.

Since there is no documentation or the help that I could find, it is a process of trial and error.

I finally managed to get boot inherited the machine by setting secure boot "Enable and disable secure boot" "Advanced" slot and allows the setting "secure boot claire keys»

After a reboot, I was able to disable UEFI and configure the boot order inherited as you wish. Everything worked well.

To validate the procedure I returned the machine back to factory defaults and tried to follow the same steps, but now the parameter 'start secured clear keys' are grayed out and I can't set 'enable and disable secure boot '.

Anyone know how I can get back to boot legacy now? Any help would be greatly appreciated.

I thought about it myself, it's for the benefit of third parties:

to switch from secure boot UEFI Legacy Boot on Elitedesk 800 G2 (and others with the same firmware):

F10-configuration of the BIOS

'Advanced' - 'secure boot configuration', set 'key to secure clear boot '.

Save & Reboot

machine you ask for a code, enter it and restart.

F10-configuration of the BIOS

"Advanced" - "" secure boot configuration ".

Select 'enable legacy support '.

Save & Reboot

F10-configuration of the BIOS

Startup options: Disable 'UEFI boot order' and activate/configure "boot order of inheritance.

Save & Reboot

Yes, 4 reboots are required unless there is a quicker way that I don't know.

  • HP EliteDesk 2 800 LTS: BIOS refuses to activate Legacy Boot

    I tried boot Legacy enable and disable the Secure boot on this machine for a few days now.  My current BIOS version is 2.05 N01 11/11/2015.  It's the strangest thing.  I am able to make changes, save and make the switch successfully... but I can not inherited to activate and save.  I took action:

    -Authorized secure boot key - Reset

    -Selected Legacy allow to support and secure startup disable - Reset

    -Go back to BIOS Boot Options-->--> try to uncheck UEFI Boot Order (impossible)--> checks if Legacy Boot is available and this is a no go

    - Then come back for secure boot options and check that any of my changes saved.

    I tried to restore the Version of Bios to 2.04 but that made no difference so I put 2.05 back.

    I am looking for these machines to perform a PXE boot to capture the image of our school district, but I need to boot Legacy has to do.  After several attempts to get the inheritance to allow, I decided to simply use our Win7 Ent disk BUT cannot do as he says the "boot image selected not to is not authenticated."  Of course the difficulty I found that it was to allow Legacy Boot... which I can't do.

    I looked through the forums and found some possible solutions, but none of them have worked.  Help, please!

    Thanks for the reply.  I ended up doing the following, who worked finally(not sure why):

    -Updated BIOS back to V 02.05

    -reset back to the factory settings in the main menu

    -in the bios, set the password and return the tag property, as required by the school district, I work for---> restart

    -back in the peripheral disabled bios bootable usb and cd rom (as is the political district of tech)

    -went to ensure startup and selected options in the menu drop-down 'enable and disable the UEFI boot'--> restart

    -return to the bios, THIS TIME the check box next to the legacy menu startup options was available.  I checked the box and could also uncheck boot UEFI--> restart

    -f12 to PXE boot and magically it finally worked

    Again, it is very similar to the process that I tried at the beginning that the only difference was the amount of reboots needed to get it done.  I had a similar problem with another 800 G2 and no matter what I did it would not be PXE boot so I have restored the version of the bios on 02.04, restore factory settings and the process I just oultined above.  AND IT has WORKED on this machine.  It's a matter of incompatible with the G2s 50 or so 800 our district bought last month.

    In any case, we are able to get these machines for a PXE boot using one of two methods that I have just mentioned.  We are so good at the moment.  Thanks again for your response.

  • EliteDesk 800 G2: SSD will allow only boot UEFI and not appear as a legacy boot option.

    Hello

    My company is the purchase of HP EliteDesk 800 G2, some comes with HARD drive and some with SSDS.

    Deploy us Windows 7 x 64 using SCCM using legacy startup.

    On a machine with installed HARD drive, I can configure the startup options to use legacy boot, but when I replaced the drive to an SSD the only option to start for this drive is UEFI.

    This causes the deployment fails because the player needs to be partitioned as TPG.

    On the other hand, if I disable the legacy, the UEFI boot PXE boot and partition the drive as GPT, after the deployment of a disk image is unable to start with error 0xc000000d (I guess that the cause is supported in Windows 7 because it does not work on Windows 8.1).

    Bottom line, I can install Windows 7 on a HP EliteDesk 800 G2 only if start legacy is enabled and I have partition the drive as UEFI.

    Is it possible to force the SSD at startup like legacy and not UEFI?

