[LVM] operating system not found

Asked by Steve Ball

Having, apparently successfully, installed Ubuntu server, I was prompted to reboot the system to the new operating system. However, the Boot Agent has returned the errors 'No boot filename received' and 'Operating system not found'

Using Ubuntu desktop, Computer shows two icons: '500 GN Hard Disk: 255 MB Filesystem' that includes a grub folder, and 'File System', which has all the program files, including a Boot folder.

Any advice about how to get the operating system booting would be welcome.

Thanks

Thanks (for your patience)

Info given is:

Device Boot Start End Blocks ID System
/dev/sda1 * 1 32 248832 83 Linux
/dev/sda2 32 60802 488134657 5 Extended
/dev/sda5 32 60802 488134656 8e Linux LVM

the command sudo mount --bind /dev /mnt/dev
produces the error:
mount point /mnt/dev/does not exist

what am I doing wrong? I have assumed that it is SDA1 that I need to be working on?

I have completely reinstalled ubuntu server, but the server will still not boot up - still saying operating system not found.

Checked in setup - it is trying to boot from PCI BEV: IBA GE Slot 00C8 v1340

Further help needed please

I have now established, I think that the hard drives are not in the Boot order in BIOS. Nor are they in the excluded list. Could someone suggest why they are not listed, and how I can reinstate them?

Thanks for your help.

Steve

Then you will need your BIOS / Motherboard manual and see how to get them reinstated.

I see you have Logical Volume Management.
Did you install it voluntarily, because it means you will have more issues of boot ?
If it is what you wanted, did you put /boot folder in sda1 ? By doing this, you will have less issues than if /boot folder is in sda5 LVM. It's the configuration used by default in RedHat to avoid boot issues.
And I'm sorry, I don't manage LVM configuration, as I don't have one on my computers. But I can make search on Grub documentation.

For the record, in case this is useful for anyone else, I have resolved the issues:

To install and run ubuntu on a Fujitsu TX100 server, you should not run first the Fujitsu Serverview software that is supplied, as the ubuntu installation disk partitioner cannot then see the hard drives. (If you have run the Fujitsu software you can run ubuntu desktop from LiveCD and use the disk utility to reformat the drives.) However, the ubuntu partitioner does not seem to create a virtual disk from which ubuntu can be booted. Once the ubuntu installation is complete, I went into the LSI RAID utility from the BIOS and created a Virtual Disk which could then be defined as the boot location. (The Virtual Disk I created was for the whole drive - not sure this is correct, but seems to work so far.)

Thanks everyone for your ideas, which have helped me get this far.
