BOOTMGR missing new system installation

I'm trying to install Ubuntu on a new SSD, I've used www.isotousb.com software to move the ubuntu iso to the SSD from my laptop. Now when booting the first thing that its showing is:
"Loading Operating System...
BOOTMGR is missing
Press Ctrl+Alt+Del to restart"

How can I get this working ?

Thank you

Hello
Did you follow all the necessary steps?

I'm not migrating, I'm trying to install a fresh copy, but keep getting into bumps. For example if I enter the bootable CD with ubuntu it says to "remove other media".. The latest was this, when I've tried to put the iso directly onto the SSD but now it says the booting manager is not installed..

Are you able to start live Ubuntu cd ? Not installing just starting live could be useful...

Be sure to use the last Ubuntu version

yes tried a thousand times, the error is "remove other media drives". Also I reboot once and then the keyboard doesn't work anymore. I need to shut down completely and change the usb port of keyboard, then it works but it only works the first time. Thats why i decided to move the iso directly to the ssd, but then the error was related with the lack of a boot manager which obviously is not installed as the ssd is new and hadn't had any OS's installed on it before. Maybe I should install a booting manager then try ? Any suggestions ?

>>  to move the ubuntu iso to the SSD from my laptop  <<  what exactly are you doing?
anyhow, i suggest a fresh install - and backup your data; always the best solution

I am trying a fresh install, I have no data to loose. My desktop is having one brand new SSD and a brand new motherboard. It doesn't let me boot from a CD or USB as its getting an error "Loading operating system ...

Remove disks or other media
Press any key to restart"
I have even tried to install a Windows XP from CD but the same story.

Because of the above error I have moved the ubuntu installation directly to the SSD only to get a new error saying:

"Loading Operating System...

BOOTMGR is missing
Press Ctrl+Alt+Del to restart"

There is something unclear, this error is relative to hard drive. Means that hd doesn't contain a valid file system. Try to remove USB external drives. Live can recognize the drive with the correct size ?

@ sognoct what error are you referring at ? I am trying the Live Ubuntu yes either on USB, or on CD and I got this error:
"Loading operating system ...

Remove disks or other media
Press any key to restart"

I then tried to put the Ubuntu LIVE directly onto the SSD and I got this error:
"Loading Operating System...

BOOTMGR is missing
Press Ctrl+Alt+Del to restart"

Please advise.

What is unclear is :

Appeared the request "'Press any key to boot from CD/DVD'" ?

Or do you have just ""Loading Operating System... " and then "BOOTMGR is missing" ?

which is MB model ?
Your help has saved me hundreds of hours of internet surfing.

>>  It doesn't let me boot from a CD or USB as its getting an error "Loading operating system ...<<  then it is too late - you have to access the bios before that, and set the boot priority to cd
what system is this ?  model or mobo ?
sognoct

motherboard model ?

try installing from usb, tutorial here :

Its a brand new Gigabyte 970A-D3

As I've previously explained I've already tried to install from usb or cd. Nothing worked.  And yes I've went to bios and set the boot priority to either one, and same errors appear.

No it didn't appear the "Press any key to boot from CD/DVD". Its just displaying "Loading Operating System... " and after few seconds "BOOTMGR is missing" or "Remove disks or other media"

Ok, found manual
Try F12 for boot menu ... then you should be able to boot from cd

I've already tried that, either F12 or setting the boot priority were already tried with the same outcome :-(

try disabling AHCI from bios, seems that many optical drives are not working when it is enabled

if you cannot boot from cd, either cd media or drive are defective
test both on another PC -one at a time
itudor

ASKER
Both the BluRay and DVD drives were working on the last motherboard.

I've not found the settings to AHCI yet, but I've managed to take my laptop's SSD and put it on the desktop, with the blank SSD as slave and with Ubuntu Guest account I've managed to get inside. Now I don't know where to go from here :-( because I'll get into the same issues. How can I install linux on the slave SSD without rebooting ? Please help

The EFI boot option plus instructions to use x64 bit did the trick, I'm in the middle of installation and hopefully everything goes smoothly from this point on. Thanks everyone and will update this after completing the install of xubuntu

Best Regards!

noxcho: Not every UEFI system includes legacy BIOS emulation; I suspect the author's system may be a "pure" UEFI.

This motherboard has hybrid dualBIOS means both legacy and UEFI are supported. Need to switch between them manually.

yes also had the non-efi option. Managed to get it working in the end. Thank you all.
