Hey man...Thanks for the TUT. I got it working fine
Question...when you said
"where X is the letter of the partition used in the USB stick. Reboot and ensure that the PC starts from USB stick. In figure 01 you can see my 8 partitions on the same USB drive where I have Windows 7 32 & 64 BIT, WINDOWS 8 32 & 64 BIT, LINUX Pinguy 32 & 64 BIT, Easeus Todo Backup Recovery with Linux shell"
Do you mean that you can boot to all of these from the same drive? if the answer is yes, which bootloader you're using and how the hell you did it?
