Dell latitude 7490 legacy boot

By tim. We recently received 10 Dell Latitudewe are having trouble deploying the image on them, it cannot seem to see the SSD. Anyone have trouble with this or resolve this before? If you are using SmartDeploy 2. Are you using the beta release by chance? If it's not, then uninstall that version and download the current version from our website, and re-create your boot media. If it is, then boot your to SmartDeploy and on the splash screen click Collect Logs. Save the resulting.

So, what was the exact error you we're receiving? It actually looks like from the logs that the deployment was successful. Is it just that the machine is auto rebooting to the USB drive? If so, you'll need to remove it and reboot the machine. Or, Deploy Wizard, Advanced Options, and choose shutdown instead of reboot so that you'll know when the deployment is finished and to remove the USB stick. Unfortunately, some UEFI devices write a firmware boot entry for the USB drive, and will try to boot to it on reboot, even if we clear out the firmware boot entries before rebooting.

We were using pxe by the way not a usb boot disk. The way the machine is configured, and the boot option need to match. If the machine is in Legacy mode, then you have to select a Legacy option.

Also, put the machine back into it's default settings, if you changed it to Legacy They were not in UEFI mode from the factory.

Best Practices Question

I ended up factory reseting them and loading the recovery media, then install the smartdeploy agent, and deploy a package and that worked. But I will have to test further, the image was created in a vm, so uefi or legacy shouldnt matter. Based on what that says, you have to select an option from the menu that matches, otherwise you will end up with no bootable device found. Here is a spreadsheet we made to try and illustrate all the different scenarios and outcomes.

Okay, I am checking now to see if this helps. I had some techs working on this for way too long and i found they changed a lot of settings all wonky in the bios.

Thanks for your help, with the one test machine I had it looks like not having "secure boot" enabled was causing the issue. Not sure if it was enable or disable from dell. Can you ensure you've followed this please? I did however find the issue. Once I changed it, it successfully booted and imaged the system and booted into Windows.

Paste as plain text instead. Only 75 emoji are allowed.One of the servers is in standby, it won't try to hand out addresses unless the active server goes down. If the active server goes down, it would behave as you designed it.

The only difference is that now the clients will actually be able to reach the standby server if needed. Big Green Man saving the day! You are very helpful sir. Let me finish this write up, ill post it here and you can let me know if i have it wrong, then we can implement it and star tuning it.

Once I have the iphelpers in place, do i need to change anything on the WDS server. There will no longer be a DHCP flag to specify a boot image. If you don't why don't you turn it off in the bios? On all our new dell systems we turn it off so we can go legacy Now UEFI will be completely disabled and you can image legacy.

The new dell systems we bought have legacy on them but they disable booting legacy to internal devices, only usb, dvd, nic, etc. We just received 50 of those laptops yesterday, let me go grab one and see if it no longer works.

I think they have internal 2. Okay, so it got approved. I added second IP helper at each site for the failover DHCP to work I removed dhcp flags 66 and 67 i added the wds server as an ip helper in the network gear Its booting to PXE now, but i am getting a "windows could not set a partition active on disk 0". I will now look into this, it could be an answer file issue.

Part of the problem could be that we have 2 answer files, the boot and then the image answer file.

dell latitude 7490 legacy boot

When I approve devices, i give them a name, join them to domain and point them to the boot answer file. The boot answer file handles the PE stuff, and then the boot answer file points them to the image to boot which has an answer file injected into the image. You might want to try cleaning the drive with diskpart. Sometimes WDS has issues overwriting existing partitions.

Got the disk part working. Needed more partitions for the EFI stuff. Partition 1 is mb for EFI. That sucks. Maybe it's fixed in Server ? Everything is much more customizable than with just WDS, and it seems like deployment goes faster, too.

As for getting Legacy boot back though, while I wish you the best since I can certainly understand the inconvenience, I personally wouldn't hold my breath, for two reasons.

And second, none of the OSes that Dell actually supports on this system actually require Legacy BIOS support, and since the overwhelming majority of customers will be running these systems on an OS that Dell does support, that's not a lot of incentive.

Again, I wish you the best of luck lobbying Dell on this, but from a practical standpoint, I consider success unlikely, and even success would just be buying you a bit of extra time rather than solving the underlying problem.

