    Toshiba C50 :Laptops will not boot PXE

    We have just bought several Toshiba C50 laptops. Configured Bios to use CSM in bios, we are connecting to WDS to install Win7 pro image. All previous Toshiba's work fine connecting etc. These C50's will not connect to WDS, PXE-E53 no boot filename received....

    They will boot to PXE using UEFI................

    Toshiba don't seem interested, they say hey only support networking from an installed OS...

    As well as enabling CSM mode, have you also disabled the 'Secure Boot' option in the BIOS? This would normally be under the 'Security' tab....

    Done all that thanks. Was talking to Toshiba this morning again!! They are trying to tell me C50 laptop is designed for Windows 8 and with that in mind, tough luck basically! what about other OS's? sorry designed for windows 8. C850 which we have some of, work fine and they are designed for "windows 8" as well according to the sticker. I said its a Bios problem as it boots to pxe in uefi, but not csm. They can't do anything as they don't have the facility/Skills..."this is tech support", I asked who deals with bios issues etc, they said Toshiba Japan... So he's going to send a couple of emails, but no response time or idea of one... Pity because the latest batches of Toshiba laptops "before these" are really good.

    What is the exact model of the C50 you are using? Is there more to it or is that the complete name? I'm trying to find some info for you

    That's just plain weird then, the Toshiba website offers driver downloads for Windows 7 for that model! So it must be possible to install it

    What happens when you PXE boot from UEFI? I don't have a new enough laptop to hand to test it out myself.

    Could you try making a bootable USB drive to get to the deployment system? Kinda-like bypassing the native BIOS network boot system?

    Have you tried changing the BIOS away from UEFI mode AFTER the image has downloaded to the laptop? Maybe it works a little like the AHCI mode on/off for hard drives..

    have you tried updating wds/mdt to use a windows 8 boot.wim (win 8 adk) rather than the windows 7 one that may allow you to boot it up

    I had the pleasure of a Toshiba C50 yesterday... it doesn't boot off anything else other than the local disk drive. In my case it didn't have an optical drive, so I tried to boot off a USB optical drive with Secure Boot off and AHCI /CSM mode selected.

    I managed to successfully image it by removing the hard drive, imaging off a workstation and putting it back.

    I really think it's a pathetic attempt by the manufacturers to lock users to one OS - either that, it's Microsoft's attempt to make it more difficult. We wouldn't have this carp if Microsoft made a good job of Windows 8.

    Not specific to that Toshiba laptop but just found this page which talks about PXE error E53. You may need to check some settings on the WDS server

    PXE-E53 error

    i seem to remember getting that with some asus x5550s until i set the bios to csm/secure boot off and so on (cant remember specifics and different school(s) so cant look but im 95% sure i had to kill uefi mode and go round the bios twice once to kill uefi iirc once to change other settings to allow pxe boot to woek

    I've had the same problem booting off any USB device, even with Secure Boot disabled and AHCI /CSM enabled.

    The only way I managed was to remove the drive from the notebook and image from another machine.
