Error 20 Multiboot
Bug #3266 liveusb a7: Error 20: Multiboot kernel must be loaded before modules Added by Richard PALO about 4 years ago. Updated over 3 years ago. Status:ClosedStart date:2012-10-09Priority:ImmediateDue date:Assignee:-% Done:100%Category:-Target version:- Difficulty:Medium Tags:needs-triage Description the a7 iso being over 800M couldn't use cd, so I built a liveusb.Tried standard, vesa, and text ... all give the subject message.standard is nothing special, just the two following lines: kernel$ /platform/i86pc/kernel/$ISADIR/unix module$ /platform/i86pc/$ISADIR/boot_archive History #1 Updated by Patrick Arnoux over 3 years ago The file size for the liveusb distribution on openindiana is 128 MB, which seems somewhat short of the mark. The "a7" file on the UK Mirror is correct and boots, for those needing a quick solution. #2 Updated by Ken Mays over 3 years ago % Done changed from 0 to 100 Status changed from New to Closed All *.usb images and http://dlc.openindiana.org/isos/151a7/oi-dev-151a7-text-x86.iso and http://dlc.openindiana.org/isos/151a7/oi-dev-151a7-ai-x86.iso are under 500MB. Don't see this as a BUG. Also available in: Atom Loading... Powered by Redmine © 2006-2015 Jean-Philippe Lang
mistake and I hope someone can point me in the right direction.

This ISO image would only include a GRUB2 image, that would switch the device from ZeroCD to storage+modem and boot (chainload ?) from the integrated micro SD. Nicholas, understand later versions of grub2 use xorriso instead of el torito. You may want to look into this. http://scdbackup.sourceforge.net/xorriso_eng.html Sorry I cannot help you further but good luck.

and I am working as a Solaris administrator with one of the leading company. I have experienced the above issue https://kksol.wordpress.com/2012/02/12/error-8-kernel-must-be-loaded-before-booting-in-solaris-10-x86/ with solaris x86 boxes where the server is able to boot upto "grub" prompt and when you issue boot command it will through the error message as "Error : Kernel must be loaded before booting" The following action plan explains you how to resolve the issue. 1)Find out your boot disk entries first grub>find /boot/grub/menu.lst or find /sbin/init error 20 Ex: I have 2 boot environments in this machine hence entries are as follows (hd0,0,a) (hd1,0) (hd1,0,a) 2. Issue the root command against your hard disk to know the type of the file system installed in it. Ex: grub>root (hd0,0,a) File system type is ufs , Partition type 0*82 3. Load the module for multiboot grub>kernel /platform/i86pc/multiboot 4. Load error 20 multiboot the module for boot archive. grub>module /platform/i86pc/boot_archive 5.grub>boot After completion of step 5 you will be able to login to server , Cheers Krish Share this:TwitterFacebookLike this:Like Loading...

The alternate solution is as follows: 1. boot from cdrom and select the option 6 which is a single user mode. 2.If your root file system is svm or vxvm then proceed with unencapsulation and try running installgrub and update the boot-archive. 3. update the boot path in /boot/solaris/bootenv.rc and proceed with reboot Probabaly this could resolve your issue.
