Fedora 20: How to boot YUMI via fedora 20 grub2?


Hi ,

I am not using EFI/UEFI. I have a functional YUMI - a bootable usb. I cant boot directly to usb on my neighbor laptop. The laptop has EFI/UEFI features but it is disabled. Currently my partitions are:

sda1 fedora20 /boot (ext4)
sda2 fedora20 / (ext4)
sda3 windows7 (ntfs)
sda4 data (ntfs)

I wanted to add a menu entry to fedora20 grub2 so that i could boot my usb through fedora20 grub2. It is like plug my bootable usb -> power on -> fedora menu shows then i select yumi boot to usb -> then yumi menu shows -> then select systemrescuecd (something like that).

Thanks ,
mia

Why would yumi be on the internal drive? (I don't get this question exactly either)

What does neighbors computer have to do with all of this?

Hi jefro..Thanks for reply .

YUMI is a usb flash drive (external drive). I do have a lot of distro in it. I cant use it because bios dont support to boot on it. I wanted to boot YUMI via Fedora 20 Grub2. When powered on then Fedora20 Grub2 boot menu shows along with Windows7 - i also wanted YUMI to show there so that i could boot to usb and use any distro i created on it.

Thanks ,
mia

Oh, you would either need to edit grub before or use a command line to change it during boot. This would assume that the grub you have can boot to a usb and if F20 I'd think it could.

There may be some issues with how grub names stuff so you'd have to work on names. Then grub should allow you to chain to this usb. Pretty sure you'd have to chain load it. It would be how yumi loads as to exact means. If syslinux or if grub or grub4dos or what.

Maybe someone else would know for sure.

for chainloading it will be something like this at the grub2 prompt:
Code:
set root=(hd1)
chainloader +1
boot
The hd1 may be something different. yumi uses syslinux for the initial boot, but also uses grub4dos to boot isos directly.
