How to multiboot from USB PenDrive
I have a USB PenDrive (FAT32 file system) that has 2 boot options.
Boot option 1 = runs a program that updates my BIOS.
Boot option 2 = runs a program that executes a basic hardware test on the PC.
I don't need to access any HDD or load any operative system.
Presently, the pen drive is using a DOS bootstrap (like the one you obtain when you format a device using /s option under DOS).
My question is:
Can I use an advanced graphical bootloader to accomplish the same thing?
It would be nice to have a background bootsplash logo of the company, while the user selects one of the two boot options, using the cursor keys.
Just like GRUB...
How can I do this?
Thank you all.