As far as I can tell, nothing can be done at the moment until Dell fixes their BIOS to allow legacy booting from an internal drive. I would like to have the option to boot in legacy mode from internal drives, too. I do not understand why such useful functionality would be intentionally omitted.

Apart from everything else, the UEFI mode is clunky and forces me to have an unencrypted FAT32 partition at the beginning of my disk to hold the bootloader, which is an obvious security issue. Crappy but workable work around. I use pxelinux at work to boot clonezilla. I have used it to boot DOS off a local disk. I have a Precision that I am using this on but it has those crappy legacy on external only limitations. Browse Community. Turn on suggestions.

PenguinJeff 1 Copper. Dell Support Resources.I'm testing a Dell Latitude and unfortunately it won't boot a legacy OS off the internal drive.

Is there a way to make the laptop boot a legacy OS off of the internal drive? I can't use this PC otherwise!

Why would Dell prevent you from booting a legacy OS off of the internal drive to begin with and allow it on an external drive? Is this done for some strange security reason? I just don't get it though if it's for security. A hacker could easily plug in a USB stick, boot up the laptop, do what they need, etc Is there a technical reason for this restriction? If yes, what is it? By the way, I tried to get an answer by calling Dell's technical support and just got the "run around". That is, I was transferred to at least 3 different people in different departments until the last one in the server group that just put me on hold and kept changing the music every few seconds.

Thanks for your response. The legacy OS that I'm trying to boot should be irrelevant for this conversation. I understand that Dell can always take the side of "oh well, we never advertised that we would support such an OS, so tough luck". I've heard that newer Intel chips don't support legacy booting. So why prevent it from working on an internal drive? If I couldn't boot a legacy OS off of an external drive then I would be satisfied with the argument that "well, newer processors don't support legacy booting".

The OS you're trying to load DOES matter -- and loading a limited driver set for flash drive boot is completely different that loading a full set of drivers for running an OS in fully protected mode. There are a number of pieces of hardware that Windows 7, for instance, does not have full support for video being one major one with the eighth-generation CPU platform.

Windows 7 doesn't fully support NVMe drives, as well. And yes, there are currently hacks that unblock the Windows update issue -- for now -- Microsoft will simply disable the hacks as we go along, or leave it for now - remember, within two years, Windows 7 goes completely end of life.Sign up today to participate, stay informed, earn points and establish a reputation for yourself!

Log in. I am testing the Latitude I usually switch from UEFI to legacy. Now legacy is external only. I am at a loss. I finally got it to image through lots of trial and error but now it only tries to boot to the network and not to the hard drive. None of which show the hard drive as a bootable device. Thoughts and ideas are welcome. My supervisor believes this to be a driver issue. I think it's a BIOS issue. Also how long does it usually take for the drivers of new models to show up in the Driver feed?

Comments jboling 2 years ago. This is a midlevel driver injection so it does not allow you to boot a kbe to a system when the kbe has not the right drivers in it I hope there will be a future solution to inject the nessesary drivers automaticly to ta prebuilt KBE, but right now you need to build it by yourself.

So I used to change boot mode to legacy in order to get the option to boot from NIC. How do I do this now? I can't imagine that the drivers will help as they are not applied until after network booting. I have been through the bios and tried everything I can possibly think of.

What am I missing? Channeler 2 years ago last edited 2 years ago. Are you sure this model supports Legacy Images? I don't have it, but looking at it's manual, I don't see it listed. Contact the manufacturer to clarify what exactly is Legacy External I don't recall seeing that before.

Hi, Did you ever resolve this issue? I have the same problem with same Dell machine Captured the image, deployed it and no bootable devices found Can you please help? Thank you! I did! I went to KaceUserCon and go t so much information. On the computer you need to change to UEFI non-secure boot and enable the network stack. You also have to make changes to your DHCP server.

If you have Server you will need to manually change this everytime you switch between UEFI and Legacy my current situation If you have you can set it to auto select.

Port 67 on the DHCP server need to be ipxe.I have been trying to enable the legacy boot options on an Inspiron 20 model That menu option in the BIOS is greyed out. It just jumps right passed it as if it doesn't exist.

