Is it possible to make a EFI file to boot Yumi USB flash drive?
I've never used YUMI; however, based on skimming its main Web page, it looks like it sets up SYSLINUX to boot various image files from the USB flash drive. This type of configuration would have to be re-done using an EFI version of SYSLINUX or some other EFI boot loader (such as GRUB 2). You could experiment with this yourself, but I don't know of any tool that does this already or explicit instructions on how to do it. The closest I'm aware of is my Managing EFI Boot Loaders for Linux page, which describes EFI boot managers generally. You might be able to piece something together after reading that (and particularly the pages on SYSLINUX and/or GRUB 2) and studying the way YUMI sets things up. This will not be a point-and-click solution, though.

2 days ago I've bought an HP Envy laptop, which comes with Windows 8 pre-installed. Before that I were using Yumi USB flash drive with a dozen of boot options to set-up the computers (e.g. re-partition the disk, setting up and repairing dual-boot Linux+Win7, etc.). However with HP Envy I didn't figure out, how to boot from Yumi USB flash drive. The main reason for this is probably that I've just met with UEFI and didn't figure out, how it works. Here is what I tried to boot from Yumi flash drive.
HP Envy boot options
With HP Envy I found, that if you press F11 on boot, you get a blue screen with "Recovery. Your PC needs to be repaired. A required device isn't connected or can't be accessed. Error code: 0xc0000225" message and with 3 options below:
Press Enter to try again Press F8 for Startup Settings Press Esc for UEFI Firmware Settings
Options "Enter" and "F8" do nothing (show the same blue screen again), while "Esc" leads to the following startup menu
F1 System information F2 System Diagnostics F9 Boot Device Options F10 BIOS Setup F11 System Recovery
And F9 option allows me to "Boot From EFI File" (I can browse USB flash drive to locate it, but this won't help while I don't have it). Therefore I have the following question(s).
The question
Is it possible to create an EFI file for Yumi? Or is it a wrong way to work with UEFI computers and I should do something different to do the usual disk-OS-boot tasks?
