I was first using Windows 7 then I tried Ubuntu 13.10. It was good.

Then I wanted to try BOSS (Bharat Operating System Solutions) Linux, but it didn't install.

Till then I had formatted my two disk drives. Then when I wanted to go back to Windows. It started for once, then it didn't start. I used Boot Repair for a whole night, then using Windows install DVD I again installed Windows 7.

I want to install Ubuntu in dual boot again from a USB stick, but it displays this error message:

BOOTMGR is missing 
Press Alt+Ctrl+Del to restart

It only displays the above message when I have set the USB stick first in the BIOS boot order. The same message also appears for the boot repair disk. Otherwise when I boot from the hard disk, there is no problem with booting Windows 7.

I have already checked the steps I followed when I made the Ubuntu USB stick. I visited the Ubuntu USB stick instructions page and I followed the same steps there, but the same problem persists.

Please help.

It seems to me that something is wrong with your Ubuntu installation media. What do you use to install Ubuntu: USB stick or CD/DVD? –  Danatela Mar 13 at 6:50