I want to boot to disc. Why is this so hard?! I can't get it to allow for any boot options other than booting to the original OS. I even tried flashing the BIOS to a newer version thinking there was something wrong with it. No dice. Am I missing something that needs checked, unchecked, disabled, enabled, whatever? Or is this just MS and Dell's way of saying too bad if you want to do anything else?

I can't even boot to rescue media I believe the BIOS maybe the issue. But I was able to find a system work around to get into the machine over the weekend. If Dell has chosen to lock the boot options on this blame them, not Windows. Hopefully a Dell rep will reply to this. Thank you for the post and feedback. I'm pushing this question up the ladder and will be back in touch.

Maybe we can add a boot option the manual way once I know more. I'll have to find the names to enter, in the event we can get legacy option roms enabled maybe with a BIOS update. Example found below:. Thanks Justin. I had tried the add a boot option but it didn't see to work in the manner I expected.

But the KB you left was different than the one I had come across. I'll give that a try and see if it works any better. The steps were about the same but slightly off from the one you have here. Such an odd thing to come across when trying to boot to a disc. It's become so second nature to us that when it's moved or changed we sit there and scratch our heads a bit. Eventually we recover and move on to the new improved way.

But in the meantime, I really just want this to work the old way. Looking forward to your findings. And I'll give the "add boot option" option another go.What you're seeing is a half-step toward what Intel has planned for - the complete elimination BIOS mode. The only supports Windows 10 -- so legacy mode technically is not needed at all.

In the past I always used Legacy mode. It was confusing because I always ignored this particular box which is unchecked by default. That's not correct. If you have an image deployment environment that allows you to boot in Legacy mode and still lay down a UEFI-compatible image onto the internal drive, then you're fine.

And then of course no matter how you boot, the image you're laying down needs to be set up for UEFI booting. Hi jphughan, when you say "If you have an image deployment environment that allows you to boot in Legacy mode and still lay down a UEFI-compatible image onto the internal drive, then you're fine. In this sense, all the possibility to fix disk errors or to access it without booting it vanishes, unless probably - haven't tried it you physically unmount the HDD, connect it via a sata-usb cable to the PC while booting from another pendrive.

Is this a true scenario or do you confirm you can boot from a pendrive and still being able to access the HDD? The latter could be VERY useful in order to manage full hdd images to restore from a backup, for example, but let's stick to my question, please. This is another story, related to BitLocker encryption. We got bit by this too. We have two old and expensive pieces of equipment that require legacy OS support for their control software. I managed to automate the booting like so:.

If you want to, you can go a bit further and fix that.

Since Rufus is open source yay! Now compile the new MBR, and convert the mbr binary blob into a character array xxd -i mbr.

Recompile the rufus project and use the fresh binary to perform the steps in 2. Now when you power on the laptop you will directly boot into the OS without any prompt. I also disabled the USB port so that the drive doesn't even show up in Windows. We've been given precisely zero warning about this change by our Dell contacts and do not have the resources to just drop everything to recompile our images. Exceptionally poor form, Dell. Just awful. I don't think it's too much to expect to see prior functionality restored in the next BIOS update.

I can certainly understand the frustration once you're in the predicament, but in fairness to Dell, I don't recall Dell ever giving their customers warning about things like this. I've bought Dell products before and I never received an email saying, "The following upcoming laptops will not support Windows 7", for example, nor am I aware of other vendors doing something like that.

Did you not purchase one or perhaps a handful of units to test this model in your environment before purchasing deployment-level quantities? And in the meantime, the is still available, so it's not as if this new product launched and anyone who still needed deprecated functionality immediately became unable to continue purchasing more hardware that met their needs.

I disagree with this statement. I think that if Dell is removing expected basic PC functionality - as Intel did with their latest CPUs, there should be as much information issued to corporate customers via campaigns, highlighted in tech docs, info distributed to acc mgrs etc.

We have overDell devices. Enterprise customers keep these customer afloat. The LEAST they can do is let us know they are removing a feature you would expect from a laptop and explain why that is, offering us the opportunity to procure devices that meet our requirements, or move to another vendor. This failure to notify smacks of damage limitation to me.
