The actual problem is the ALERT! message. Missing modules (cat /proc/modules ls /dev)ДЇollowed by an ALERT! message (missing device). Check root= (did the system wait for the right device?) Check rootdelay= (did the system wait long enough?) Understand what the system is telling us and see if we can figure it out. Now that we know where to focus our effort, let's take a look at the error messages again. GRUB problems are most likely not an issue here.

HOW TO BOOT PEOPLE OFFLINE WITHOUT BOOTING YOURSELF UPDATE

Nevertheless, you should ask yourselves whether you have manually changed anything in the GRUB menu during orДЄfter the system update just before the reboot that brought your machine into this state. We're past GRUB, so GRUB should be OK, too.

We are in theД«oot stage before the kernel, so there seems to be nothing wrong with the kernel. Initrd.img files there, one for each kernel version that was installed.ДЄll right, now we understand that something went wrong with our initrd.img file, most likely. Open the /boot directory and see that you may have several instances of

HOW TO BOOT PEOPLE OFFLINE WITHOUT BOOTING YOURSELF DRIVERS

Whenever your kernel is upgraded, a new initrd.img file is built, containing the latest drivers for your If initrd.img is missing some modules, your system may not

Initrd.img, under the /boot directory in your Linux

These drivers are contained in a file called Includes disk drivers, USB drivers and maybe a few more. Initramfs uses a very small subset of drivers (called modules in Linux) to setup the hardware. Used to initialize devices so that the real kernel can load. This is a temporary file system that is loaded into memory and is The second step in the boot sequence is the loading of a very small filesystem called Initial RAM File System It begins with BIOS, which is a basic input/output system,Д«urned into the computer hardware and is used to initialize the hardware components. The boot sequence is a long and complicated one. While this gives us a good lead, I would like to postpone using any of the solutions for later. Refer to Google, you will find a handful of links that point mainly to Ubuntu forums, where this problem isДiscussed, with several solutions offered. Problem seem to be the words busybox, initramfs and alert messages about devices/disks not existing. To be able to solve the problem we need to focus our effort. This problem, so that you have a clear methodology for handling similar issues in the future.Д¬ompareВ the system state before the update and after the update ITNinja has always been a great resource so I know someone will be able to provide some useful info.For less experienced users, understanding what went wrong can be difficult. Is there an easy way to deploy an existingВ legacy BIOS image, switch to UEFI and then recapture as a UEFI image to simplify testing? Would we need to create a new KBE or would our existing ones created earlier this year continue to work fine for our existing images?ДЄfterВ I switch the pxe and our existing images can still be deployed to our systems I'll begin investigatingВ capturing/deploying UEFI images for the future. Our DHCP is being handled by InfoBlox and we are imaging mostly Dell systems such as 90XX, 70XX, and a few old 780 and 380 systems over a LAN. I don't have any idea of what needs to be configured and changed. What changes need to be made on the K2000 and DHCP server etc.

Once, I can get pxe working without pxe-linux and I can deploy my existing images to legacy BIOS systems I will upgrade to K2000 6.0 and hopefully everything continues to work. I would like to make configuration changes to continue pxe booting from legacy BIOS systems and if possible to also allow pxe booting to UEFI systems so that I can begin working on new images. We are only imaging systems with legacy BIOS currently. We currentlyВ run version 5.1 of the K2000 Deployment server and are hesitant to upgrade to version 6.0 because we know it will break pxe booting since pxe-linux is now deprecated in 6.0.