    This problem results from the workstation or is it applied by the SSD?

    Thank you.

    Hi Jay,.

    I appreciate you are trying to help.

    I guess that there are some problems of communication because it is a business problem and there are other technical components involved that I don't understand.

    After some research more, it seems that this problem occurs with a specific model of SSD.

    We'll just have to wait for HP support.

    Thank you.

    How to enable/disable cookies in Firefox for iOS?

    To disable or enable cookies in Firefox iOS, you need a content blocker. This is done in Safari tap Settings > Safari > block Cookies

    Focus is a nice content for devices with ios 8 and maximum blocker, this could be a nice way to block certain content, including cookies. Focus by Firefox

  • Why I can not connect on the accounts of Firefox to put in place the synchronization? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, already tried Safe Mode.

    Exactly what it says on the Tin.

    Why can't I connect to Firefox accounts to set up sync to my laptop? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, and I already tried Safe Mode. This has happened since the new Sync has been set up, so I think that nearly 30 FF. I'm now up to 34 FF version and it still does not work. I was not able to sync from the "update".

    Problem #1: Going to about: accounts and clicking the Get Started button Blue opens a blank screen. It's not even a prompt on the cookies. It's just empty. Screen attached.
    It comes from before the modules are disabled. If they are disabled in Mode safe, we go to the #2 problem.

    #2 problem: I've skimmed a thread (https://github.com/mozilla/fxa-content-server/issues/1017) and I tried connecting to sync through accounts.mozilla.com instead, but if the screen does not turn white while the modules are always enabled, "Enable cookies" warning are as far as I can get. Go to about: accounts in Mode safe mode gives the same result. I deleted all my cookies and my cache, FF restarted several times with and without active modules and still nothing. I browsed this forum of support for similar issues, and while other people have the same problem, no other threads have been solved yet. Several later versions of FF, it is far too long for this question still unresolved... Screen attached.

    I know where the Firefox Cookie Manager, and I have enabled all settings. I was even able to third party cookies (even though I shouldn't really because they are unnecessary). No difference. Screen attached.

    I looked into: config and looked up the word 'cookie' in names, but even this is useless to me since I am not a programmer and so ignorant of what mean really all of these parameters. Screen attached.

    I'm at the end of my rope here, guys. It has been for months. A year. Maybe more than a year. I don't even remember. I just got a new camera and I don't want to add all my Firefox information one by one. It doesn't seem to be a way to contact Mozilla directly, so... Someone help please...

    Ensure that you allow cookies for the domain of the accounts.firefox.com if you are not allowing cookies generally or use the cookie setting 'Ask Me '.

  • How to enable JavaScript on Firefox 32.0 to my Windows Vista desktop?

    Hello: I'm watching youtube videos were freezing after about 15 seconds. The good folks at Google lead me through troubleshooting tips. I definition standard (and slow) DSL and the other trick is to enable JavaScript. I'm not a computer expert. Pls advise me how to enable JavaScript.

    Thank you very much.

    In Firefox JavaScript should be enabled by default.

    If you want to check, and then type Subject: config in the address bar (address) as you type www.example.com

    Then in the filter box type top of page in javascript and you should find the javascript.enabled is the default value and true which means that it is enabled.

    Just to be sure, Java and JavaScript are two different things, and Java is not necessary for Youtube.

    I don't know where you Born this last driver NVIDIA but on NVIDIA page you can find the drivers for graphics used on desktop computers.
    For laptops drivers will be offered by the laptop manufacturers.
    Unfortunately for laptops you cannot find so many updates. Generally each new update offers better performance for graphics operations. On the desktop with good opportunities for cooling, it isn't so problematic but design on mobile units doesn't allow these updates only on desktop computers.

    Heat is a problem common on laptops and the design is the trade-off between performance and physical protection. So do not be surprised if you don't get this latest version of the driver on Toshiba download page.

    Where you found information about the version of the 8.15.11.8603 driver?

    Hello

    What model of printer you have?

    Assuming your eprint-enabled printer, please follow the steps below to connect to web services and get your email from the printer.

    To find printers e-mail you need to enable web services from the front panel of the printer. It is normally a button on the front panel or an option in a menu.

    The printer will be connected to your WiFI network, and once the device is activated, it should display a page with a code composed of letters and numbers. It is the e-mail address of printers (when you add a @hpeprint.com to it).

    Once you have this, go ahead and configure a connected HP account and register the printer to your account. This will allow you to manage settings of the ePrint printer but also to track the history of the work.
