I have computer which boots to either Ubuntu 13.04 or Windows 7.I installed unetboot on Windows 7.Using unetboot i selected boot from hardisk ubuntu ultimate edition 3.5 & i restarted.Upon restarting i got prefix not found & then grub 1.99 ubuntu3.I tried booting from live cd but it is of no use & same error.
I am running dual-boot with Ubuntu 14.04 and Windows 8.1. Everything works great without needing to live boot... except one problem I can't figure out. Every time I boot into Windows, it rearranges the boot order to what appears to be default settings. Let me clarify, if I boot into Ubuntu and restart, then I go to the Grub menu.
I'm planning to set up multibooting for my computer, that is currently a Windows 8.1 computer, with Windows 8, OSX Mavericks, Ubuntu, and SmartOS using the Chimera bootloader. I know that you have to install Windows operating systems from oldest to newest, then after that I think you install OSX, and after that Linux, but I'm not sure if it matters what order you install your Linux distributions.

My revised boot order remained the same in the BIOS, but UEFI always took over even after changing the comp to legacy boot and disabling secure boot.I was able to boot from USB by pressing ESC to access
I'm moving my computer from a dual boot (Windows 7, Ubuntu 14.04) to a triple boot (Windows 7, Ubuntu 14.04, Mac OS X 10.9). I currently use Grub to start up my computer into either Windows or Ubuntu. I've done dual boot installs about 5 times on 2 different machines in the past, but I've never had the booting work through Grub. Normally I have to use Windows' boot menu.
