Cannot find disk on system, fog 1.5.9 ubuntu 20.04



  • Hello im back on new version this time ubuntu 20.04 desktop and fog 1.5.9

    So when i boot on PXE with Asus P1504J and i choice full registration option i have "an error has been detected Cannot find disk on system (getharddisk)

    I have hard disk with windows and i can boot on

    any idea ?

    Bios option [secure boot = off, fast boot = off] maybe i suspect the intel rst ?

    @Bastian Looking into this, I can’t believe its still an issue after all of these years (> 5). The only solution I can find is to switch the disk controller to ahci mode from RST. If you have a live system that was installed with RST on windows will hate you. I’ve found instructions on how to fix windows.

    The ideal solution would be for you to recreate you golden image and sysprep it on a system with the disk in ahci mode enabled. That way everything will work moving forward.

    switch in the bios to ahci instead of RST that actualy allow me to correctly boot

    Ok you have the issue that plagues most dell laptops. The intel raid controller in Raid-ON (dells term) mode plus linux plus uefi makes it so linux can’t see the disks behind the raid controller. If you change any one of the three you can image with FOG.

    So what can you do. Simply change one of the three. Well really you can only change 2.

    1. Change the disk controller from Raid to AHCI mode
    2. Change the firmware from uefi to bios mode.

    Now let me say the systems that can switch between bios and uefi mode, will let you do that one-shot in the boot menu without making it a forever change. So you can boot in bios mode and image with fog, upon reboot the computer switches back to uefi mode.

    VEN_8086&DEV_282A

    Ok this is the important bit, to translate into linux IDs [8086:282a] first appeared in linux kernel 2.6.19

    vendor: 8086 (“Intel Corporation”), device: 282a (“82801 Mobile SATA Controller [RAID mode]”)

    one second just saw your new post

    i have apparently find way to fix it that kinda weird cause when i switch in the bios to ahci instead of RST that actualy allow me to correctly boot on pxe and register the cumputer and upload image.

    but when I do that and I start in a classic way I have blue screens on windows but I can captured the image



  • @george1421
    ok so i install have install kernel 5.6.18 and still the same issue, i have try some update on widows still doesn’t work,

    and for the id the computer is on windows and i don’t find something like [xxxx.xxxx]

    In my Kernel update the newer i have is 4.19.143 so i installed it

    As I suggested upgrade to 5.6.18, that has the drivers for the latest hardware. If that doesn’t work then from a windows computer (or boot into debug mode after you manually register this computer) and get the hardware ID of the disk controller. In windows its from the device manager I need both the vendor and device ID. In FOS Linux you would run the command lspci -nn |grep -i net The answer I need is in the square brackets i.e. like [8086:142d]

    In my Kernel update the newer i have is 4.19.143 so i installed it, and i don’t use anything like raid controller or something jbob

    Do you use the intel raid controller specifically for raid or is it just in jbod mode?

    Did you upgrade to the FOS Linux kenrel 5.6.18? (FOG Configuration -> Kernel)?
