Now ive had my fair share of grub problems in the past and most of them just consisted of me booting from a live disk, then >grub >root (hd0,0) then >setup hd0 and that was it. now for some reason everything ive tried resulted in "Error 21: Selected disk does not exist". Ive tried root (hd0-4,0-5) and same error everytime. any suggestions? is it possible it doesnt like that my ubuntu is on an extended partition?

Favorite Rating: Error 21 in grub during the upgrade to newer SLES 11 (SPx)This document (7014290) is provided subject to the disclaimer at the end of this document. Environment SUSE Linux Enterprise Server 11 Service Pack 3SUSE Linux Enterprise Server 11 Service Pack 2SUSE Linux Enterprise Server 11 Service Pack 1SUSE Linux Enterprise Server 11 Situation Server was converted from running as a "physical server" to running as a "virtual machine" running on VMware infrastructure. The conversion was made by using VMware vCenter https://ubuntuforums.org/showthread.php?t=1356549 Converter.SymptomsDuring the upgrade process from a previous OS version (i.e. SLES 10 SP4, or older SLES 11 SP) to a newer version of SLES 11, an error is encountered when the grub bootloader is installed. The relevant text of the error is similar to:grub> install --stage2=/boot/grub/stage2 (hd0,0)/boot/grub/stage1 d (hd0) (hd0,0)/boot/grub/stage2 0x8000 (hd0,0)/boot/grub/menu.lstError 21: Selected disk does not existgrub> quitIf using a graphical https://www.novell.com/support/kb/doc.php?id=7014290 install, you may see the following: Resolution Revert the VM back to the snapshot before applying the update/installation.Modify the /boot/grub/device.map to point to the proper disk/partition. Ideally, you will want to use either:/dev/disk/by-idor/dev/disk/by-uuidReboot and run the upgrade again. Cause After conversion to a virtual machine, the /boot/grub/device.map file no longer points to a proper device. Additional Information When the server is on physical hardware, the /boot/grub/device.map file may incorporate the driver name in the device. In our example it read like:(hd0) /dev/disk/by-id/cciss-xxxxxxxxxxxxxxxxxxxx(hd1) /dev/disk/by-id/cciss-xxxxxxxxxxxxxxxxxxxxAfter being converted to a virtual server, the old name will only work as long as grub isn't modified -- which occurs when upgrading to a new OS version or service pack. Therefore, in order to avoid this error, use the appropriate entry in /dev for your device. Try to avoid using disk names, like cciss devices, and use the links to your disks under /dev/disk/by-id or /dev/disk/by-uuid -- pointing to devices similar to /dev/sda, /dev/sdb... in most of configurations).############################################################################Here is an example. Before upgrading my machine, I see that /boot/grub/device.map shows:(hd0) /dev/disk/by-id/cciss-3600508b1001039565a353152494a0000(fd0) /dev/fd0and that my /boot is on partition /dev/sda1

You should not ask questions in this forum. This is where you tell us how to do things and we do a peer review of the documentation you wrote. Please repost in the boot-login forum, with full details. -- Cheers / Saludos, Carlos E. R.
